Solving navigation-temporal tasks in different coordinate systems

[摘要] Currently, lots of work is being done to improve the accuracy of navigation systems both from the hardware point of view [1-6] and from the software [7-11]. No less important issue is development of a single system within hardware and software complexes [12-14]. In this article we reveal the issues solving the navigationoral tasks in different coordinate systems. When creating multichannel GNSS receivers that implement interferometric methods for measuring spatial orientation on GLONASS and GPS signals, it is extremely important to solve navigation and time problems, especially in order to optimize the solution with missing satellite data.The article also presents proposals for the improvement of multichannel GNSS receivers in order to solve the problems of positioning in conditions of uncertainty and incompleteness of data.
