Introduction

The HiPer II receiver is a multi-frequency GNSS receiver, built to be the most advanced and compact receiver of its kind for the surveying and construction markets.

The HiPer II can receive and process GNSS signals on the L1 and L2 frequencies of both the GPS and GLONASS satellite navigation systems. This multi-frequency and multi-constellation capability improves the accuracy and reliability of the survey points and positions that are produced by the HiPer II system, especially under difficult jobsite conditions. The HiPer II possesses several other features, including advanced multipath mitigation, which helps provide reception under-canopy and in low signal strength areas. The receiver provides the functionality, accuracy, availability, and integrity needed for fast and easy data collection.

Introduction

Principles of Operation

Surveying with a professional-grade GNSS receiver can provide users with accurate and precise positioning; a fundamental requirement for any surveying project.

This section gives an overview of existing and proposed Global Navigation Satellite Systems (GNSS) and receiver functions so that basic operating principles can be applied.

GNSS Overview

Currently, two Global Navigation Satellite Systems (GNSS) offer line-of-sight radio navigation, positioning, and timing services on a global, all-weather scale to any user equipped with a GNSS tracking receiver:

• GPS - the Global Positioning System maintained and operated by the United States Department of Defense. For information on the status of this system, visit the US Naval Observatory website (http://tycho.usno.navy.mil/) or the US Coast Guard website (http://www.navcen.uscg.gov/).

• GLONASS - the GLobal NAvigation Satellite System maintained and operated by the Russian Federation Ministry of Defense. For information on the status of this system, visit the Coordinational Scientific Information Center website (http://www.glonassianc.rsa.ru/).

Despite the numerous technical differences in the implementation of these systems, both satellite positioning systems have three essential components:

• Space - GPS and GLONASS satellites orbit approximately 12,000 nautical miles above Earth, and are equipped with an atomic clock and a radio. These satellites broadcast ranging signals and various digital information (ephemerides, almanacs, time and frequency corrections, and so forth).

• Control - Ground stations located around the Earth that monitor the satellites and upload data, including clock corrections and

1-2

HiPer II Operator’s Manual

Principles of Operation

new ephemerides (satellite positions as a function of time), to ensure the satellites transmit data properly.

• User - The community and military that use GNSS receivers to calculate positions.

Calculating Absolute Positions

When calculating an absolute position, a stationary or moving receiver determines its three-dimensional position with respect to the origin of an Earth-Center Earth-Fixed coordinate system. To calculate this position, the receiver measures the distance (called pseudoranges) between it and at least four satellites. The measured pseudoranges are corrected for clock differences (receiver and satellites) and signal propagation delays due to atmospheric effects. The positions of the satellites are computed from the ephemeris data transmitted to the receiver in navigation messages. When using a single satellite system, the minimum number of satellites needed to compute a position is four. In a mixed satellite scenario (GPS and GLONASS), the receiver must lock onto five or more satellites to account for the different time scales used in these systems and to obtain an absolute position.

Calculating Differential Positions

DGPS, or Differential GPS, is a relative positioning technique where the measurements from two or more remote receivers are combined and processed using sophisticated algorithms to calculate the receivers' relative coordinates with high accuracy. DGPS accommodates various implementation techniques that can be classified according to the following criteria:

• The type of GNSS measurements used, either code-phase differential measurements or carrier-phase differential measurements

• If real-time or post-mission results required. Real-time applications can be further divided according to the source of differential data and communication link used.

With DGPS in its most traditional approach, one receiver is placed at a known surveyed location and is referred to as the reference receiver or base station. Another receiver is placed at an unknown location and

P/N 7010-0982

1-3

Introduction

is referred to as the remote receiver or rover. The reference station collects the code-phase and carrier-phase measurements from each GNSS satellite in view.

• For real-time applications, these satellite measurements and the reference station coordinates are then combined to form industry

standard RTCM

messages that are broadcast to the remote receiver(s) using a data communication link. The remote receiver applies the transmitted measurement information to its observed measurements of the same satellites.

