Trimble R8 Model 2 GPS GLONASS L1 L2 L2CS L5 450-470MHz Base & Rover RTK

Trimble R8 Model 2 Receiver

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 Maxwell™ 6 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 1,2 . 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 or base operation . As a base station, the internal NTRIP caster provides you with customized access 3 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 post-processing data through Web UI and save additional trips out to the field .

Enabling The Connected 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
