Timing

Features

  • Concurrent reception of GPS and GLONASS

    ・Improves robustness of the timing data thanks to concurrent reception of GPS and GLONASS
    ・Supports GPS, GLONASS, SBAS and QZSS. Galileo Ready
  • Suitable for LTE-Advanced small cellular base stations

    ・Twice the number of satellites in view than with GPS-only positioning only thanks to Multi-GNSS
    ・​Enables to output accurate and robust UTC time and 1PPS from receiving much more satellites even in deep urban canyons
    ・​Suitable for LTE-Advanced small cellular base stations
  • Easy to replace with Motorola M12M device

    ・Supports M12 binary protocol as well as identical footprint to the Motorola M12M device
  • Time Pulse Output

    Enable to output accurate and robust UTC time and 1PPS synchronized with UTC time
    ・1PPS accuracy: < 15 nsec (1σ) (@ -130 dBm)
  • One satellite tracking is enough to output precise 1PPS

  • TRAIM Function

    Detect low-integrity satellite and satellite not to use for positioning
    ・Suitable for infrastructure development which needs high integrity
  • Position Mode

    Selectable Position Mode based on use case
    ・Position Hold Mode
    ・Position Survey Mode
  • Improved Noise Tolerance

    Reduces effects of internal and external noise
    ・Active Anti-Jamming
    ・Advanced Multipath Mitigation
  • Fast TTFF

    Selectable appropriate method for fast TTFF
    ・Hot start: <5 sec (Typ.)
    ・Cold start: 35 sec (Typ.)
  • Data Output Format

    M12 Binary
  • Ready for New Positioning Systems

    Galileo E1B/E1C
    QZSS L1S
  • Embedded Flash ROM

    Suitable for long-term use backed by Furuno’s continuous support and function enhancement
