The Trimble R8 Model 3 GNSS Receiver sets the new standard for full-featured GNSS (Global Navigation Satellite System) receiver technology. This integrated system delivers unmatched power, accuracy and performance in a rugged, compact unit.

Loaded with 220 channels receiver with base and rover functionality,  able to track GPS L1 / L2, L2C, L5 and GLONASS signals, also aability to track the Galileo constellation (optional upgrade). It featured ”R-Track Signal Prediction” which greatly improved the receiver’s performance around canopy and other sky obstructions (for short bursts of time).  Where the Trimble R8 Model 2 would maintain a fixed solution at the outer extents of a tree’s foliage, the Trimble R8 Model 3 enabled you to take shots under light to medium canopy. CMRx was a new protocol that was necessary for the receiver to compress and transmit the data that was now being tracked on those 220 channels. 57 MB of internal memory was upgraded for storing GNSS observations (post processing). Finally – the internal UHF radio transmit option was now a standard feature.

Advanced Trimble R-Track Technology

The Trimble R8 GNSS delivers the latest advancements in R-Track technology, designed to deliver reliable, precise positioning performance. In challenging areas for GNSS surveying, such as tree cover or limited sky view, Trimble R-Track provides unmatched tracking performance of GNSS satellite signals.

Trimble R-Track with Signal Prediction compensates for intermittent or marginal RTK correction signals, enabling extended precision operation after an RTK signal is interrupted.

The new CMRx communications protocol provides unprecedented correction compression for optimized bandwidth and full utilization all of the satellites in view, giving you the most reliable positioning performance.

Featuring the Trimble Maxwell6 chip, the Trimble R8 GNSS advances the industry with more memory and more GNSS channels. Trimble delivers business confidence with a 
sound GNSS investment for today and into the future.

Broad GNSS support

The Trimble R8 GNSS supports a wide range of satellite signals, including GPS L2C and L5 and GLONASS L1/L2 signals. In addition, Trimble is committed to the next generation of modernized GNSS configurations by providing Galileo-compatible products available for customers well in advance of Galileo system availability. In support of this plan, the new Trimble R8 GNSS is capable of tracking the experimental GIOVE-A and GIOVE-B test satellites for signal evaluation and test purposes .

Flexible System Design

The Trimble R8 GNSS receiver combines the most comprehensive feature set into an integrated and flexible system for demanding surveying applications. The Trimble R8 GNSS  includes a built-in transmit/receive UHF radio enabling ultimate flexibility for rover orbase operation. As a base station, the internal NTRIP caster provides you with customized access to base station corrections via the internet.

Trimble’s exclusive, Web UI eliminates travel requirements for routine monitoring of  base station receivers. Now you can assess the health and status of base receivers and  perform remote configurations from the office . Likewise, you can download postprocessing data through Web UI and save additional trips out to the field

Enabling the connnected site

Pair the speed and accuracy of the Trimble R8 GNSS receiver with flexibility and  collaboration tools of Trimble Access software. Trimble Access brings field and office teams closer by enabling data sharing and collaboration in a secure, web-based environment. With optional streamlined workflows, Trimble Access further empowers  surveyors and survey teams for success. Now it is easier than ever to realize the potential of the Trimble Connected Site. Connecting the right tools, techniques, services and relationships enables surveying businesses to achieve more every day
