The SP-9 AHRS
High grade ring gyro based AHRS and built in SP-6 magnetometer for magnetic heading.
The SP-9 employs latest micro-machined ring gyroscope technology for performance that approaches FOG class ability in practical applications.
Adding ORION class high accuracy accelerometers results in an IMU grade AHRS.
