Shelkovenkov D. Development of methods of network satellite differential navigation

Object - the process of high precision positioning using the techniques of differential navigation in case of sparse networks. The purpose - upgrading of well-known techniques and creation of new techniques and means of achievement of decimeter accuracy of differential satellite navigation and precision positioning in sparse networks with ability of maintaining both dual frequency and single frequency GNSS receivers. Methods - mathematical analysis, theory of matrices, theory of satellite navigation systems, statistical theory of parameter estimation, mathematical simulation technique. Results - new methods and algorithms of GNSS observation processing. It is introduced - into the Main Astronomical Observatory of the National Academy of Sciences of Ukraine,. Joint Stock Company "Scientific and Research Institute of Radio Measurements" and National Aviation University. Sphere of application - GNSS systems of coordinate and time service
