Introduction

Overview

Topcon Positioning System’s HiPer GD and HiPer GGD receivers are dual-frequency, GPS+ receivers built to be the most advanced and compact receiver for the surveying market. The HiPer GD and HiPer GGD are multi-function, multi-purpose receivers intended for precision markets. Precision markets means markets for equipment, subsystems, components and software for surveying, construction, commercial mapping, civil engineering, precision agriculture and land-based construction and agriculture machine control, photogrammetry mapping, hydrographic and any use reasonably related to the foregoing.

The HiPer GD and HiPer GGD can receive and process both L1 and L2 signals, improving the accuracy of your survey points and positions. The GPS+ component of HiPer GD and HiPer GGD receivers means you can access both the GPS (Global Positioning System) satellites of the United States, and the GLONASS (Global Navigation Satellite System) satellites of the Russian Federation, increasing the number of satellites your receiver can detect, thus improving the accuracy of your survey points, increasing productivity, and reducing cost.

1-2

The dual-frequency and GPS+ features of the receiver combines to provide the only real time kinematic (RTK) system accurate for short and long baselines. Several other features, including multipath mitigation and co-op tracking, provide under-canopy and lo w signal strength reception. The receivers provide the functionality, accuracy, availability, and integrity needed for fast and easy data collection.

NOTICE

For more information on the difference between the HiPer GD and HiPer GGD receivers, see Table 1-1, “HiPer GD vs. HiPer GGD,” on page 12.

Topcon HiPer GD and HiPer GGD Operator’s Manual

Principles of Operation

Surveying with the right GPS receiver can provide users accurate and precise positioning, a requirement for any surveying project.

This section gives an overview of GPS and receiver functions to help you understand and apply GPS principles, allowing you to get the most out of your receiver.

GPS Overview

The Global Positioning System (GPS) is a satellite-based, lineof-sight radio navigation system run by the United States Department of Defense (DoD). This system offers a global, all weather, 24-hour positioning, velocity, and time service to any user equipped with a GPS tracking receiver, who is on or near the Earth’s surface. The Global Navigation Satellite System (GLONASS), is the Russian Federation Ministry of Defense counterpart to GPS. At any one time, with a standard 15 degree angle, up to 10 or 12 GPS satellites are visible from any point on earth. When a receiver can also track GLONASS satellites, between 10 and 16 satellites are visible.

For information on current GPS constellation status, visit the U.S. Navel Observatory website (http://tycho.usno.navy.mil/) or the U.S. Coast Guard Navigation Center website (http:// www.navcen.uscg.gov/).

Despite numerous technical differences in the implementation of these systems, both GPS and GLONASS ha ve three essential components:

• Space – GPS and GLONASS satellites orbiting

approximately 12,000 nautical miles above Earth and are equipped with a clock and radio. These satellites broadcast digital information (ephemerides, almanacs, time frequency corrections, etc.).

P/N 7010-0626 www.topconpositioning.com

1-3

Introduction

• User – The community and military that use GPS/ GLONASS receivers and the corresponding satellites to calculate positions.

• Control – Ground stations located around the Earth that upload data, including clock corrections and new ephemerides (satellite positions as a function of time), to ensure the satellites transmit data properly.

Calculating Positions

Once the receiver locks on to a satellite, it starts recording measurements and receiving the various digital information (ephemeris, almanac, and so on) the satellites broadcast. To calculate a position, receivers use the following basic formula:

Velocity x Time = Distance

Where Velocity is the speed at which radio waves travel (i.e., the speed of light) and Time is the difference between the signal transmission time and signal reception time.

To calculate absolute 3-D positions—latitude, longitude, altitude—the receiver must lock on to four satellites. In a mixed GPS and GLONASS scenario, the receiver must lock on to at least five satellites to obtain an absolute position.

1-4

To provide fault tolerance using only GPS or only GLONASS, the receiv er must lock onto a f ifth satellite. Six satellites will provide fault tolerance in mixed scenarios. Usually, the number of GPS and GLONASS satellites in view does not exceed twenty (20).

Once locked on to a satellite, the receiver collects ephemerides and almanacs, saving this information to its NVRAM (Non-Volatile RAM).

• GPS and GLONASS satellites broadcast ephemeris data cyclically, with a period of 30 seconds.

Topcon HiPer GD and HiPer GGD Operator’s Manual

Principles of Operation

• GPS satellites broadcast almanac data cyclically with a

period of 12.5 minutes; GLONASS satellites broadcast almanac data cyclically with a period of 2.5 minutes.

