Abstract

Abstract:

The high altitude spacecraft autonomous navigation and orbit determination technology based on the global navigation satellite system has higher requirements for the acquisition sensitivity of the receiver. Double block zero padding (DBZP) method is an ideal solution for unaided satellite navigation receiver weak signal acquisition. But the classical DBZP has low engineering value to create barriers for its popularization and application. With the help of matrix reconfiguration,a new BeiDou weak signal acquisition method aided by block improved DBZP is proposed based on the analysis of the function realization mechanism. The baseband signal and local pseudo-random code are reconfigurated to solve the contradiction between the block points and fast Fourier transform input points, greatly improving the efficiency of weak signal acquisition. Performance analysis and simulation results show that the proposed method can realize the signal acquisition low to 15 dB·Hz effectively without any loss of SNR, which can meet the requirement for high receiver sensitivity in high-altitude spacecraft orbit determination, and indoor and outdoor seamless navigation. The proposed method is the optimization on the level of DBZP block operation, and can seamlessly integrate with the other improved DBZP methods focusing on optimization of coherent integration scheme. The proposed method is thus of universal applicability and transplantability. Meanwhile, the idea of reconfiguration can be applied to any other global ravigation satellite system signal detection and acquisition based on code division multiple access, and can provide some reference to baseband signal processing of multi constellation navigation receiver.

Key words: global navigation satellite system, autonomous navigation, signal acquisition, fast Fourier transform, block reconfiguration
