Determination of an Estimation of Parameters of Motion of a Spacecraft on the Stage of Its Descent on the Basis of Integration of Inertial and Optoelectronic Navigation Systems

The problem of determining an estimation of current spacecraft motion parameters on the stage of its descent is solved on the basis of readings of an optoelectronic navigation system and additional information from the self-contained inertial navigation system at the most general assumptions on the nature of motion of the object and the statistical properties of the noise of the measuring devices.
