TBS DroneCAN GPS Module UBX-M9140: Professional Grade CAN Bus Navigation

The TBS DroneCAN GPS Module UBX-M9140 is the essential component for building reliable, high-performance, and large-scale unmanned aerial vehicles (UAVs). Leveraging the noise-resistant CAN Bus protocol (DroneCAN), this module ensures flawless digital communication with your flight controller, eliminating the issues often associated with long analog wiring runs.

Advanced Navigation and Digital Reliability:

• U-blox M9 Chipset: Powered by the advanced u-blox UBX-M9140 chipset, this module supports up to four concurrent global navigation satellite systems (GPS, GLONASS, BDS, GALILEO), achieving high positional accuracy of 1.5m CEP.

• High Update Rate: Essential for accurate flight control, the module boasts a refresh rate up to 25Hz, providing faster, more responsive positional data for mapping, autonomy, and RTH (Return-to-Home) functions.

• Integrated Magnetometer: Includes the reliable QMC5883 Compass for accurate heading reference, crucial for advanced flight modes and safe operation.

• DroneCAN/CAN Bus Integration: The DroneCAN standard offers robust, error-checked communication, making installation simpler (plug and play) and highly reliable for complex and industrial applications.

• Fast Acquisition: Provides excellent acquisition times, including a quick 2-second Hot Start and a rapid 24-second Cold Start.

• Dedicated MCU: Features an Arm Cortex-M3 MCU (72MHz) for managing CAN communication and data processing, ensuring minimal load on the main flight controller.

The TBS DroneCAN GPS module is the ideal solution for professional builders and advanced hobbyists seeking the highest standard in high precision GPS and communication reliability for their mission-critical aircraft.
