Introduction
The GR-5 receiver is a multi-frequency, GNSS receiver built to be the
most advanced and compact receiver for the surveying market. The
receiver is a multi-function, multi-purpose receiver 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.
Using a full wave antenna, the GR-5 can receive and processes
multiple signal types, including the latest GPS L2C and GLONASS
C/A L2, GPS L5 and GALILEO1signals. Driven by the augmented
Paradigm™ G3 chip, the board provides 216 universal channels and
up to 100 Hz position and measurement update rates.
GNSS tracking capabilities, dual-frequency RTK, SBAS
functionality, extensive communication capabilities, removable
memory for files combine to provide a positioning system efficient,
secure, and appropriate for any survey.
Several other unique features, including multipath mitigation,
adjustable phase-locked loop (PLL) and delay-locked loop (DLL)
parameters, offer a reliable and versatile reception of weak signals
even in degraded signal environments. The receiver provides the
functionality, availability, and integrity.
1. The GR-5 tracks the GIOVE-A and GIOVE-B test satellites. The
signals from these satellites are used for signal evaluation and test
purposes only.

Principles of Operation
P/N 7010-1004 1-3
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)1offer
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.glonass-
ianc.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).
1. GALILEO navigation satellite system currently being built by the
European Union (EU) and European Space Agency (ESA).

Introduction
GR-5 Operator’s Manual
1-4
• 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 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 pseudo-
ranges) between it and at least four satellites. The measured pseudo-
ranges 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.
Essential Components for Quality Surveying
Achieving quality positioning results from the GR-5 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
