The present invention provides a Beidou satellite-based initial train positioning calculation method, and a positioning system. The initial train positioning calculation method includes the following steps: S1: receiving Beidou satellite signals to acquire Beidou navigation data, and verifying the validity of the data; S2: acquiring a track electronic map file, and verifying the validity of the file; S3: based on the Beidou navigation data and the track electronic map file, selecting possible track sections of the current position of the train as candidate track sections, and putting the candidate track sections into a set TrackList; S4: determining whether the number of the candidate track sections in the TrackList is 1; and S5: according to the determination result, selecting to execute a single track position comparison algorithm or a non-single track position comparison algorithm. According to the present invention, by utilizing all-weather and real-time characteristics of satellite positioning, the initial position can be calculated in the case of not moving the train after starting, so that the carrying efficiency of vehicles can be improved.
