Introduction
The GRX1 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

construction
hydrographic and any use reasonably related to the foregoing.
The GRX1 can receive and processes multiple signal types ( including the latest GPS L1, L2, C/A,
L2C GLONASS L1, L2, C/A signals ) improving the accuracy and reliability of the survey points
and positions, especially under difficult jobsite conditions.
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.
Principles of Operation
Surveying with the right GPS receiver can provide users accurate and precise positioning, a
requirement for any surveying project.
