METHOD AND DEVICE FOR CELESTIAL-INERTIAL NAVIGATION Russian patent published in 2012 - IPC G01C21/00 

FIELD: navigation equipment.

SUBSTANCE: celestial-inertial navigation system is created by rigidly fixing inertial and celestial navigation systems in their own separate casings together in the Y2 plane, an optical window is created in the mutual wall between them, and optical binding signals for instrument coordinate systems are formed, these signals are used to calculate navigation errors and true flight characteristic values. The device comprises three gyroscopes and three accelerometers installed on the same common base inside the first casing, and a celestial navigator inside the second casing, furthermore, both casings are also fitted with optical correcting units working on artificial light sources. The tolerance signal image of navigation errors of tilting, pitching and course is formed on the coordinate-connected array, these signals are taken into consideration when true flight characteristic values are calculated.

EFFECT: error reduction for measuring true course, angular location and spatial position of the object.