GPS Positioning

Achieving quality position results requires the following three elements:

• Accuracy – The accuracy of a position depends upon

the number, signal integrity, and placement (also known as Dilution of Precision, or DOP) of satellites.

–Differential GPS (DGPS) strongly mitigates atmospheric and orbital errors, and counteracts antispoofing signals the US Department of Defense transmits with GPS signals.

–The more satellites in view , the stronger the signal, the lower the DOP number, providing more accurate positioning.

• Availability – The availability of satellites affects the

calculation of valid positions. The more visible satellites available, the more valid and accurate the position. Natural and man-made objects can block, interrupt, and weaken signals, lowering the number of available satellites.

• Integrity – Fault tolerance allows a position to have

greater integrity, increasing accuracy. Several factors combine to provide fault tolerance, including:

–Receiver Autonomous Integrity Monitoring (RAIM) detects faulty GPS and GLONASS satellites and removes them from the position calculation.

–Wide Area Augmentation System (WAAS) creates and transmits DGPS correction messages.

–Five or more visible satellites for only GPS or only GLONASS; six or more satellites for mixed scenarios.

P/N 7010-0626 www.topconpositioning.com

Introduction

–Current ephemerides and almanacs. –Several algorithms to detect and correct faulty

information.

Conclusion

Surveyors can use Topcon GPS+ receivers to collect data from a network of satellites and control stations to triangulate precise points anywhere on Earth.

This overview simply outlines the basics of GPS and GLONASS positioning. For more detailed information, visit the TPS website (www.topconps.com/gpstutorial/).

Receiver Overview

When power is turned on and the receiver self-test completes, the receiver’s 40 channels initialize and begin tracking visible GPS and GLONASS satellites. Each of the receiver’s channels can be used to track C/A-L1, P-L1, or P-L2 signals. The number of channels available allows the receiver to track simultaneously all visible GPS and GLONASS satellites at an y time and location. The combination GPS and GLONASS (GPS+) antenna receives the different signals for processing.

1-6

An internal or external GPS+ antenna equipped with an optional low noise amplifier (LNA) and the receiver’s radio frequency (RF) device are connected with a coaxial cable. The wide-band signal received is down-converted, filtered, digitized, and assigned to different channels. The receiver processor controls the process of signal tracking.

Once the signal is locked in the channel, it is demodulated and necessary signal parameters (carrier and code phases) are measured. Also, broadcast navigation data are retrieved from the navigation frame.

After the receiver locks on to four or more satellites, it is possible to solve the so-called “absolute positioning problem”

Topcon HiPer GD and HiPer GGD Operator’s Manual

Principles of Operation

and compute the receiver’s coordinates and time (in WGS-84). All this information is stored in the receiver’s memory, which can be downloaded later onto a computer and processed using a post-processing software package. When the receiver is run in RTK mode, raw data measurements can also be recorded into the receiver’s internal memory. This allows the operator to double check real-time results obtained in the field.

Depending on your options, capabilities of the receiver include:

• Co-Op Tracking

• Multipath reduction

• Wide area augmentation system (WAAS)

• Adjustable phase locked loop (PLL) and delay lock loop (DLL) parameters

• Dual-frequency static, kinematic, real-time kinematic (RTK), and differential GPS (DGPS) survey modes

• Auto data logging

• Setting different mask angles

• Setting different survey parameters

• Static or dynamic modes

The receiver incorporates an internal modem for receiving data from a Base station. The Base station’s modem transmits the carrier phase and code measurements along with the reference station information (i.e., location and description) to the Rover’s modem.

Your receiver may be equipped with one of the following communication boards (howev er , your receiver may also be configured without a radio modem):

• UHF modem – a Pacific Crest PDL (Positioning Data Link) modem; either a 450–470 MHz or 430–450 MHz; receiving only.

• GSM – dual-band, dual-user cell phone frequency modem (Europe and Japan: 900/1800 MHz; USA and Canada: 900/1900 MHz).

NOTICE

To comply with RF exposure requirements, maintain at least 20cm between the user and the GSM radio modem.

The Base station operator is responsible for complying with local regulations for radio operation. In the US, the FCC regulates the use of radio transmitters, requiring a license. Broadcasting without a license can result in severe penalties including the confiscation of your radio and

Introduction

GPS+ equipment. Please call TPS Customer Support if you need advice on obtaining the proper license in the USA.

