The Pseudorange of GPS Measured on the C/A Code. The Model of Error and Apriori Precision Evaluation of User’s State Vector.
The purpose of this work is study of possibility building spacecraft's control system using satellite navigation GPS/GLONASS system. The sources of pseudorange errors were investigated. The statistical model of pseudorange errors was obtained. The accuracy comparison of the pseudorange measurement with its actual values is carried out. The evaluation of apriori precision was obtained for user's state vector.
