Introduction
The GR-3 receiver is a multi-frequency, GPS+ 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.
The GR-3 can receive and processes multiple signal types (including
the latest GPS L2C, GPS L5, GLONASS C/A L2, and GALILEO
signals) improving the accuracy and reliability of the survey points
and positions, especially under difficult jobsite conditions. The multi-
frequency and GPS+ features of the receiver combine to provide a
positioning system accurate for any survey. Several other features,
including multipath mitigation, provide under-canopy and low signal
strength reception. The receiver provides the functionality, accuracy,
availability, and integrity needed for fast and easy data collection.
