The A5700 high-precision MEMS heading and attitude reference system (AHRS) is a highly reliable and cost-effective six-axis MEMS inertial system for heading and attitude measurement, widely applicable in navigation, control, and measurement applications such as satellites, vehicles, ships, and drones. The A5700 series integration a high-performance MEMS gyroscope and MEMS accelerometer within a single integrated structure, with comprehensive compensation for temperature-dependent parameter zero points, scale factors, non-orthogonal errors, and acceleration-related terms, ensuring sustained high measurement accuracy. The system outputs attitude information through navigation calculations based on the angular motion of the three-axis MEMS gyroscope sensor and the linear acceleration measured by the three-axis MEMS accelerometer sensor.

Application Scenarios
A5500 series is an IMU/VRU/AHRS sensor composed of high-performance MEMS-IMU, magnetometer, and enhanced single axis gyroscope. It is equipped with self-developed adaptive extended Kalman filter, IMU noise dynamic analysis algorithm, and carrier motion state analysis algorithm, which can meet the accuracy of attitude angle under high dynamic conditions and reduce heading angle drift. Every sensor undergoes fine compensation including temperature, zero bias, scaling factor, and cross axis before leaving the factory.
