Performance Specifications
|
| General
| L1 frequency, C/A code (SPS), 8-channel, continuous tracking
receiver, 32 correlators |
| Update rate
| TSIP @ 1 Hz; NMEA @ 1 Hz |
| Accuracy
| Position: 25 m CEP (50%) without SA Velocity: 0.1 m/sec without
SA Time: ±500 nano-seconds (nominal) |
| DGPS accuracy
| Position: 2 m CEP (50%) Velocity: 0.05 m/sec Time: ±500
nano-seconds (nominal) |
| Acquisition (typical)
| Cold start: <2 minutes (90%) Warm start: <45 seconds
(90%) Hot start: <20 seconds (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. |
| Reacquisition after signal loss
| < 2 seconds (90%) |
| Dynamics
