Benchmark Surveys has a range of Trimble and Topcon GPS systems. We use these to increase accuracy on all our surveys.

The GPS can be used for setting out (engineering works), topographic surveys and monitoring surveys.


Our Trimble GPS system is the R10 GNSS System –
Trimble xFill™ provides less downtime in the field, with continuous RTK coverage during connection outages from an RTK base station or VRS network.

Trimble CenterPoint™ RTX™ delivers GNSS corrections via satellite or internet connection anywhere in the world for unprecedented speed and accuracy for a PPP solution.
Cutting edge Trimble HD-GNSS processing engine enables surveyors to measure points more quickly.

Our Topcon GRS-1 System –
Topcon’s GRS-1 (Geodetic Rover System) is the fully integrated dual constellation network enabled RTK rover system. It is an all-in-one handheld GNSS receiver and field controller featuring high-speed processor, increased memory, built-in camera and digital compass.