The internal radio modem comes with a number of preset frequencies programmed at TPS.

WARNING

The use of these preset frequencies without a license is illegal. Contact your local authorities (the FCC in the US) to use these preset frequencies.

Once the FCC, or your local authority, issues the proper licenses, your TPS dealer will program your PDL radios (Base and Rover) to enable communications.

Complete information regarding your radio system can also be found in your radio modem documentation.

Power Board

The internal power board manages receiver power and battery charging, and is connected to the receiver board and the batteries. The power board receives power from the internal batteries, even when the receiver is turned of f. This feature allows the internal batteries to charge, regardless of the receiver’s status (on or off). To prevent the batteries from discharging when the receiver is stored, put the receiver in Zero Power Mode (see “Zero Power Mode” on page 4-21 for more information). The batteries will not charge in this mode.

1-14

The power board’ s processor and firmware are independent of the receiver card. To ensure firmware compatibility, the GPS receiver board and power board must be loaded with firmware from the same package.

Introduction

Battery

The receiver is equipped with two nonremovable, on-board, rechargeable Lithium-Ion battery packs connected to the receiver’s power board. Each one of these Lithium-Ion battery packs is 7.4 V and 3 Ah, giving you a total po wer of

7.4 V, nominal, and 6 Ah when fully charged. With a full charge, the internal batteries should power both

the GPS+ receiver and the radio modem for at least 16 working hours for the HiPer GD or 12 hours for the HiPer GGD. If the internal radio modem is turned off, and with fully charged on-board batteries, the GPS+ receiver should run at least 18 hours for the HiPer GD or 14 hours for the HiPer GGD.

The Li-Ion batteries used in the receiver sh ou ld run at no less than 98% capacity after 500 charging cycles. These batteries do not need to be drained before recharging.

A battery charger (AC adapter) is included with the standard package. See Appendix B for technical specifications on the battery.

whether the receiver is turned off or on. See “Power Management” on page 2-5 fo r more information.

The Li-Ion batteries used in the receiv er shou ld run at no less than 98% capacity after 500 charging cycles. These batteries do not need to be drained before recharging.

External Batteries

In addition to the internal batteries, you can use your receiver with external batteries. The use of external batteries allo ws you to continue using the receiver in case the internal batteries are discharged. To use external batteries, you must have:

• a 12 V, 2.3 A*h battery

• a 2.3 A*h battery clip-to-SAE cable

• an SAE-to-Power Plug cable

When the receiver uses external batteries, make sure that the charger mode is set to Off. Otherwise, the e xternal batteries will also charge the internal batteries, causing operation time to decrease. See “Power Management” on page 2-5 for more information on setting the charger mode.

1. Connect the SAE ends of the battery clip-to-SAE and the SAE-to-power plug cables.

2. Plug the power cable into the receiver’s power port.

3. Attach the battery clip to the battery.

A single external 12 V, 2.3 A*h battery should run the receiver for about 7 hours and the receiver and modem for 5 hours.

TIP

Use an SAE-to-SAE extension cable and an Alligator clip-to-SAE cable, and power the receiver directly from a battery, such as the battery used to power the Base radio, or other similar battery.

Recording Interval parameter

This parameter specifies the message output interval into the log file when the MINTER FN key (pressed for 1–5 seconds) activates data logging. This setting is used not only when logging a single log file, but also when logging recei ver data in AFRM mode. Values are 1–86400 seconds.

The default value is one second.

Elevation Mask for Log File parameter

This parameter specifies the minimum elevation angle for the satellites whose data will be put in the receiver files logged when pressing FN.

The default value is five degrees.

File Name Prefix parameter

This parameter specifies what prefix will be added to the names of the receiver files created when pressing FN. The prefix can be up to 20 characters long.

The default value is log. Log file names have the following structure:

The file name depends on both the file creation time (month and day) and additional letter suffixes to avoid confusion between files created on the same day.

Always Append to the File parameter

If you want the new recei ver data to be appended to an existing log file, enter the desired filename in this parameter. The setting can be up to 20 characters long.

P/N 7010-0626 www.topconpositioning.com

2-21

Configuration

Files Creation Mode parameter

This parameter has two possible operation modes:

• Log file – If the log file radio button has been selected,

pressing the FN key will result in closing the current log file. If data logging is off, pressing FN will open a new log file.

• AFRM – If AFRM radio button has been selected, pressing

FN will enable this mode. If AFRM has been enabled, pressing FN will disable this mode.

