Tips
IMU, AHRS, or INS?
The Inertial Measurement Unit (IMU) outputs gyroscopes, accelerometers, and magnetometers raw data. The Attitude and Heading Reference System (AHRS) embeds an Extended Kalman Filter (EKF) to deliver orientation data, and the Inertial Navigation System (INS) additionally embeds a GNSS receiver for a filtered position in real-time.
Magnetic, Single or Dual Antenna GNSS Heading?
A single antenna is good enough for accurate heading in high dynamics UAV applications, while a 2 antenna GNSS receiver will provide a faster initialization as well as a more precise heading. When the UAV has low dynamics, single antenna is not recommended.
Which model for High Dynamics UAV?
For high dynamics UAV (catapulted for example), we recommend to use the heading based on magnetometers or on “GPS + acceleration” mode. When choosing the accelerometers option, note that the 16 g accelerometer is the best option.
