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.

FAQs

GNSS accuracy is dependent on the type of receiver and technology involved. For example, whilst a GPS Smartphone can offer an accuracy of around 4-5m in open skies, an advanced commercial GNSS system such as Trimble’s R12i can offer an accuracy of up to 3mm. GNSS accuracy can be affected by external conditions such as high buildings, heavy tree canopy or an insufficient number of satellites. The R12i features technology that makes it the most reliable choice for operating in inhospitable GNSS conditions.

If an accurate position is required, then there is an application for GNSS technology, consequently it is adopted by many people within many different industries and market sectors. For example, KOREC offers Mapping GNSS products that are used for the positioning of everything from lampposts and street furniture to gullies, footpaths, trees and fibre optic cables, anything where decimetre accuracy is more than sufficient which includes navigating back to previously recorded points. It has particularly high take-up for environmental, utilities and local government applications.
The KOREC range of survey GNSS with their mm accuracy are more suitable for infrastructure and civil engineering applications where accuracy is vital, for example the rail industry, construction, highways, forensics and collision site investigation and topographical surveys.

GNSS stands for Global Navigation Satellite System. This is an umbrella term that covers all global satellite positioning systems including GPS (Global Positioning System) a constellation of satellites developed by the United States Department of Defence originally for military use but now available for commercial and consumer use.
The main difference between the two is that GNSS systems provide increased accuracy and reliability because they can use satellites from other networks beyond the GPS system, for example GLONASS (Russian), EGNOS (European), Galileo (European) and Beidou (Chinese).
GNSS-compatible equipment can use navigational satellites from other networks beyond the GPS system, and more satellites means increased receiver accuracy and reliability. All GNSS receivers are compatible with GPS, but GPS receivers are not necessarily compatible with GNSS. The most advanced instrument in KOREC’s range is the Trimble R12i whilst the Trimble R1 is more basic, pocket sized receiver.

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.
