BD940-INS

Unmatched Precision with GNSS + Inertial Integration

The Trimble BD940-INS combines advanced GNSS technology with precision inertial sensors in a compact, rugged module. Designed for applications demanding continuous centimeter-level accuracy, it delivers robust positioning even in challenging environments such as urban canyons or GNSS-denied areas.

By integrating inertial sensors directly on the board, the BD940-INS ensures uninterrupted, high-accuracy navigation. Its fully shielded GNSS components protect signal integrity from electromagnetic interference (EMI) on the host platform.

Multi-Constellation, Triple-Frequency Support

The BD940-INS supports:

• Triple-frequency GNSS for GPS and GLONASS
• Dual-frequency for BeiDou and Galileo

This broad compatibility ensures fast and reliable RTK initialization, enabling 1–2 cm positioning accuracy. As satellite constellations expand, the BD940-INS is ready to leverage additional signals for even greater performance.

For applications not requiring RTK-level accuracy, the integrated GNSS + Inertial engine provides high-precision GNSS and DGNSS positioning—even in the most demanding environments.

High-Performance Inertial Sensors

The BD940-INS is more than a GNSS receiver—it's a complete navigation solution. Key features include:

• High-rate position and orientation updates
• Continuous navigation in GNSS-denied environments
• Lever arm compensation from antenna to point of interest
• Robust Moving Baseline RTK for dynamic platforms
• Single-antenna heading unaffected by magnetic interference

Powered by Trimble ProPoint™ Engine

Now featuring the Trimble ProPoint™ Engine, the BD940-INS delivers superior accuracy, availability, and integrity in degraded GNSS conditions—ideal for mission-critical applications.

Flexible Integration & Connectivity

Engineered for seamless integration, the BD940-INS offers:

• Ethernet for high-speed data transfer and web-based configuration
• USB and RS-232 interfaces
• Intuitive 3D web interface for lever arm input and vehicle model selection

All features are password-upgradable, allowing you to scale functionality as your needs evolve. Optional support for OmniSTAR and Trimble RTX services enables centimeter-level accuracy without a base station.
