INERTIAL STRAPDOWN SYSTEM Russian patent published in 2015 - IPC G01C21/10 

FIELD: physics, navigation.

SUBSTANCE: invention relates to ACS and can be used in ACS operated under extreme conditions and ionising radiation fields. Claimed strapdown system comprises the unit composed of three accelerometers located in axes aligned with faces of arbitrary cube outgoing from one vertex. Note here that diagonal of said cube outgoing from the same vertex is aligned with the main axis of controlled structure (engine thrust axis). Outputs of all accelerometers are connected to inputs of special-purpose computer. Results of data processing for all accelerometers are transmitted therefrom to onboard computer for processing of data of angular velocity transducer unit special-purpose computer. Said special-purpose computer comprises four angular velocity transducers with sensitivity axes of three of them being located in axes aligned with cure faces outgoing from one vertex while axis of the fourth one is aligned with cube diagonal. Note here that said system comprises electric power supply subsystem configured to redundant version with built-in unit for control over operation of all its units and control over redundancy.

EFFECT: enhanced performances.
