GYROCOMPASS SYSTEM OF ORIENTATION OF ARTIFICIAL EARTH SATELLITE Russian patent published in 2013 - IPC G01C19/00 

FIELD: measurement equipment.

SUBSTANCE: gyrocompass system of orientation of artificial earth satellite includes a local vertical reference for a roll channel, five adder units, three amplifying-and-converting devices, angular velocity sensors unit, three integrators, three setting devices of programme angular velocity, a unit for shaping of corrections for heading and roll and a programme timing setting device of modes. With that, the unit for shaping of corrections is made in the form of in-series connected normally open contacts of the first switching device, a noise signal filter, for example of a non-periodic link, a digital arithmetic device, a scaling device and normally open contacts of the second switching device.

EFFECT: elimination of the influence of constant error of local vertical reference for roll and other errors, the action of which is equivalent to error of local vertical reference, on errors of the system of orientation for roll and heading without any deterioration of dynamics of correction circuits of the system.
