Distinguishable features
Each AHRS500GA is shipped with an interface cable (used during installation alignment), MEMSIC’s 500 Series User’s Manual and GYRO-VIEW 2.0 configuration and display software. The AHRS500GA is designed for standalone operation, but may also be used with MEMSIC’s CRM500 remote magnetometer for installations requiring a wing or tail mount magnetometer.
