Introduction

Overview

Topcon Positioning System’s HiPer Lite and HiPer Lite+ receivers are dual-frequency, GPS+ receivers built to be the most advanced and compact receiver for the surveying market. The HiPer Lite and HiPer Lite+ 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 Lite and HiPer Lite+ can receive and process both L1 and L2 signals, improving the accuracy of your survey points and positions. The dual-frequency and GPS+ features of HiPer Lite and HiPer Lite+ combine 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 under­canopy and low signal strength reception. The receivers pro vide the functionality , accuracy, availability, and integrity needed for fast and easy data collection.

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
Topcon HiPer Lite and HiPer Lite+ Operator’s Manual
Page 19
Principles of Operation
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 the current status of the GPS constellation, visit http://tycho.usno.navy.mil/ or http://www.navcen.uscg.gov/. For GLONASS, visit http://www.glonass-center.ru/frame.html.
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.).
• Control – Ground stations located around the Earth that
monitor the satellites and upload data, including clock corrections and new ephemerides (satellite positions as a function of time), to ensure the satellites transmit data properly.
• User – The community and military that use GPS/
GLONASS receivers and the corresponding satellites to calculate positions.
P/N 7010-0557 www.topconpositioning.com
1-3
Page 20
Introduction
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 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, receiver’s must lock onto at least five satellites to obtain an absolute position.
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).
1-4
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.
• 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.
Topcon HiPer Lite and HiPer Lite+ Operator’s Manual
Page 21
Principles of Operation
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.
–Current ephemerides and almanacs. –Several algorithms to detect and correct faulty
information.

Introduction
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 20 channels initialize and begin tracking visible GPS 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 allo ws the recei ver to track all visible GPS satellites at any time and location. The GPS antenna receives the different signals for processing.
An internal GPS antenna equipped with a 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.
1-6
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” and compute the receiver’s coordinates (in WGS-84) and time. 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

Features inside the receiver casing are described in the following sections.
GPS+ Antenna
An internal, micro-strip antenna capable of receiving GPS L1/L2 signals and GLONASS L1/L2 signals.
Bluetooth Module
A combination of software and hardware technology that makes the HiPer Lite and HiPer Lite+ mobile, wireless, GPS+ receivers that support a point-to-point serial profile. As such, the HiPer Lite/HiPer Lite+ can transfer and synchronize files between the receiver and any other Bluetooth wireless technology device that supports serial profile, including portable handheld devices and external controllers, Bluetooth adapters for PC-USB/RS ports, mobile computers and phones, IPAQs, PCMCA-to­Bluetooth adapters, etc.
1-12
With Bluetooth wireless technology, the receiver’s reception and transmission distance is 10 meters (32 feet) for interior projects and 30–50 meters (98–164 feet) for exterior projects.
The Bluetooth module’s processor and firmware are independent of the receiver card and power board.
Radio Modem
The receiver incorporates an internal, spread spectrum, 915 MHz modem for receiving data from a Base station or transmitting data to a Rover station. The Base station’s modem transmits the carrier phase and code measurements along with the reference station information (i.e., location) to the Rover station modem.
Topcon HiPer Lite and HiPer Lite+ Operator’s Manual
Page 29
Getting Acquainted
The internal radio modem comes with a number of preset channels programmed at TPS. Complete information regarding the radio system can also be found in the radio modem’s 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).

Powering the Receiver
3. Leave overnight. A nine-hour charge cycle will charge the batteries about 90%. A ten-hour charge cycle will fully charge the receiver. The internal batteries can not be overcharged.
The speed of the charge depends on the Power and Charger settings on the Receiver Configuration screen, and whether the receiver is turned off or on. See “Power Management” on page 2-5 for 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 (Figure 2-1 on page 2-4). External batteries allows you to continue using the receiver in case the internal batteries are discharged and requires the following:
• a 12 V, 2.3 A*h battery
• a 2.3 A*h battery clip-to-SAE cable
• an SAE-to-Power Plug cable
NOTICE
NOTICE
When the receiver uses external batteries, set the charger mode to Off. Otherwise, the external batteries will also charge 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.

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 closes the current log file. If data logging is off, pressing FN opens a new log file.
• AFRM – If AFRM radio button has been selected, pressing
FN enables this mode. If AFRM has been enabled, pressing FN disables 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.
2-26
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.
• 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

The receiver’s memory holds up to 512 files.
• Files (remain) – specifies the number of files left for the
receiver to create in AFRM.

• Automatically remove old files – when no free memory is
available to log data, automatically remo ves the earliest log f ile. If this parameter is enabled, your receiver will erase the file with the earliest file creation time/date. AFRM must be enabled to use this FIFO (First-In, First-Out) feature.
The default value is off (disabled).
FN Key Mode parameter
Use these two radio buttons to program how the receiver will react when pressing the FN key.
• LED blink mode switch – pressing FN will toggle between
the MINTER’s normal/extended information modes and start/stop data recording of Static survey.
FN pressed for less than 1 second: changes the information mode (Normal or Extended Information (EI) Modes).