Automatic File Rotation Mode (AFRM) parameters

TPS receivers are capable of automatically rotating log files. During a “file rotation” event, the receiver closes the current file and opens a new one according to a user-defined schedule. The Period and Phase parameters specify this schedule. File rotation launches the moment the receiver time module Period is equal to Phase. More precisely, a new log file opens immediately before the scheduled epoch causing data tagged with this epoch to be recorded to the new log file.

2-22

When opening a new log file, the receiver enables the default set of messages outputted with the default output period. Both the default set of messages and the default output period are programmable.

• Period – specifies the time duration of each log file created in AFRM mode.

Values are 60 to 86400 seconds. The default value is 3600 seconds.

• Phase – specifies the “phase” (constant time shift) of creating multiple log files in AFRM mode.

Values are 0 to 86400 seconds. The default value is zero seconds.

Topcon HiPer GD and HiPer GGD Operator’s Manual

MINTER Configuration

• Files (total) – a counter that specifies how many multiple log

files must be created in AFRM until this mode automatically turns off. This counter decrements on every file rotation until it value becomes zero, then file rotation automatically stops. The counter initializes with AFRM.

Note that a log file opens immediately after turning AFRM on. This startup file is not considered a file rotation event; the AFRM counter will not decrement.

Values are 0 to [2

Collecting Almanacs

Each satellite broadcasts a message (almanac) which gives the approximate orbit for itself and all other satellites. If the receiver has an almanac, you can considerably reduce the time needed to search for and lock on to satellite signals.

The receiver regularly updates the almanac and stores the most recent almanac in its Non-Volatile Random Access Memory (NVRAM).

1. Set up the receiver (connect the external antenna if needed) in a location with a clear view of the sky.

2. Turn on the receiver. Wait for about 15 minutes while the receiver collects almanac data from satellites.

2-40

NOTICE

If 15 minutes have passed and the receiver does not lock on to satellites, you may need to clear the NVRAM. See “Clearing the NVRAM” on page 4-18 for this procedure.

You will need to collect or update the almanac:

• If the receiver has been off for a long time.

• If the last known receiver position, stored in the NVRAM, is different from the present position by several hundred kilometers.

• After loading a new OAF.

• After loading new firmware.

• After clearing the NVRAM.

• Before surveying.

The collection and/or update of an almanac can take as long as 15 minutes.

Setup and Survey

This chapter describes:

• Receiver setup

• RTK Base station setup

• RTK Rover setup

• Basic surveying with the HiPer GD or HiPer GGD receiver

Your receiver can be used with either the internal antenna or an external antenna (with optional base station kit and optional internal radio card).

Receiver Setup

To set up the receiver, you must:

1. Configure the receiver as shown in Chapter 2.

2. Set up your Base or Rover station. See “Step 1: Set up

Receiver” on page 3-2

3. Measure the antenna height. See “Step 2: Measure Antenna

Height” on page 3-2 for internal antennas, or see “External Antenna Setup” on page 3-5 for external antennas.

4. Begin collecting data. See “Step 3: Collect Data” on page 3-5.

All receivers include an internal, micro-strip antenna. This antenna is able to capture L1/L2 signals from GPS and GLONASS satellites.

P/N 7010-0626 www.topconpositioning.com

3-1

Setup and Survey

Step 1: Set up Receiver

This section assumes you have already configured your receiv er using PC-CDU.

1. Place the receiver on the appropriate tripod or bipod.

2. Center the receiver over the point at which data will be

collected. For most applications, this should be at a location with a clear view of the sky.

3. If using the receiver as a Base station, connect the external

radio to the receiver.

Step 2: Measure Antenna Height

The location of the antenna relative to the point being measured is very important for both surveys in which the elevation of the points is important and in surveys for horizontal location only. Horizontal surveys are often larger in area than can reliably fit on a flat plane, therefore the antenna adjustment must be done in three dimensions and then projected onto a two dimensional plane.

3-2

The receiver calculates the coordinates of the antenna’s phase center. To determine the coordinates of the station marker, the user must specify the following:

• Measured height of the antenna above the station marker

• Method of measuring the antenna height

• Model of the antenna used

Antennas have two types of measurements:

• Vertical – measured from the marker to the antenna reference point (ARP) located on the bottom of the receiver at the base of the mounting threads.

• Slant – measured from the marker to the lower edge of the antenna slant height measure mark (SHMM) located on both end panels of the receiver.

