Abstract
To improve navigation support for a user in conditions of limited “visibility” of a satellite radio navigation system constellation, an algorithm for estimating a dynamic object location is proposed based on a numerical optimization method, both with and without the use of heterogeneous auxiliary information. The algorithm can serve as a backup to increase the user's navigation support stability and allows to estimate an object location with meter and even decimeter accuracy, and the object time scale displacement relative to the system scale - with an accuracy of tens of nanoseconds.
