Introduction
The GMS-2Pro receiver is a single-frequency, GPS+GLONASS L1
receiver and hand-held controller built to be the most advanced,
compact, and portable receiver for the GIS surveying market. An
integrated electronic compass and digital camera make the GMS-2Pro
an all-purpose, GIS field mapping unit.
The GMS-2Pro 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 GMS-2Pro 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.
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.
GNSS Overview
Currently, the following three global navigation satellite systems
(GNSS) offer line-of-site radio navigation and positioning, velocity,
