Trimble SPS850 Extreme GPS GLONASS L1 L2CS L5 430-450MHz Base Or Rover Receiver

Trimble SPS850 Extreme GPS

Trimble SPS850 Extreme
Flexible modular receiver for permanent base station, mobile
base station and rover operations for GPS modernization.

The Trimble® SPS850 Modular GPS Receiver sets new standards for fast
setup and flexible operation in both base station and rover

The Trimble SPS850 Receiver supports Global Positioning System (GPS)
modernization through support of L2C code, L5 GPS carrier signal, and
GLONASS protecting your investment well into the future. The new
signals will improve performance in tough satellite coverage
environments (deep cuttings, mines, trenches, landfill sites and around
tall buildings) and at longer ranges from the base station.

Modularity provides the ability to choose the appropriate GPS antenna
for the application, Zephyr Geodetic Model 2 at the base station and
the Zephyr Model 2 for the mobile units. The GPS and radio antennas can
be mounted high in permanent and semi-permanent base station
applications so that they are clear from obstructions and provide
maximum radio coverage, while the receiver is locked in a secure
environment safe from theft and environmental conditions. The choice of
radio antennas allows the customer to either attach it to the receiver
itself for mobile base station and rover applications, or use a
high gain or directional antenna for maximum range on large job

Standard System Features:

  • Integrated GPS receiver and radio
  • Internal 450 or 900 MHz radio with Transmit/Receive capability
  • 72-channel L1/L2/L2C/L5/GLONASS GPS receiver
  • OmniSTAR XP and HP service capable
  • WAAS, EGNOS & MSAS Satellite Based Augmentation (SBAS)
  • Tough housing
  • IP67 environmental rating
  • -40 °C to +65 °C (-40 °F to +149 °F) operating temperature range
  • 9V to 30V DC input power range with over-voltage protection

    station and >12 hrs as a rover with internal Transmit/Receive radio.
    (New battery operating at room temperature.)
  • Integrated display and keypad for system configuration without a
  • Integrated Bluetooth® for cable free configuration with a
    controller or Bluetooth enabled radio
  • External GPS antenna choice for base station or rover operation
  • Rubber duck antenna, or attach a high gain radio antenna for
    maximum coverage
  • Small, lightweight design – 1.65 kg (3.64 lbs) (receiver with
    internal radio and battery) 4 kg (8.82 lbs) complete system weight
    (Rover including controller and rod)
  • Permanent or semi-permanent base station, or mobile base station
  • ATV, belt, rod, supervisor’s vehicle or marine vessel mounting
    options for rover applications
  • Capable of all site measurement and stakeout operations within
    radio or cellular coverage
  • Capable of rover operation within a VRS (Virtual Reference
    Station) network
  • Easy-to-use menu system for fast configuration and status
  • Autobase for rapid and automated repeated daily base station
  • Supports IP so that it can be configured and checked remotely
    over the Internet via an Ethernet port
  • One base station receiver can broadcast corrections via multiple
    radio links. For example, broadcast corrections via an internal 450 MHz
    radio, as well as an external 900 MHz radio from the same base station

SPS850 Base Station

  • Provides unrestricted operational range for rovers and grade
    control systems
  • Base station and rover operation in a single receiver
  • Integrated Transmit/Receive radio
  • Integrated Ethernet and IP capability facilitates base station
    and receiver configuration over the Internet or via Ethernet connection
    on a computer network
  • Web-based User Interface allows for remote configuration or