Topcon HiPer GD and HiPer GGD Operator’s Manual

Receiver Setup

1. Measure the antenna height above the point or marker (see

“External Antenna Setup” on page 3-5 for external antenna measurements and setup).

Figure 3-1 illustrates the antenna offsets. (See Figure 1-4 on page 1-17 and Figure 1-6 on page 1-19 for the exact SHMM location.)

Figure 3-1. HiPer GD and HiPer GGD Antenna Offsets

3-3

Setup and Survey

The actual point to which surveying with GPS/GLONASS measures is called the Phase Center of the antenna. This is analogous to the point at which a distance meter measures in a prism. A user must enter the prism offset to compensate for this point not being at a physical surface of the prism. In the case of a GPS/GLONASS antenna, the offset is entered depending on the type of measurement taken. For vertical, the offset is simply added to the measured vertical height to produce a “true” v ertical height. For slant height, the vertical height must first be calculated using the radius of the antenna, then the offset can be added. The offsets are not the same number because of the difference in location between the slant measuring point and the vertical measuring point.

2. Record the receiver serial number, antenna height, point name, and start time in the field notes.

3. Press the power key and release it to turn the receiver on. The STAT (status) light (LED) will blink red at first.

4. Once the receiver has locked on to one or more satellites, the STAT light will blink green for GPS satellites, orange for GLONASS satellites, and a short red blink indicating it has not solved a position. Four or more satellites provide optimal positioning.

5. Once the short red blink is gone, the receiver has a position and surveying can begin. You should wait for green and orange lights before beginning data collection. This ensures that the receiver has the correct date and time, and is locked on to enough satellites to ensure good quality data.

3-4

The process of locking on to satellites normally takes less than one minute. In a new area, under heavy tree canopy, or after resetting the receiver, it may take several minutes.

Topcon HiPer GD and HiPer GGD Operator’s Manual

Step 3: Collect Data

1. To begin collecting data, press and hold the FN (function)

key for more than one second and less than five seconds.

2. Release the FN key when the REC (recording) LED light

turns green. This indicates that a file has opened and data collection has started. The REC LED blinks each time data is saved to the internal memory.

TIP

You can use PC-CDU to configure data logging. See “MINTER Configuration” on page 2-18 or refer to the PC- CDU User’s Manual for more information.

3. When finished, press and hold the FN key until the REC

LED light goes out.

4. Press and hold the power key until all lights go out, then

release.

External Antenna Setup

The receiver can also be used with an external antenna. Follow the steps below to connect an external antenna to the receiver and measure its offset.

1. Attach the antenna to a tripod or bipod and center it over the point at which data will be collected.

2. Measure the antenna height. Antennas have two types of measurements:

• Vertical – measured from the marker to the antenna reference point (ARP) located on the bottom of the antenna at the base of the mounting threads.

• Slant – measured from the marker to the lower edge of the antenna’s slant height measure mark (SHMM).

Surveying with the Receiver

The receiver can be used to perform static, kinematic, or real-time kinematic (RTK) surveying.

Static Survey

Static surveying is the classic survey method, well suited for all kinds of baselines (short, medium, long). At least two receiver antennas, plumbed over the survey marks, simultaneously collect raw data at each end of a baseline during a certain period of time. These two receivers track four or more common satellites, have the same data logging rate (5–30 seconds), and the same elevation mask angles. The length of the observation sessions can vary from a few minutes to several hours. The optimal observation session length depends on the surveyor’s experience as well as the following factors:

• The length of the baseline measured

• The number of satellites in view

• The satellite geometry (DOP)

• The antenna’s location

• The ionospheric activity level

• The types of receivers used

• The accuracy requirements

• The necessity of resolving carrier phase ambiguities

Generally , single-frequency receivers are used for baselines whose lengths do not exceed 15 kilometers (9.32 miles). For baselines 15 kilometers or greater, use dual-frequency receivers.

Dual-frequency receivers have two major benefits. First, dualfrequency receivers can estimate and remove almost all ionospheric effect from the code and carrier phase measurements, providing much greater accuracy than single-

P/N 7010-0626 www.topconpositioning.com

Setup and Survey

frequency receivers over long baselines or during ionospheric storms. Secondly, dual frequency receivers need far less observation time to reach the desired accuracy requirement.

After the survey completes, data the receivers collect can be downloaded onto a computer and processed using postprocessing software (for example, Pinnacle).

The procedure that follows describes the steps the operator should take to perform a Static Survey using MINTER.

