A system and method for monitoring and verification of digital gyroscopic sensors determines a primary angular velocity vector via a primary digital gyroscopic sensor triad and two or more backup angular velocity vectors via backup analog gyroscopic sensor triads. Based on additional aiding parameters, the aircraft attitude and heading reference system (AHRS) determines a primary attitude solution based on the primary angular velocity vector and one or more backup attitude solutions based on the backup angular velocity vectors. If no other faults are present with respect to the primary and backup gyroscopic sensor triads (e.g., the primary and backup triads are otherwise consistent in their measurements), and the primary attitude solution sufficiently deviates from the backup attitude solutions, the AHRS detects a solution fault in the primary gyroscopic sensor triad.