• For post-mission applications, the simultaneous measurements from reference and rover stations are recorded to the receiver's memory card (not sent over a communication link). Later, the data is downloaded to a computer, combined, and processed. Using this post-processing technique, the spatially correlated errors - such as satellite orbital errors, ionospheric errors and tropospheric errors - can be significantly reduced, thus improving the position solution accuracy. This is particularly true when the remote receiver is stationary.

Other differential positioning methods and systems also exist, including, maritime radio beacons, commercial geostationary satellites (as with the OmniSTAR service) and satellite based augmentation systems (WAAS, EGNOS, MSAS). For use of these other systems additional hardware and/or subscription fees may be required that are separate from the HiPer II system.

The Real-time Kinematic (RTK) method is the most common method of precision real-time surveying. RTK operation requires at least two receivers collecting simultaneous GNSS data and a reliable lowlatency communication link between the receivers. As with DGPS

1. [RTCM FOOTNOTE] The Radio Technical Commission for Maritime

Services (RTCM) defines global standards for communication messages and protocols that are used in the GNSS positioning industry. In support of this standards-based approach, Topcon recommends use

of the latest RTCM message formats (v3 or greater) for all RTK and DGPS communication needs. Several legacy correction message

formats are also provided by Topcon GNSS products in order to support interoperability with older GNSS systems, but their use is now deprecated.

1-4

HiPer II Operator’s Manual

Principles of Operation

described earlier, one of the receivers is usually at a known location (Base) and the other is at an unknown location (Rover). The Base receiver collects precise carrier phase measurements, generates RTK corrections and transmits this data to the Rover receiver. The Rover processes this transmitted data with its own carrier phase observations to compute its relative position with high accuracy, thus achieving an RTK accuracy of up to 10mm horizontal and 15mm vertical.

Essential Components for Quality Surveying

Achieving quality positioning results from the HiPer II requires an understanding of the following elements:

• Accuracy - The accuracy of a position that is delivered by a GNSS receiver primarily depends upon the observed satellite geometry (Geometric Dilution of Precision, or GDOP) and the measurement (ranging) errors.

– Differential positioning techniques (DGPS and RTK) can be

used to almost completely remove all major GNSS error sources, such as atmospheric and orbital errors.

– The more satellites that are in view, the stronger the signal,

the lower the GDOP number will be, leading to the highest positioning accuracy. For DGPS and RTK operations, it is important to consider that the GDOP is dependent on the number of common satellites in view at both the Base and the Remote receivers.

– The quality of observed measurements can also affect

accuracy, and for this reason Topcon GNSS products use sophisticated and patented techniques to produce highly precise measurements. However, these measurements can still be adversely affected by nearby natural and man-made objects that block, interrupt, reflect, or partially obscure satellite signals.

• Availability -

While a low number of satellites may adversely

affect accuracy, if very few satellites are visible this may result in no position being available at all. A minimum of 4 GPS or 4

P/N 7010-0982

1-5

Introduction

GLONASS, or 5 GPS+GLONASS (mixed) satellites must be visible at all times.

• Integrity - Fault tolerance and redundancy allow a position solution to have greater integrity, increasing its reliability for the user. Several factors combine to provide fault tolerance, including:

– Receiver Autonomous Integrity Monitoring (RAIM) detects

faulty GNSS satellites and removes them from the position calculation. This is a built-in and valuable feature of the HiPer II receiver.

– Five or more visible satellites for only GPS or only

GLONASS; six or more satellites for a mixed scenario. As the total number of satellites increases, so does the measurement redundancy and the inherent reliability of the position.

– Satellite Based Augmentation Systems (WAAS, EGNOS,

and so on) creates and transmit, along with DGPS corrections, data integrity information (for example, satellite health warnings).

– Current ephemerides and almanacs.

Principles of Operation

HiPer II Receiver

When power is turned on and the receiver self-test completes, the receiver's 72 channels initialize and will begin tracking all visible satellites. Each of the receiver's channels can be used to track any one of the available GPS or GLONASS signals. The number of channels on the HiPer II allows the receiver to track all visible global positioning satellites at any time and location.

The internal micro-centered GNSS antenna delivers a stable and lownoise signal to the receiver sub-system. This wide-band signal is down-converted, filtered, digitized, and assigned to different channels. The receiver processor controls the process of signal tracking.

