The results of the analysis of creation simulators of navigation signals are presented. The principles of the design of systems for testing and ground debug of spacecraft’s navigational receivers are discussed. Present and promising methods of a navigation signal forming in existing simulators are considered. The approach for multi-channel simulators development based on FPGA and bus-modular systems debug is presented. The way of implementation of the navigational processor on-FPGA chip is suggested. A promising solution for the combined circuit simulator of orbital navigation receivers is proposed.
