FIELD: physics; navigation.
SUBSTANCE: invention relates to instrument making and can be used in strapdown inertial reference systems (SIRS), particularly strapdown attitude reference systems (SARS) integrated into the air data system (ADS). To achieve the result, the strapdown attitude reference system has three computer navigation platforms, each of which has its own control law. Each platform damps inertial errors in accordance with its own law. The master-filter platform which receives output signals carries out their optimal (in the mean-square sense) processing.
EFFECT: increased accuracy.
