GNSS Systems

Backed by a legacy of GNSS technology leadership and surveying expertise, Trimble provides surveyors with reliable, innovative GNSS survey solutions that meet their distinct requirements.

For more than 30 years, Trimble has set the standard for positioning technologies, and intends to continue that tradition well into the future.

Integrated GNSS Systems

Modular GNSS Systems

Software Based Receivers



As the UK and Ireland’s largest Trimble distributor, KOREC supplies a wide range of surveying, mapping and geospatial solutions to multiple industries. In particular Trimble is renowned for its innovative GNSS systems establishing its reputation over 30 years.

These systems are innovative and ground breaking with the latest releases including the Trimble R12, which introduced geospatial professionals to Trimble ProPoint™ GNSS Technology which greatly improves performance in challenging GNSS conditions. This was followed by the Trimble R12i which offers Trimble TIP Tilt Compensation Technology – Inertial Measurement Unit (IMU) based tilt compensation for accurate setting out and measuring points without precisely levelling the pole.

Other Trimble GNSS technologies include Trimble CenterPoint RTX® Correction Service providing RTK level precision worldwide without the need for a base station or VRS network and Trimble xFill® Technology designed to keep you working in radio and cellular black spots with continuous RTK coverage.

Additionally, Trimble GNSS receivers include the Trimble R10, designed to collect more accurate data faster and easier and the Trimble R8s, a configurable receiver that is scalable for future needs, the Trimble R2 which is also suitable for GIS mapping data capture applications and the pocket sized Trimble R1 designed for mobility.

As well as bringing excellent accuracy and reliable performance, Trimble GNSS can be used with a choice of data collectors. These range from the high-end powerful Windows  Trimble TSC7 which combines a large screen with rugged performance running Trimble Access field software, to the Android Trimble TDC600 handheld, a sleek, all-in-one rugged smartphone with a built-in professional GNSS receiver that runs the newly launched Trimble Access 2020 software.

The GNSS systems are also compatible with Trimble VRS Now, Trimble’s RTK correction service.
