Trimble SPS850 Extreme Receiver
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 applications.
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 sites.

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) compatible
  • 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
  • Long life integrated battery. >10 hrs operation as a base 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 controller
  • 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 versatility
  • 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 checking
  • Autobase for rapid and automated repeated daily base station setups
  • 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 receiver

SPS850 Base Station Features:

  • 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 troubleshooting
