High-Order DDFS Applied in Simulated High-Dynamic GNSS Signal Synthesis
GNSS signal simulators are developed to obtain specific GNSS signal for research on satellites navigation. High-order DDFS synthesizer is need to meet the demand of reconstructing the signal with high-order characteristic states when the GNSS signal is received by a receiver installed on a vehicle with high-dynamic motion. The signal state vector with proper orders to represent the high-dynamic motion of the receivers PCA is determined, and a guide line to choose proper DDFS parameters is provided. The implemented GNSS signal synthesizers are verified by a simulation instance. The results indicate that the state errors of synthesized signal are blow the tolerance limits of the design.
