Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings. like figure 1 Shown is a flow chart of a multi-satellite characteristic parameter identification and positioning method based on array dual-frequency mutual backup disclosed in the embodiment of the present invention, which specifically includes the following steps:
[0020] (1) Assume that indoor pseudolite receiving terminal A receives the transmitted signals of K pseudolites as S K , the baseband signal S' is obtained after down-conversion K , the down-conversion process is for the two frequency points to be down-converted respectively, so as to realize the separation of different frequency signals;
[0021] (2) Capture and track the signal of each pseudolite, and extract the carrier phase of each pseudolite at the same time, smooth the real-time carrier phase jump of the pseudolite through the different frequency signals transmitted by the same pseudolite, and smoo...
