Features

Applicable receivers:  BD990 | BD992 | BD992-INS | BX992

The following features are applicable to these receivers.

Technical specifications

  • Trimble Maxwell™ 7 technology

  • On-board Advanced MEMS inertial sensors (BD992-INS and BX992 only)

  • 336 tracking channels:

    • GPS: L1 C/A, L1C, L2E, L2C, L5

    • BeiDou: B1, B1C, B2, B2A, B2B, B3

    • GLONASS: L1 and L2 C/A, L3 CDMA

    • Galileo: E1, E5A, E5B, E5AltBOC, E6

    • NavIC: L5

    • QZSS: L1 C/A, L1C, L1 SAIF, L2C, L5, LEX, L6/LEX

    • SBAS: L1 C/A, L5

    • MSS L-Band: OmniSTAR, Trimble RTX

  • High precision multiple correlator for GNSS pseudorange measurements

  • Trimble EVEREST™ Plus multipath mitigation

  • Advanced RF Spectrum Monitoring and Analysis

  • Unfiltered, unsmoothed pseudorange measurement data for low noise, low multipath error, low time domain correlation and high dynamic response

  • Very low noise GNSS carrier phase measurements with <1 mm precision in a 1 Hz bandwidth

  • Proven Trimble low elevation tracking technology

  • Reference outputs/inputs: CMR, CMR+™, sCMRx, RTCM 2.2, 2.3, 2.4, 3.0, 3.1, 3.2, 3.3.

  • The functionality to input or output any of these corrections depends on the installed options.

    • Different manufacturers may have established different packet structures for their correction messages. Thus, Trimble OEM GNSS receivers may not receive corrections from other manufacturers' receivers, and other manufacturers' receivers may not be able to receive corrections from Trimble OEM GNSS receivers.

  • Navigation outputs:

    • ASCII: NMEA-0183: GBS; GGA; GLL; GNS; GRS; GSA; GST; GSV; HDT; LLQ; AVR; GDP; DTM; BPQ; GGK; PJK; PJT; VGK; VHD; RMC; ROT; VTG; ZDA.

    • Binary: Trimble GSOF, NMEA 2000

    NOTE – Galileo support is developed under a license of the European Union and the European Space Agency.

    NOTE – There is no public GLONASS L3 CDMA ICD. The current capability in the receivers is based on publicly available information. As such, Trimble cannot guarantee that these receivers will be fully compatible.

  • 1 pulse-per-second (1PPS) output

  • Event Marker Input support

  • Supports Fault Detection and Exclusion (FDE), Receiver Autonomous Integrity Monitoring (RAIM)
