Details

Trimble R8 Model 4 GNSS Receiver
The receiver incorporates a GNSS antenna, receiver, internal radio with a transmit option or an internal GSM module, and a battery in a rugged light-weight unit that is ideally suited as an all-onthe-pole RTK rover. Three LEDs allow you to monitor the satellite tracking, radio reception, data logging status, and power. Bluetooth wirelesstechnology provides cable-free communications between receiver and controller.
  • The circuitry in the Trimble R8 Model 4 GNSS receiver provides up to 440 channels for satellite tracking, and supports logging raw GNSS observables to the internal receiver memory or to a handheld controller for postprocessed applications.
The receiver is available as a standalone rover, base station, or as part of the GNSS Total Station® system, offering maximum versatility in the system configuration to meet your specific requirements.

The receivers provide the following features:
  • Future-proof Trimble 360 technology (Trimble R8 Model 4), which includes advanced Trimble Maxwell 6 Custom Survey GNSS chips with 440 channels and allows the receiver to track the following:
    • GPS: L1 C/A, L1C, L2C, L2E, L5
    • GLONASS: L1 C/A, L1P, L2 C/A, L2P, L3
    • Galileo: E1, E5A, E5B
    • BeiDou (COMPASS): B1, B2
    • SBAS: QZSS, WAAS, EGNOS, GAGAS
  • Centimeter-accuracy, real-time positioning with RTK/OTF data, up to 20 Hz position updates (R8 Model 4) or up to 10 Hz (R6 Model 4 and R4 Model 3)
  • Submeter-accuracy, real-time positioning using pseudorange corrections
  • Automatic OTF (on-the-fly) initialization while moving
  • Single Lithium-ion rechargeable battery
  • Cable-free Bluetooth communications with Trimble controllers
  • Two RS-232 serial ports for:
    • Trimble Format (CMR, CMR+™ and CMRx) input and output
    • RTCM SC-104 input and output (RTCM 2.1, 2.3, 3.0, 3.1)
    • 23 NMEA outputs
    • GSOF, RT17, and RT27 outputs
    • Supports BINEX and smoothed carrier
  • One TNC radio antenna connector
  • Internal memory for data storage
