Trimble R8 Model 2 GNSS Receiver
The Trimble R8 Model 2 is an integrated GNSS system that combines a multi frequency receiver antenna and data link radio in one compact unit with no cables to a separate antenna or controller. It was built for surveyors facing demanding RTK applications and it works as a rover a base or a network (VRS) rover. It is part of Trimble well known R8 family which set a benchmark for integrated survey-grade GNSS.
Key Features
- Integrated all-in-one design: receiver, antenna, radio, and battery in a single sealed unit so the pole setup stays light and uncluttered
- Multi-frequency, multi-constellation tracking: supports GPS L1/L2 the modernized GPS L2C and L5 signals and GLONASS L1/L2, with a design aimed at keeping the unit useful as GNSS evolves
- R-Track technology: an enhanced real time kinematic (RTK) engine for tracking in demanding conditions
- Precise, stable antenna: a patented antenna design with sub millimeter phase center stability and very low noise carrier phase measurements
- Built-in radio options: an integrated fully sealed 450 MHz UHF radio with receive only versions (for example, 430-450 MHz) and 450-470 MHz versions available programmable to your frequencies
- SBAS support: WAAS and EGNOS capability for real time differential positioning without a base station
- Flexible operation: use it as a rover with a base as a base station or as a network rover through VRS
- Wireless connection to the controller: Bluetooth links the receiver to a field controller such as a Trimble TSC3 with Trimble Access for cable free work on the pole
- Rugged and weatherproof: a sealed housing with the receiver operating normally down to -40 °C (internal batteries and Bluetooth are rated to -20 °C)
- Removable batteries: hot swappable power for a long day in the field
- Firmware updatable: keep the receiver current with Trimble firmware releases
Typical Applications
- Topographic, boundary, and cadastral surveys
- Construction layout and stakeout
- Control surveys and reference station work
- Network RTK and VRS surveying
- Engineering and infrastructure projects
Why Choose It
The R8 Model 2 delivers proven survey grade GNSS performance in a compact cable free package. Its radio options, Bluetooth link, and base rover or network operation make it a versatile choice for crews who want one dependable receiver for different jobs.
