Abstract :
A new approach to improve the accuracy and stability of space navigation/time determination is proposed and investigated. The covariance between the components´ estimation error covariance matrices (user coordinates and timing addition) changes with the change of geometry factor. This may be used for improvement of the navigational position determination stability
