Trimble Site Positioning receivers are scalable to meet the accuracy requirements of specific tasks and fit your budget. Trimble offers GNSS (Global Navigation Satellite System) receivers both in integrated and modular forms. With integrated Trimble 360 degree receiver technology, the SPS985 GNSS smart antenna and the SPS855 modular receiver can “see” more GNSS constellations and signals than traditional GPS’s, so you can expect greater accuracy in more challenging conditions such as under tree canopy and in urban areas. That also means more uptime using the system and more productivity for your field crews.

GNSS Receivers are ideal for:

  • Larger jobsites
  • Tasks where accuracy requirements are 8 millimeters (0.03 feet) and above
  • Sites with a reasonably unobstructed view of the sky

SPS GNSS Receivers


The ultra-rugged Trimble® SPS985 GNSS Smart Antenna offers unmatched reliability for construction site positioning. Ideal for use on small and large job sites, the SPS985 can serve as a GNSS rover system or as a Wi-Fi enabled base station for other GNSS operations including machine control.

Whether you need a reliable GNSS base station or a rugged rover, the Trimble® SPS855 GNSS Modular Receiver gives you the flexibility to perform all of your construction site measurements. As a permanent or semi-permanent base station, it provides GNSS corrections for site measurements and machine control. As a rover, it can move easily from a site supervisor truck to a pole mount for grade checking, site measurement and stakeout. Click here to contact us for more information.

To complement the range of modular receivers for heavy highway and marine construction, Trimble offers five models of GPS and GNSS antennas to suit the customer’s specific application and budget requirements. Click here to contact us for more information.

Trimble® Connected Site® solutions empower supervisors and foremen with the right information at the right time. From the job site, truck or office, they can be connected and equipped with accurate positioning, consistent digital design information and the ability to locate, measure and record information. They can also share information, track results instantly and manage multiple job sites with ease. Click here to contact us for more information.

With an ultra-rugged Trimble® SPS985 GNSS Smart Antenna on a rover pole and a Trimble TSC3 controller running SCS900 Site Controller Software, the grade checker has all of the tools necessary to stay on top of the hectic job. Trimble Site Positioning Systems and SCS900 field software were designed to simplify field workflows and data management for the grade checker, and they don’t require a surveying background to operate.
