    Abstract
  •   This paper first analyzes the differences between the four satellite systems, discusses the possibility of deal with multiple satellite signal compatibly. Then, a multimode satellite signal baseband processing structure is designed with configurable idea. The acquisition of GPS L1, BDS B1I, GLONASS L1 and GALILEO E1B codes are analyzed. By setting the initialization parameters, you can configure the key parts, so that in each treatment process can handle a particular satellite signal. Finally, the simulation of partial subunit is carried out by using Verilog HDL, which verifies the feasibility of the design.
