The present disclosure relates to a satellite orbit propagator using ship automatic identification information and a control method thereof, including acquiring automatic identification system (AIS) data during a predetermined period of time, performing a validation test on the AIS data acquired during the predetermined period of time, converting the AIS data determined to be suitable through the validation test, from an earth coordinate system into an inertial coordinate system, and estimating a position and a velocity of a satellite by using the AIS data converted into the inertial coordinate system and a predetermined orbit propagator model. According to the present disclosure, there is an advantage in that the orbit can be determined using the AIS data when a satellite-mounted GPS receiver malfunctions or a GPS satellite signal reception rate decreases. In particular, while the precision is lower than that of the existing GPS-based orbit propagator, there is an advantage that it is useful for determining the initial orbit after launching a satellite.
