GPS Antenna and Receiver for Time/Date Applications

The Videotek® GPS-3903-2 standalone GPS antenna and receiver allows the VSG4-TCG time code generator to provide outputs with good accuracy, and can also be used as a lower cost, lower precision standalone GPS antenna and receiver for the VSG-4MTG master timing generator and VSG-4TSG test signal generator. The global positioning system (GPS) gives the user the most accurate source of time used in the public domain — a system of 24 satellites that provides complete coverage in any part of the world with information on time and position. This makes the VSG4-xxx devices independent from telephone or radio receiver standards.

PERFORMANCE
General L1 frequency, C/A code (SPS), 12-channel continuous tracking receiver
Update Rate 1 Hz (TSIP,NMEA, or TAIP)
Accuracy Position - Horizontal: <5 m (50%), <8 m (90%)
Position - Altitude: <10 m (50%), <16 m (90%)
Velocity: 0.06 m/sec
1 PPS (static) ±50 nanoseconds
DGPD Accuracy Position: 2 m CEP (50%)
Velocity: 0.05 m/sec (1 sigma)
Time: ±500 nanoseconds (nominal)
Acquisition Cold start: <50 sec (50%) <84 sec 90%
Warm start: <38 sec (50%) <42 sec 90%
Hot start: <10 sec (50%) <13 sec 90%
Cold start requires no initialization. Warm start implies last position, time and almanac are saved by back-up power. Hot start implies ephemeris also saved.
