Abstract:

The press reports of recent years mention the attempts to use the earths gravity field for the orientation of space ships. According to the published data, the attainable orientation accuracy is of an order of 1-2 min. As data units of different kinds, the control systems use the inertia systems which measure certain linear functions of second derivations of the potential. The accuracy of measurements amounts to 10 to the -4 of the measured value. In the present article it is shown that the measurement of the second derivations of potential can be used not only for the purposes of orientation, but also for the determination of a trajectory of the body. The demonstration is carried out with the aid of two idealized models. Author
