Trimble SPS780 Extreme GPS Receiver

The Trimble® SPS780 Smart GPS Antenna is the simple solution to all your site measurement and stakeout applications. The rugged smart antenna includes an integrated radio, GPS receiver, GPS antenna and battery in a single, lightweight housing designed for maximum portability, quick setup and optimal flexibility.

The SPS780 Smart GPS Antenna offers contractors an easy-to-use, wide area measurement system for a variety of site preparation and grade checking applications. It can be used as either a rover for site measurement and stakeout or as a base station for site measurement and machine control operations. As a base station, the SPS780 takes little or no setup time and only requires a single keystroke each day to start up.


  • Small, lightweight design – 1.31 kg (2.89 lb) (receiver only with battery) 3.7 kg (8.16 lb) complete system weight (Rover including controller and rod) 
  • Quick setup, high mobility base and rover receiver system ideal for small to mid size jobsites and for working on multiple jobsites on a daily or weekly basis
  • 24-channel L1/L2 GPS receiver 
  • Performs all site measurement and stakeout operations within >5 km (Max or Extreme)
  • Internal, removable, smart Li Ion battery provides up to 5.5 hrs GPS rover operation per battery. Batteries can be changed when flat, and returned to office or truck for charging leaving the receivers working in the field. 
  • Bluetooth® wireless technology for cable free, no hassle base or rover operation
  • Simple keypad with on/off key and LED indicators for power, radio and satellite tracking
  • 10 Hz update rate
  • Allows measurement from a moving platform e.g. mounted on a vehicle, boat or ATV for increased efficiency on large jobsites.
  • Base/Rover receiver interchangeability for ultimate GPS fleet flexibility
  • Unrestricted rover operation range from the base station
  • Either receiver can operate within a VRS network for base station-free rover capability
  • L2C GPS signal modernization capability for enhanced performance in tough GPS environments
