Product Description
DEPENDABLE WHEN EVERY POINT COUNTS
Designed for surveyors looking for easy-to-use GNSS technology, the Trimble? R4 GNSS System performs under even the most rigorous conditions. GNSS support upgrade options, integrated Trimble R-Track™ satellite tracking technology, and a straightforward system design result in a system that is flexible, reliable, and rugged.
A COMPLETE GNSS SYSTEM
Lightweight, convenient and cable-free, the Trimble R4 GNSS system with Trimble Access™ field software provides the ease of use of an integrated receiver and everything you need to perform a basic survey campaign.
ADVAN CED TRIMBLE R-TRACK TECHNOLOGY
The Trimble R4, powered with a Trimble Maxwell™ 6 chip with 220 channels, delivers the accuracy and reliability required for precision surveying with superior tracking and RTK performance. With GPS L2C and the Japanese QZSS support included, you can track more satellites and measure more successfully in challenging environments. L2C provides more than just additional signals - the advanced signal structure provides better strength for more reliable satellite tracking.
Trimble R-Track satellite tracking technology delivers reliable, precise positioning performance. 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 CMRx communications protocol provides correction compression for optimized bandwidth and full utilization all of the satellites in view, giving you reliable positioning performance.
CHOOSE THE LEVEL OF GNSS SUPPORT YOU REQUIRE TODAY
Choose the level of GNSS support you require today with the flexible upgrade options available on the Trimble R4. Founded on proven GNSS technology, the Trimble R4 comes standard with GPS L1, L2, L2C and QZSS. Beyond this standard GNSS support, the Trimble R4 offers upgrades to GLONASS, Galileo, and BeiDou (COMPASS)-just choose what you need.
FUNCTIONS AS A VRS ROVER, RT K ROVER, OR FIELD BASE STATION
Use as a lightweight rover for static surveying or RTK. The Trimble R4 is also completely compatible with Trimble VRS™ solutions, creating a VRS rover for use inside real-time networks. With a built-in 450 MHz receive-only radio or a fully integrated GSM/GPRS radio, this system can be adapted to meet a variety of needs. As a base station, the Trimble R4 with the integrated UHF transmit option is rugged, weather-resistant and compatible with a range of radio solutions.
A DEDICATE D, RELIABLE GNSS FIELD SOLUTION
Pair the Trimble R4 with Trimble Access and the Trimble Slate Controller1 for a dedicated GNSS solution that is effective for both real time and post processed GNSS surveys.
Powerful, connected, and compact, the Trimble Slate Controller combines the convenience and ease-ofuse of a smartphone with the durability for which Trimble is known. Its slim, ergonomic design is easy to grasp and its screen provides superior sunlight readability enabling all-day use by hard-working survey professionals.
Trimble Access field software provides specialized and customized workflows to make surveying tasks quicker and easier while enabling teams to communicate vital information between field and office in real-time.
Survey companies can also implement their unique workflows by taking advantage of the customization capabilities available in the Trimble Access Software Development Kit (SDK).
Need to get data back to the office immediately? Benefit from real-time data sharing via Trimble Access Services, now available with any valid Trimble Access maintenance agreement.
Back in the office, users can seamlessly process data with Trimble Business Center office software.
The Trimble R4 GNSS system - ready and reliable for your everyday surveying needs.
