Signal Processing in Astroinertial Attitude Determination System for the Space Robots

Yevgeny Somov, Sergey Butyrin, Sergey Somov, Tatyana Somova
We consider some principal problems on precise attitude determination of the free-flying robots and maneuvering land-survey mini-satellites operated on the orbit altitudes from 550 up to 1000 km. We present onboard discrete algorithms for nonlinear signal processing, calibration, alignment and verification of an astroinertial attitude determination system which is a part of the strapdown inertial navigation system.
