Determination of the passive attitude motion of the "Mir" orbital station, based on magnetic field strength measurement data.
Abstract
The technique is described for determining the passive attitude motion of the "Mir" orbital station by means of processing onboard measurements of the Earth's magnetic field strength vector. The measurement data, collected on a time interval of about two hours, are processed jointly by means of the least squares method using the integration of the station attitude motion equations. The estimations of initial conditions of the attitude motion and of aerodynamic parameters are obtained as a result of such processing. Possibilities are foreseen for estimating the station's tensor of inertia and for eliminating a constant error component from measurement data. Examples are given to determine the real passive motion of the station.