FN pressed for 1 to 5 seconds: starts or stops data recording (Static post-processing mode).
• Occupation mode switch – pressing FN (less than one
second) will insert into the corresponding log file a message indicating that the survey type has been changed from static to kinematic, or vice versa. If the REC LED blinks green, the current mode is dynamic, if it blinks orange, the current mode is static. For more details, see Table 4-1 on page 4-5, and refer to the MINTER User’s Manual and PC-CDU User’s Manu al .

Collecting Almanacs

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.
3. Wait for about 15 minutes while the receiver collects almanac data from the satellites.
NOTICE
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.

Setup and Survey
This chapter describes:
• Receiver setup
• RTK Base station setup
• RTK Rover setup
• Basic surveying with the HiPer Lite or HiPer Lite+ receiver
The HiPer Lite and HiPer Lite+ packages use one receiver as the Base station and the other as the Rover station.

Receiver Setup

To set up the receivers, you must:
1. Configure the receivers as shown in Chapter 2.
2. Set up the Base and Rover stations. See “Step 1: Set up the Receiver” on page 3-2.
3. Measure the antenna height. See “Step 2: Measure Antenna Height” on page 3-2 for internal antennas.
4. Begin collecting data. See “Step 3: Collect Data” on page 3-4.
All receivers include an internal, micro-strip antenna able to capture L1/L2 signals from GPS and GLON ASS satellites.

Setup and Survey

Step 1: Set up the Receiver

This section assumes the receiver has been configured 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.

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.
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:
3-2
• 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 Lite and HiPer Lite+ Operator’s Manual
Page 83
Receiver Setup
1. Measure the antenna height above the point or marker. Figure 3-1 illustrates the antenna offsets. (See Figure 1-5
on page 1-17 and Figure 1-7 on page 1-19 for the exact SHMM location.)
30.50mm
Figure 3-1. HiPer Lite and HiPer Lite+ Antenna Offsets

ARP
77.75mm
• SHMM to ARP vertical offset = 30.50mm
• SHMM to ARP horizontal offset = 77.75mm
Table 3-1gives the offset values for the receivers.
Table 3-1. Antenna Offset Values for Receiver Options
To L1 Phase Center To L2 Phase Center
Up 106.1mm 95.7mm
The 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
3-3
P/N 7010-0557 www.topconpositioning.com
Page 84
Setup and Survey
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 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.

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.

Surveying with the Receiver
Your receiver can be used to perform the following types of surveying:
• Static
• Kinematic
• Real-time kinematic (RTK)

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 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 a common 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
P/N 7010-0557 www.topconpositioning.com
3-5
Page 86
Setup and Survey
• 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 of 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 single­frequency receivers over long baselines or during ionospheric storms. Secondly, dual-frequency receivers need far less observation time to reach the desired accuracy requirement.
3-6
After the survey completes, data the receivers collect can be downloaded onto a computer and processed using post­processing software (for example, Topcon Tools).
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.

Kinematic (Stop and Go) Survey

In a kinematic, stop and go, survey, the stationary receiver (Base station) is set up over a point, such as a survey monument. The receiver continually tracks the satellites and logs the raw data into its memory. The rover receiver is set up over a 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.

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 surve y many more points compared to the other methods available.

5. Click the Rover tab and set the desired Positioning Mode (Figure 3-11).
Adjust the following RTK Parameters settings:
• Under RTK mode in the RTK Parameters section, choose either Extrapolation for RTK float (kinematic) or Delay for RTK fixed (static).

–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 RTK 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 Level radio buttons 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. Click the Ports tab and set the following parameters for
Serial C (Figure 3-12 on page 3-18):
Input drop-down list – select the 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 transmitted from modem to receiver).

8. Click OK to close the Receiver Configuration screen.
9. On the main screen (Figure 3-13), check the LQ field to ensure the receiver obtains differential corrections. Usually , the recei ver wil l start to output the coordinates of the antenna’s phase center along with the solution type within 10–30 seconds. However, spread spectrum radios may take as long as 60 seconds to synchronize.

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 solution, the phase ambiguity is not a fixed integer number and the “float” estimate is used instead.
• RTK fixed – where the Rover receiver computes
current relative coordinates, with ambiguity fixing, in differential mode.
The LQ field reflects the status of the received differential messages and contains the following information:
• Data link quality in percentage
• Time (in seconds) elapsed since the last received
message
• Total number of received correct messages (dependent
on the message type received)
• Total number of received corrupt messages (dependent
on the message type received)
If the receiver is not (for some reason) receiving dif ferential corrections, or if none of the ports has been configured to receive differential corrections, the LQ field will either be empty or it will look like this: 100%(999,0000,0000).
