Application Note: AHRS in UAVs
An unmanned system requires precise navigation and guidance information in a reduced size and weight for its autonomous flight. Controlling an aerial vehicle is a challenging and risky task, therefore, it is important for the sensor suite to be reliable and field-proven with the capability of delivering data quickly and accurately about the vehicle’s attitude and direction.
The evolution of MEMS technology has allowed us to be able to count on high-quality attitude and heading measurements in a lightweight device with a reduced size, but at the same time, with great reliability.
One of the cornerstones of UAV Navigation is its in-house developed AHRS devices with advanced algorithms that fuse the data provided by multiple sensors (GNSS, airspeed, magnetometers, gyroscopes, accelerometers, etc) and has proven its cutting-edge performance in dead reckoning and challenging conditions even against FOG units (used in manned aviation, much heavier, and bigger).
This way, clients are able to take advantage of all the potential features and the experience invested to develop the POLAR-AHRS family and use it in their UAV platforms. They will be able to use the data stream from our tested and optimized attitude and heading reference system to develop their own Flight Control Computer (FCC).
Featured Products: POLAR-300 & POLAR-500
The POLAR family is a high-end, Microelectromechanical Systems-based (MEMS), Air Data Attitude and Heading Reference System (ADAHRS), and Inertial Navigation System (INS). It has been designed for system integration in avionics and other attitude sensing applications.
