MAH-A501
MEMS AHRS
Product Overview
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.
Core Advantages
Full-temperature calibration compensation from -45℃ to +80℃, compact size, light weight and low power consumption. Integrated adaptive attitude algorithm, supports 1kHz high-speed sampling and features robust performance under harsh mechanical environments.
