Trimble BD935-INS

The Trimble BD935-INS module features a high accuracy, triple frequency GNSS receiver for precise position and an integrated MEMS inertial sensor package for 3-D orientation to serve applications requiring position and attitude. The GNSS + Inertial combination delivers more stability and robustness than GNSS alone.

Key Features:

Onboard high accuracy inertial sensor package integrated with GNSS for precise position and orientation
336 Channels for multi-constellation GNSS support
EMI shielded module
Compact design for mobile applications
Flexible RS232, USB and ethernet interfacing
Centimeter level position accuracy
Proven Trimble Maxwell technology

GNSS and inertial tight integration

Taking advantage of Trimble’s expertize in both GNSS and Inertial technology the Trimble® BD935-INS module has been designed for applications requiring continuous centimeter accuracy in a compact package. By integrating inertial sensors on the same module, robust high accuracy positions are produced in all environments. A single intuitive web interface and interface protocol allows a variety of dynamic models to be supported. The GNSS components are fully shielded. This design ensures the high quality signals are protected from the sources of EMI on the host platform.

Multiconstellation GNSS

The Trimble BD935-INS supports both triple frequency for the GPS and GLONASS constellations plus dual frequency from BeiDou and Galileo. As the number of satellites in the constellations grows the BD935-INS 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 BD935-INS integrated GNSS-Inertial engine delivers high accuracy GNSS, DGNSS positions in the most challenging environments such as urban canyons. Diff erent confi gurations of the module are available. These include everything from a DGPS 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 Receiver. Autonomous Integrity Monitoring (RAIM) for safety-critical applications.

High performance integrated inertial sensors

The Trimble BD935-INS integrates the latest in precision inertial sensors in a compact package. With the BD935-INS you are buying a robust navigation solution, not just a GNSS receiver. Key features include:

High update rate position and orientation solutions
Continuous positioning in GNSS denied environments
Lever arm calculation from antenna to navigation point of interest
Robust Moving Baseline RTK for precision landing on moving platforms
Single antenna heading not infl uenced by magnetic fi eld variations

Flexible Interfacing

The Trimble BD935-INS was designed for easy integration and rugged dependability. Customers benefi t from the Ethernet connectivity available on the board, allowing high speed data transfer and confi guration 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.
