The ELT0251 from GNSS.store is an ultra-light DroneCAN compass designed for Unmanned Aerial Vehicles (UAVs), robotics, and autonomous platforms.
Compass performance plays an important role in autonomous flight. Built-in compass modules are often positioned close to motors, Electronic Speed Controllers (ESCs), batteries, and high-current wiring, where magnetic interference is strongest. This can result in noisy magnetic data, unstable yaw estimation, and less reliable navigation.
The ELT0251 can be mounted away from power electronics to help reduce magnetic interference and improve navigation stability.
RM3100 Magneto-Inductive Sensor
Based on PNI’s proprietary magneto-inductive technology, the RM3100 delivers professional-grade heading accuracy, ultra-low drift, exceptional resolution, and repeatability. With a resolution of 10 nT and extremely low magnetic hysteresis, the sensor is suited to applications that demand precise heading accuracy.
DroneCAN Integration
The ELT0251 features the DroneCAN output protocol, providing reliable long-distance connectivity and simplified integration without using serial ports. Despite its protective housing, the module remains highly compact and is fully compatible with Pixhawk, PX4, and ArduPilot, making it suitable for precise and stable navigation.
