ASTRONOMICAL NAVIGATION SYSTEM Russian patent published in 2017 - IPC G01C21/02 

Abstract RU 2607197 C2

FIELD: instrument making.

SUBSTANCE: invention relates to instrument making and can be used in high-precision astroinertial navigation systems of aircrafts (AC). For this purpose, astroinertial AC system is additionally introduced with gravimeters, altimeters unit for measuring vertical acceleration of aircraft, gravitational acceleration processing unit and adders, the gravimeters are mounted on a separate platform, made with possibility of synchronous movement with aircraft and parallel to horizontal plane, the outputs of gravity meters and altimeter unit for measuring of vertical acceleration of aircraft are connected to computer inputs of gravitational acceleration meter which outputs are connected through adders to navigation computer of gimballess inertial navigation system, and outputs of accelerometers are connected to second inputs of adders.

EFFECT: technical result consists in increase of accuracy of output parameters by taking into account during measurements in real time of change of gravitational components of gravity acceleration.
