Uncontrolled attitude motion of the prototype of the small spacecraft Aist
Abstract:
We present the results of reconstruction of the uncontrolled attitude motion of the prototype of the small spacecraft Aist during its flight at the beginning of 2014. The reconstruction was realized by processing onboard measurements of the Earth magnetic field. The measurement data were accumulated in time segments, which had length about 100 min. The measurement data on each such segment were processed sim-ultaneously by means of the least squares method and integration of the spacecraft attitude motion equations. The estimates of the mathematical model parameters and initial conditions of the attitude motion were obtained as a result of such processing. The results of processing some segments above made clear the attitude motion of the spacecraft.
