Global Positioning System
The United States Government developed the GPS navigation
system. It is a satellite-based radio navigation aid that provides
global, all-weather, precise navigation and timing capability to
users 24 hours a day.
GPS antennas must have line-of-sight access to the transmitting
satellites. Any structure that interferes with, or blocks, the view of
the satellites disrupts the reception of the signals, and may
adversely impact the timing performance of a receiver.
The TimeSource 2500 optimizes timing performance during
frequent GPS outages by anticipating the outages, and
compensating for them with advanced local oscillator and holdover
technology. BesTime-generated predictor values are used to bridge
GPS outage periods and enhance holdover performance.
