Abstract:

There is a large number of study on the signal acquisition techniques of BeiDou Navigation Satellite System（BDS）in recent years, however, few focus on the classification, summary and performance comparison. Given this situation, we study the acquisition algorithms based on the following three categorization standards: singlecycle, multicycle and auxiliary capture. On the basis of analyzing relevant methods in the field at home and abroad, we explore the hardware implementation status of capture algorithms and compare their performance. Simulation results demonstrate the advantages and disadvantages respectively. We finally point out the challenges and development trend of BeiDou system signal capture techniques in the future, hoping to provide a theoretical support in this field.

Key words: Beidou;acquisition algorithm;singlecycle;multicycle;auxiliary capture