1. Connect your receiver and computer. See “Connecting the Receiver and a Computer” on page 2-11 for this procedure.

2. Open PC-CDU, click ConfigurationReceiver MINTER and specify the following parameters, then click Apply (Figure 3-6):

5. Set up each antenna and receiver as described in “Receiver Setup” on page 3-1.

6. Begin your survey.

Kinematic Survey

You can use the kinematic survey method for either a Stop and go survey or a Kinematic continuous (trajectory) survey.

Stop and Go Survey

The stationary receiver (Base station) is set up at a known point such as a survey monument, or an unknown point. The receiver continually tracks satellites and logs raw data into its memory. The ro v er recei v er is set up at an unknown point and collects data in static mode for 2 to 10 minutes. When finished, assign the Rover to kinematic status and move to the next survey point. At this point, and each subsequent point, the receiver is changed to static mode to collect data. So, while moving, the Rover is in kinematic mode, and while collecting data, the Rover is in static mode.

Setup and Survey

6. Move the Rover to the next location (survey point), and

press the FN key for less than a second to collect the data in static mode for two to ten minutes.

7. Repeat steps five and six until all points have been

surveyed. The occupation time for the points depends on the same factors as for the static survey method.

8. When finished, press the FN key for one to five

seconds to stop logging data. Turn off the Rover if needed.

This method of GPS survey allows the operator to reduce the point occupation time, thus permitting field crews to survey many more points compared to the other methods available.

Kinematic Continuous

Kinematic continuous surveying, also known as trajectory surveying, allows the Rover to move without having to stand still, record data, move to another point, and repeat the procedure.

3-14

If the surveyor knows the coordinates of the starting point, the rover will not need to be initialized. The determination of ambiguity parameters is carried out while the rover is moving and is called “on the fly ambiguity resolution.” Furthermore, if loss of lock occurs (such as, an obstruction that prevents a clear view of the sky), the receiver will be re-initialized on the fly.

After the survey completes, raw data collected by the receivers are downloaded onto a computer and processed using post-processing software (for example, Topcon Tools).

described in “Static Survey” on page 3-9.

3. Set up the Rover at a starting point with unknown coordinates and press the power key. Pause for several minutes while the receiver compiles an almanac.

4. Check the STAT light for satellites tracked.

5. Press the FN key for one to four seconds to begin logging data in kinematic mode (the antenna status is kinematic).

6. Move the Rover receiver along the selected trajectory.

7. Once the Rover receiver reaches the end point of the trajectory, pause for several minutes.

8. When finished, press the FN key to stop logging data and turn off the Rover.

Real-time Kinematic Survey

Real-time kinematic (R TK) is a differential GPS process where information, such as differential corrections, is transmitted in real-time from a Base station to one or more Rover stations.

Setting up an RTK Base Station

To configure an RTK Base station using PC-CDU, take the following steps:

–Extrapolation is for low-latency, high frequency output (>= 5 Hz) RTK applications. The rover will extrapolate the base station’s carrier phase measurement corrections when computing the rover's current RTK position.

–Delay is for 1 Hz high precision RTK applications. The Rover R TK engine will compute either a delayed RTK position (for the epoch to which the newly received RTCM/CMR message corresponds) or the current stand-alone position (while waiting for new RTCM/CMR messages coming from the base).

• Select the antenna status during RTK, either Static or Kinematic.

• Specify the Ambiguity fixing level (not applicable to RTK Float). The Ambiguity fixing le vel radio b u ttons

govern the process of the RTK engine, fixing integer ambiguities. The RTK engine uses the ambiguity fix indicator when making decisions whether or not to fix ambiguities. Low, Medium, and High correspond to the indicator's 95%, 99.5% and 99.9% states, respectively. The higher the specified confidence level, the longer the integer ambiguity search time

6. Select the Ports tab and set the following parameters for Serial C (Figure 3-17 on page 3-23):

• Input drop-down list – select desired differential

correction format.

• Period (sec) – leave as is.

• Baud rate drop-down list – select a baud rate (i.e., the

rate at which differential messages will be received from the modem).

The geodetic coordinates displayed on the Geo tab are always computed in WGS84 and have four solution types.

• Standalone – where receiver computes 3D coordinates in autonomous mode without using differential corrections.

• Code differential – where the Rover receiver computes the current relative coordinate in differential mode using only pseudo ranges.

• RTK float – where the Rover receiver computes the current relative coordinates in differential mode using both pseudo ranges and phases; however, with a float
