The embodiment of the invention discloses a Beidou satellite orbit maneuver detection method, device and equipment and a medium, and relates to the technical field of satellite orbit monitoring, and the method comprises the steps: obtaining precise ephemeris historical data of a to-be-detected time period, determining all time intervals which are lack of precise ephemeris data and of which the continuous duration is at least a first preset duration, predicated Beidou satellite orbit data are obtained based on TLE ephemeris published before the corresponding time interval and an SDP4 model, and the time interval where orbit maneuver exists is determined according to the comparison result of the predicated Beidou satellite orbit data and precise ephemeris orbit data. And according to the broadcast ephemeris parameters in the time interval in which the orbital maneuver exists, determining a sub-time interval in which the satellite health state parameter is 0 and the continuous duration is at least a third preset duration, and outputting the orbital maneuver time interval. The orbit maneuver detection result obtained based on the method can be directly used for evaluating the availability of the Beidou satellite space signal and verifying the availability performance of the Beidou satellite space signal.
