Colibrys - MEMS Motion Sensors for Aerospace

The main accelerometer parameters essential to optimum AHRS performance are bias stability, scale factor stability, axis misalignment and its stability and, second order linearity effects or VRE (vibration rectification error). Colibrys offers MS8010.D and MS9010.D as ideal products for AHRS and is continuously working on new improved versions, providing further capabilities.

An attitude heading reference system (AHRS) is a particular inertial navigation system, combined of three-axis sensors (self-contained accelerometers and gyros) that provide heading, attitude and yaw information for aircraft or any subject moving in free space or under water. In general, the role of accelerometers in an AHRS application is to provide with initial attitude reference (levelling) and attitude corrections during the flight by correcting the gyro drift.

Low G inertial sensors, due to their high resolution, high temperature stability and low power consumption, are extremely good products for tilt sensing.
