Introduction

The Trimble® BD930 supports both triple frequency from the GPS and GLONASS constellations plus dual frequency from BeiDou and Galileo. As the number of satellites in the constellations grow the BD930 is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for 1–2 centimeter positioning. For applications that do not require centimeter accuracy the BD930 contains an advanced kalman filter PVT engine that delivers high accuracy GNSS, DGNSS positions in the most challenging environments such as urban canyons. Different configurations of the module are available. These include everything from an autonomous GPS L1 unit all the way to a four constellation triple frequency RTK unit. Choose the receiver that suits your application and price point. All features are password-upgradeable, allowing functionality to be upgraded as your requirements change.

The receiver also supports Fault Detection and Exclusion (FDE) and ReceiverAutonomous Integrity Monitoring (RAIM) for safety-critical applications.

COMPACT FULL METAL JACKET DESIGN

The Trimble® BD930 GNSS receiver module has been designed for applications requiring centimeter accuracy in a very small package. Mobile platforms can now embed proven Trimble RTK technology using a shielded module with a 51 mmx 41 mm x 7 mm form factor. The Trimble BD930 is a complete drop-in, solderdown module manufactured and tested to Trimble’s highest quality standards. This design ensures the high quality GNSS signals are protected from the sources of EMI on the host platform. It also significantly reduces radiated emissions which speeds compliance certification and time to market. 

DEMONSTRATED PERFORMANCE

Industry professionals trust Trimble embedded positioning technologies as the  core of their precision applications. With the latest Trimble-precise Maxwell™ 6technology, the BD930 provides assurance of long-term future-proofing and trouble free operation. Moving the industry forward, the Trimble BD930 redefines highperformance positioning:

  • On-board multipath mitigation
  • Proven low-elevation tracking technology

FLEXIBLE INTERFACING

The Trimble BD930 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 and RS-232 are also supported. Just like other Trimble embedded technologies, easy to use software commands simplify integration and reduce development times.