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

Once the receiver successfully locks on to four or more satellites, its absolute position in WGS84, along with the time offset between the receiver clock and GPS time are computed. This information and the measurement data can be optionally stored on the SD/SDHC card, later downloaded onto a computer, and then processed using a postprocessing software package. Even when the receiver operates in RTK mode, raw data measurements can still be recorded to the receiver's storage card; this allows the operator to perform postmission verification of real-time results obtained in the field.

The HiPer II comes in one of the following configurations:

• with a Digital UHF TX/RX radio modem

• with a Digital UHF TX/RX radio modem and a GSM/GPRS module

• with a Digital UHF TX/RX radio modem and a CDMA module (for US customers)

Principles of Operation

Inserting and Removing the Battery

• First, before removing the battery, always turn off power to the instrument. If the battery is removed while the power is switched on, uncontrolled system shutdown will occur and file data may be lost as a result.

• When inserting or removing the battery, make sure that moisture, dust, or other foreign particles do not come in contact with the inside of the instrument.

• Remove batteries from the surveying instrument or charger before placing into storage.

• Store the battery in a dry room where the temperature is within the following ranges. For long-term storage, the battery should be charged at least once every six months.

Table 1-1. Battery Storage Time

Storage Period Temperature

1 week or less -20°C to +50°C

1 week to 1 month -20°C to +45°C

1 month to 6 months -20°C to +40°C

6 months to 1 year -20°C to +35°C

• The BDC58 uses the latest advances in high density lithium-ion battery technology. However, like all batteries, it still generates power using a chemical reaction and as a result, has a limited lifetime. Even when the battery is in storage and not used for long periods, the battery capacity deteriorates with the passage of time. This may result in the operating time of the battery shortening despite having been charged correctly. In this event, a new battery is required.

Collecting Almanacs and Ephemerides

Each satellite broadcasts a navigation message that includes the ephemeris parameters of the satellite, the almanac, and various other information. The ephemeris parameters describe the orbital motion of the tracked satellite and are used to predict its location/trajectory. The almanac gives the approximate orbit (course) for the transmitting satellite as well as all other satellites in the same system.

• 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.

If the receiver has an almanac, the time needed to search for and lock onto satellite signals is considerably reduced.

P/N 7010-0982

2-7

• Enable Solutions – Select solutions used in position computation.

– Standalone – where the 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 carrier phase ambiguity fixing in differential mode.

HiPer II Receiver Setup

After receiver survey configuration, set up each receiver, measure its height, and begin surveying. The LED Display Panel provides quick access for: logging data and viewing general data logging and satellite information during a survey.

Receiver Setup

A typical GPS survey system consists of a Base station set up over a known point and a Rover receiver set up as a mobile data collector. After setting up the Base and Rover receivers, the antenna height must be measured.

Before collecting data, make sure the Base and Rover receivers contain a current almanac and current ephemeris data (see “Collecting Almanacs and Ephemerides” on page 2-7).

Step 1: Set up the Receivers

The Base station must be set up, logging data, and transmitting data before setting up the Rover receiver. Receiver setup for either postprocessing or RTK surveys is the same.

 Set up the Base station and its components.

See “To set up the Base receiver” on page 4-1 for details.

 Set up the Rover receiver.

See “To set up the Rover receiver” on page 4-3 for details.

To set up the Base receiver (Figure 4-1):

1. Install a tripod over a known control point.

2. Secure the universal tribrach onto the tripod. Place the tribrach adapter onto the tribrach and tighten the screws.

HiPer II Receiver Setup

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, 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.

The surveying point that GPS/GLONASS to measure satellite systems is called the “Phase Center” of the antenna. The antenna Phase Center is analogous to the calibrated point to which a distance meter measures inside of a prism; i.e. it cannot be directly measured to in the field. For precision Topcon GPS/GLONASS antennas − such as the one inside the HiPer II − the antenna Phase Center must be modeled using a detailed calibration in order to achieved optimal survey results. This model information consists of phase center offset (PCO) and phase center variation (PCV) components, and is applied internally by field software such as TopSURV for RTK operations,

and by Topcon Tools software for post-mission operations

1. This antenna calibration information (PCO and PCV data) does not

need to be entered in the field.

