METHOD OF INSPECTING ALIGNMENT OF GYROSTABILISED PLATFORM OF INERTIAL SYSTEM Russian patent published in 2015 - IPC G01C25/00 

FIELD: physics.

SUBSTANCE: method comprises initial alignment of a gyrostabilised platform; determining orientation of the coordinate system associated with the gyrostabilised platform relative to the local horizontal coordinate system associated with the Earth; calculating the result of independent determination of the azimuth of the gyrostabilised platform α_η; determining the astronomical azimuth A_CE of the control element of the gyrostabilised platform, the position of the normal to which coincides with the zero reading of an angle φ sensor; at the end of the initial alignment, measuring the angle φ of the gyrostabilised platform around the axis of a gimbal suspension and determining the gyrocompassing error ΔA: ΔA=α_η-A_CE-φ; alignment of the gyrostabilised platform is considered to have passed the inspection of the gyrocompassing error does not exceed an acceptable value.

EFFECT: high reliability of inspecting initial alignment of a gyrostabilised platform.
