The Posteriori Precision Evaluation of the Definition of User's State Vector on Measurements of Pseudorange and Dopler Frequency for GPS Satellite Navigation System.

Abstract: Using the perfomances of satellite navigation systems for control purposes in complicated engineering systems require the high reliability to the hardware-software complex of user's navigation receivers. The purpose of this work is to study of possibility of using the perfomances of satellite navigation system in spacecraft's control system. The algorithm is offered for improvement of user's state vector determination and registration time of navigation signal on measurements of pseudorange and doppler frequency. The statistical evaluations was obtained determined for parameters using each seconds raw measurements accumulated on one-month interval.Note: Research direction:Theoretical and applied problems of mechanic
