MEMS AHRS
Product Overview of MAH-A501 MEMS AHRS
MAH-A501 is a high-dynamic, high-reliability and cost-effective 6-axis MEMS inertial attitude heading reference system. The module implements full-temperature compensation for bias, scale factor, non-orthogonality error and acceleration-related terms to maintain high measurement accuracy over long durations. Adopting integral vibration damping and hermetic sealing design, it is widely applied in navigation, control and measurement domains including satellites, vehicles, ships and UAVs.
Built for unmanned platforms, this compact unit delivers stable attitude output even under complicated dynamic motion. Its built-in compensation algorithm eliminates temperature drift errors across the full working range, removing the requirement for frequent on-site recalibration for most integration projects. Engineers can directly feed its attitude, heading and angular rate data into flight controllers, vehicle navigation units and stabilization servo systems.
Core Advantages of this MEMS AHRS
