MAH-A502
MEMS AHRS
Product Overview
MAH-A502 is a high-reliability, cost-effective 6-axis MEMS inertial attitude heading reference system. Inside the module, full-temperature compensation is implemented 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 used in navigation, control and measurement fields such as 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 is robust against harsh mechanical environments.