4-4

HiPer II Operator’s Manual

Receiver Setup

The only information that must be supplied from field observations when using Hiper II is i) the measured instrument height, and ii) the measurement method used. The Topcon field and office software will

automatically make all antenna Phase Center adjustments

that are

necessary to deliver properly referenced marker coordinates.

1. Measure the antenna height above the control point or marker,

either the slant height or the vertical height. You may either measure the vertical height to the Antenna Reference Point (ARP) located at the bottom of the HiPer II, or measure the slant height to the Slant Height Measurement Mark (SHMM) on the side of the enclosure (Figure 4-3 on page 4-6).

2. Record the antenna height, points name, and start time in the field

notes.

1. Advanced users may choose to configure the applied Phase Center model that is used for the Hiper II, and this may be done using Topcon application software such as TopSURV and Topcon Tools. This additional step is optional since Topcon software automatically contains antenna Phase Center models for all Topcon products, including the Hiper II. Instead of Topcon's supplied default Phase Center model for HiPer II, alternate or updated Phase Center models (with PCO and PCV data) may be obtained from various government or private calibration services. The most widely recognized of these services are the U.S. National Geodetic Survey (NGS), the International GNSS Service (IGS), and Geo++ GmbH of Germany. The default Phase Center models supplied with Topcon products are typically based on absolute calibration models from NGS.

Static Surveying for Base Stations

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

• 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 10 kilometers (approximately 6 miles). For baselines of 10 kilometers or greater, use of dual-frequency receivers is recommended.

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

After the survey completes, data the receivers collect can be downloaded onto a computer and processed using post-processing software.

Receiver and File Maintenance

When post-processing the data after completing a survey, the data in the receiver’s memory needs to be downloaded to a computer. Downloading and deleting files prepares the receiver’s memory for the next survey. Occasionally, the receiver’s NVRAM may need to be cleared to eliminate communication or tracking problems.

As project expectations expand, the receiver’s OAF may need to be updated to provide expanded operation and functionality. The various boards inside the receiver (GPS, power, modem, and Bluetooth) require firmware to properly operate and provide appropriate functionality. As Topcon releases firmware updates, loading these updates into the receiver will ensure the receiver operates at its full potential.

Downloading Files to a Computer

Downloading Files via TRU

Managing Receiver Memory

When using the receiver in static or dynamic applications, the user may need to know the amount of memory the receiver’s log file occupies. The specific memory size depends on the type of data being recorded. Use the formulas below to compute the approximate size of the receiver’s log files. These equations are based on the default set of messages.

• SS – the estimated size of one epoch of raw data in the receiver’s log file (expressed in bytes).

• N – the number of observed satellites per epoch.

When recording only L1 data:

SS = 183 + 22*N

When recording L1 and L2 data:

SS = 230 + 44*N

Managing Receiver Options

The Option Authorization File (OAF) enables certain functions, features, and options in the receiver, such as the following:

• The type of signal (L1, L1/L2, and so on) the receiver processes.

• The amount of data the receiver stores in the memory.

• The rate at which data is transmitted or received.

Clearing the NVRAM

The receiver’s Non-volatile Random Access Memory (NVRAM) holds data required for satellite tracking, such as ephemeris data and receiver position. The NVRAM also keeps the current receiver’s settings, such as active antenna input, elevation masks and recording interval, and information about the receiver’s internal file system.

Even though clearing the NVRAM is not a common (nor normally a recommended) operation, there are times when clearing the NVRAM

5-8

HiPer II Operator’s Manual

Clearing the NVRAM

can eliminate communication or tracking problems. Clearing the receiver’s NVRAM can be interpreted as a “soft boot” in the computer.

After clearing the NVRAM, the receiver requires time to collect new ephemerides and almanacs (around 15 minutes).

Clearing the receiver’s NVRAM will not delete any files already recorded in the receiver’s memory. However, it will reset the receiver to factory default values.

In addition, the NVRAM keeps information about the receiver file system.
