| Abstract: | Beidou and GPS have different satellite signal frequency band, and some embedded designs lack essential improvements, so radi ated interference of embedded system effects signal acquisition sensitivity of Beidou receiving module. Taking B1 receiving module in Bei dou satellite guidance system as an example, this paper introduces the architecture of Beidou receiving module and the relationships be tween embedded system and Beidou receiving module. It analyzes the reasons that radiated interference caused by embedded system ex erts negative influences on the acquisition sensitivity of Beidou receiving module. |
