What is GPS?

GPS (Global Positioning System) is a space-based satellite navigation system that
provides location and time information anywhere on the earth. It was developed by the
U.S. Department of Defense as a military system. It receives signals from 3 or more of
about 30 GPS satellites flying at an altitude of about 20,000 km, and displays the current
position (latitude, longitude, altitude) within an accuracy of several meters. In addition,
GPS can receive the exact time from the satellite's onboard atomic clock.
The transceiver is equipped with a high-sensitivity 66-channel GPS antenna supporting
QZSS (Quasi-Zenith Satellite System) which shortens measuring time and improves the
accuracy of the location information.
