Introduction

The Trimble® BD970 GNSS system is a compact multi-constellation receiver designed to deliver centimeter accuracy to a variety of applications. With the Trimble BD970, OEM's and integrators can be assured their investment is sound today and into the future. The Trimble BD970 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 addition, Trimble is committed to the next generation of modernized GNSS configurations by providing Galileo and Compass compatible products available for customers well in advance of these systems becoming available. In support of this plan, the Trimble BD970 is capable of tracking both Galileo and Compass signals for evaluation and test purposes.

Demonstrated Performance

Industry professionals trust Trimble embedded positioning technologies as the core of their precision applications. With the latest Trimble-precise Maxwell™ 6 technology, the BD970 provides assurance of long-term future-proofing and trouble free operation. Moving the industry forward, the Trimble BD970 redefines high performance positioning:

  • On-board multipath mitigation
  • Proven low-elevation tracking technology
  • Dramatically improved RTK initialization times

Flexible Interfacing

The Trimble BD970 was designed for easy integration and rugged dependability. Customers benefit from the Ethernet connectivity available on the board, allowing high speed data transfer and configuration via standard web browsers. USB, RS232 and CAN are also supported. Just like other Trimble embedded technologies, easy to use software commands simplify integration and reduce development times. All software features are password-upgradeable, allowing functionality to be upgraded as your requirements change.

Compact Design

The compact form factor is suitable for applications where lightweight is a necessity. The BD970 is rigorously tested to perform in the harsh environments your products are built for, with the reliability you expect from Trimble.
