High-Precision IMU Dead Reckoning GNSS Modules for UAVs, Robotics & Automotive

Standard satellite navigation fails when line-of-sight is lost, but our IMU Dead Reckoning GNSS modules ensure continuous positioning by fusing automotive-grade IMU sensors with advanced GNSS data. For the complete, detailed promotional and technical text, please refer to the referenced web documents.

Key Advantages & Enterprise Modules

ADR vs. UDR: ADR (Automotive Dead Reckoning) uses external odometer feeds for heavy machinery, while UDR (Untethered Dead Reckoning) like the NEO-M9V series operates on internal 3D IMU sensors.
Hardware Selection: We stock top industry chipsets including u-blox (ZED-F9R & NEO-M9V) and Unicore, compatible with standard flight controllers and protocols.

FAQ: IMU Dead Reckoning GNSS Modules

What is the advantage of IMU Dead Reckoning over standard GNSS?

Standard GNSS requires a clear line of sight to satellites. When the signal is blocked (e.g., in a tunnel), position is lost. IMU Dead Reckoning uses internal sensors (accelerometers and gyroscopes) to calculate your position based on your last known point and movement, ensuring seamless navigation.

Are these modules suitable for high-speed UAVs or FPV drones?

Yes. The integration of an IMU allows for much faster update rates and better orientation data, which is critical for the stability and flight control of UAVs and FPV drones, especially during aggressive maneuvers. Modules like the u-blox ZED-F9R and M21 RTK with deeply coupled IMU are highly recommended for UAV flight control

Do I need a separate speed sensor for Dead Reckoning to work?

It depends on the module. We offer UDR (Untethered Dead Reckoning) modules that work using only the internal IMU, and ADR (Automotive Dead Reckoning) modules that can take an external odometer feed for even higher accuracy in vehicles.

How accurate is the positioning in "Urban Canyons"?

While accuracy depends on the specific environment, our IMU-fusion modules significantly reduce multi-path errors and "position jumps" common in cities with tall buildings, providing a much smoother and more reliable track compared to standard receivers.

Are these modules compatible with standard flight controllers?

Yes, using standard NMEA/UBX over UART, I2C, or SPI interfaces, they connect perfectly to Pixhawk, ArduPilot, and Raspberry Pi HATs.
