Full-featured, low-cost, embedded GPS Timing Receiver
Caratteristiche
  • Multi-GNSS (GPS, GLONASS, Beidou & Galileo ready)
  • High sensitivity
  • Assisted GPS (A-GPS)
  • Extended Temperature range (-40°C to +85°C)
  • Timing pulse synchronized to within 15 nanoseconds (one sigma) of GNSS/UTC
Produttore:: Trimble


General L1 (1575.42 MHz) Frequency, C/A Code, 12-channel, parallel-tracking receiver, DSP-based
Update Rate TSIP @ 1 Hz; NMEA @ 1 HZ
Accuracy
    - Horizontal Position: <6 meters (50%), <9 meters (90%)
    - Altitude Position: <11 meters (50%), <18 meters (90%)
    - Velocity: 0.06 m/sec
    - PPS: within 15 ns to GPS/UTC (1 Sigma) <5 ns with quantization error removed
Acquisition
    - Reacquisition: <2 sec. (90%)
    - Hot Start: <14 sec (50%), <18 sec (90%)
    - Warm Start: <41 sec (50%), <45 sec (90%)
    - Cold Start: <46 sec (50%), <50 sec (90%)
Cold start requires no initialization. Warm start implies last position, time and almanac are saved by backup power. Hot start implies ephemeris also saved. Hot and Warm are shown for comparison purposes and are not used in timing applications.
