AB  - Because there are different types of BeiDou constellations with participating 
      geostationary orbit (GEO) and inclined geosynchronous orbit (IGSO) satellites, 
      the maneuvering frequency of BeiDou satellites is higher than that of other 
      navigation systems. The satellite orbital maneuvers lead to orbital parameter 
      failure for several hours from broadcast ephemeris. Due to the missing initial 
      orbit, the maneuvering thrust, and the period of orbital maneuvering, the orbit 
      products of maneuvering satellites cannot be provided by the International Global 
      Navigation Satellite System (GNSS) Service (IGS) and International GNSS 
      Monitoring and Assessment System (iGMAS). In addition, the period of unhealthy 
      status and the orbital parameters of maneuvering satellites in broadcast 
      ephemeris are unreliable, making the detection of orbital maneuver periods more 
      difficult. Here, we develop a method to detect orbital maneuver periods involving 
      two key steps. The first step is orbit prediction of maneuvering satellites based 
      on precise orbit products. The second step is time period detection of orbit 
      maneuvering. The start time detection factor is calculated by backward prediction 
      orbit and pseudo-range observations, and the end time detection factor is 
      calculated by forward prediction orbit and pseudo-range observations. Data of 
      stations from the Multi-GNSS Experiment (MGEX) and iGMAS were analyzed. The 
      results show that the period of orbit maneuvering could be detected accurately 
      for BeiDou GEO and IGSO satellites. In addition, the orbital maneuver period of 
      other GNSS medium Earth orbit (MEO) satellites could also be determined by this 
      method. The results of period detection for orbit maneuvering provide important 
      reference information for precision orbit and clock offset determination during 
      satellite maneuvers.
