Reconstruction of spacecraft Progress attitude motion in single axis solar orientation mode by measurements of current from solar arrays
Abstract:
We reconstructed the uncontrolled attitude motion of the cargo spacecraft Progress M-24M, M-25M, MC-05 и MC-06 in the single-axis solar orientation mode (so-called solar rotation). At the beginning of the oriented motion, the spacecraft rotated around the normal to solar batteries with angular rate 2.2 deg./s and the normal was directed to the Sun. The oriented motion lasted for a few orbit revolutions. The reconstruction was made using measurements of the electric current from spacecraft solar arrays. The measurement data, collected in a time interval about a few tens of minutes, were processed simultaneously by statistical methods and integration of the spacecraft attitude motion equations. As a result, the spacecraft attitude motion was reconstructed relative to the direction Earth – Sun. The investigation of the current specter showed the possibility of this way of motion reconstruction using current measurements, which were seemed to be not informative for this purpose.
