Integrated GPS

Available with: SNRDS Series & SIMPAC Series

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 Altitude: -1000 m to +18,000 m Velocity: 515 m/sec maximum Acceleration: 4g (39.2 m/sec 2 ) Motional Jerk: 20m/sec3
