Systork has unveiled the Brant RM3100, a robust external magnetometer designed to deliver clean, stable, and precise magnetic field measurements even in the noisiest environments.

Specifically engineered to overcome electromagnetic interference for sensors onboard unmanned aerial vehicles (UAVs), Brant is equipped with the industry-proven RM3100 magnetometer, known for its exceptional stability and accuracy. Featuring a compact 35 mm x 35 mm casing and practical mounting ears, Brant is built for quick installation.

With two integrated DroneCAN connectors, this robust plug-and-play solution enables direct communication with the autopilot and removes the need for additional adapters, ensuring smooth integration.

Inertial Measurement Unit (IMU) Applications
While Brant was designed with UAVs in mind, it also excels in IMU applications. Its ability to deliver clean magnetic data makes it an excellent companion for IMU setups that require uncompromising accuracy in motion tracking and orientation.

Rather than compromising between size, robustness, and performance, Brant delivers all three. It integrates easily with PX4 and ArduPilot systems, supports open-source development, and is designed and manufactured in France by Systork’s in-house engineering team.

External vs. Internal Magnetometers
Internal magnetometers in flight controllers are often disrupted by the aircraft’s own electrical systems, particularly the motors, which generate significant electromagnetic interference. This can lead to inaccurate orientation data and flight instability.

The Brant RM3100 isolates the magnetometer from these disturbances, ensuring consistent, high-fidelity heading information, a key advantage for precise navigation and flight stability.
