The embodiment of the invention provides a train track occupation detection method and a train track occupation detection device based on satellite positioning. The method mainly comprises the steps: satellite positioning receivers on the head and the tail of a train are used for receiving satellite ephemeris data and pseudorange data, and positioning positions of the head and the tail of the train are calculated according to the satellite ephemeris data and the pseudorange data; a positioning horizontal protection distance of the train is calculated according to a set positioning omission rate and a false detection rate; and the positioning positions of the head and the tail of the train are mapped on a track line by combining with an electronic map according to the positioning horizontal protection distance of the train, so that an occupation section of the train on the track line can be obtained. According to the embodiment of the invention, the satellite positioning receivers are arranged on the head and the tail of the train, so that the occupation calculation of the train on the section track can be completed by only utilizing vehicle-mounted apparatuses, ground apparatuses such as track circuits or axle counters are not needed, the constriction cost and the maintenance cost of the ground apparatuses are greatly saved, and the cost is greatly saved.
