Introduction

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 existing and proposed Global Navigation Satellite Systems (GNSS) and receiver functions to help you understand and apply basic operating principles, allowing you to get the most out of your receiver. Also discussed are the principles behind surveying with Differential GPS, and using radio beacon signals as the source of corrections to locate unknown points.

GNSS Overview

Currently, the following three global navigation satellite systems (GNSS) offer line-of-site radio navigation and positioning, velocity, and time services on a global, all-weather, 24-hour scale to any user equipped with a GNSS tracking receiver on or near the Earth’s surface:

• 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 Ministry of Defense website (http://www.glonass-center.ru/frame_e.html).

• GALILEO – an upcoming global positioning system maintained and operated by Galileo Industries, a joint venture of several European space agencies working closely with the European Space Agency. Unlike GPS and GLONASS, this is a civil endeavor and is currently in the development and validation stage. For information on the status of this system, visit the Galileo Industries website (http://www.galileo-industries.net).

BR-1 Operator’s Manual

Principles of Operation

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

• Space – GPS, GLONASS, and GALILEO satellites orbit 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 GNSS receivers and the corresponding satellites 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, GLONASS, GALILEO), the receiver must lock onto at least five satellites to obtain an absolute position.

To provide fault tolerance using only GPS or only GLONASS, the receiver must lock onto a fifth satellite. Six satellites will provide fault tolerance in mixed scenarios.

P/N 7010-0796

1-3

Introduction

Calculating Differential Positions

DGPS, or Differential GPS, typically uses the measurements from two or more remote receivers to calculate the difference (corrections) between measurements, thus providing more accurate position solutions.

With DGPS, 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 is referred to as the remote receiver or rover. The reference station collects the range measurements from each GPS satellite in view and forms the differences (corrections) between the calculated distance to the satellites and the measured pseudo-ranges to the satellites.

These corrections are then built up to the industry standard (RTCM or various proprietary standards) established for transmitting differential corrections and broadcast to the remote receiver(s) using a data communication link. The remote receiver applies the transmitted DGPS corrections to its range measurements of the same satellites.

Using this 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 of the GPS.

A number of differential positioning implementations exist, including post-processing surveying, real-time kinematic surveying, maritime radio beacons, geostationary satellites (as with the OmniSTAR service), and the wide area augmentation system (WAAS) service.

The real-time kinematic (RTK) method is the most precise method of real-time surveying. RTK requires at least two receivers collecting navigation data and communication data link between the receivers. One of the receivers is usually at a known location (Base) and the other is at an unknown location (Rover). The Base receiver collects carrier phase measurements, generates RTK corrections, and sends 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, achieving an RTK accuracy of up to 1 cm horizontal and 1.5 cm vertical.

BR-1 Operator’s Manual

Principles of Operation

Essential Components for Quality Surveying

Achieving quality position results requires the following elements:

• Accuracy – The accuracy of a position primarily depends upon the satellite geometry (Geometric Dilution of Precision, or GDOP) and the measurement (ranging) errors.

– Differential positioning (DGPS and RTK) strongly mitigates

atmospheric and orbital errors, and counteracts Selective Availability (SA) signals the US Department of Defense transmits with GPS signals.

– The more satellites in view, the stronger the signal, the lower

the DOP number, the higher positioning accuracy.

• 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 distort signals, lowering the number of available satellites and adversely affecting signal reception.

• 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.

– Five or more visible satellites for only GPS or only

GLONASS; six or more satellites for mixed scenarios.

– Wide Area Augmentation Systems (WAAS, EGNOS, etc.)

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

– Current ephemerides and almanacs.

Introduction

Coastal Navigation Beacons DGPS Service

Throughout the world, a number of coastal radio beacon networks have been established to improve the accuracy of maritime navigation around harbors and critical waterways. These beacon networks provide correction information to GIS users with the proper equipment. Since beacon stations act as the known reference point, the repetitive set up, survey, and configuration of a base station has been eliminated. A beacon system provides ±3 meter accuracy

In the United States, the coastal navigation beacons are managed by the United States Coast Guard and provide differential correction service in coastal areas and much of the interior of the United States.

In other parts of the world, coastal navigation beacons modeled after the US Coast Guard system are available. Check with your local maritime authority to learn more about services available in your area. The Beacon system is provided free of charge in the United States.

• For detailed information on the coastal navigation beacon system in the United States, visit the US Coast Guard’s Navigation Center website (www.navcen.uscg.gov).

• For detailed information on the coastal navigation beacon system in other parts of the world, visit the International Association of Marine Aids to Navigation and Lighthouse Authorities website (http://www.iala-aism.org/web/index.html).

BR-1 Overview

The BR-1 is a 4-channel radio beacon receiver. Included in the system is beacon and Bluetooth. Bluetooth provides a connection with an external device such as GMS-2. This cable free connection allows for smart field work.
