A Fast Seamless Acquisition Algorithm for the CL Code of the L2C Navigation Signal

摘要

A new algorithm is proposed for the CL code of the L2C navigation signal. We eliminate the fuzzy search range problem by the segmentation process and superposition process, and we eliminate the fuzzy code phase problem by the parameter adjustment process. It can reduce the ambiguity threat in the acquisition process and that it can adapt to lower SNR. In addition, it outperforms the existing algorithms in acquisition precision, adaptability to SNR, processing speed and complexity.
