Abstract

Abstract: High dynamic GPS and BD2 integrated navigation signal simulator is an efficient platform for design and validation of a high dynamic GPS and BD2 integrated navigation receiver. In this paper, we provide the technical framework and implementation about the key part of the GPS and BD2 integrated navigation signal simulator. And we mainly focus on the research of the generation of high dynamic signal, using cubic spline interpolation algorithm to reduce the amount of computation about the simulator, anti-SINC compensation filter design and a method to guarantee the coherence between channels of the simulator. Finally, the validation of the GNSS signal from this simulator is made.

Key words: GPS, BD2, GNSS, Satellite navigation signal Simulator, Cubic spline interpolation
