The existing localization methods for an aerial moving target based on satellites are too complex and costly to be used in practical applications.A new localization technology based on two satellites for an aerial moving target is proposed.By combining two localization parameters named time difference of arrival (TDOA) between two satellites and direction of arrival (DOA) from the main satellite

the three-dimensional locations of an aerial moving target can be achieved.The three-dimensional mathematical localization model for an aerial moving target is established with the vector solution method.Moreover

for Monte Carlo analysis

the localization error model is established in consideration of many error factors.Lastly

the proposed localization technology is used in the suppositional scene which is composed of space station and one small satellite

and the numerical simulation is carried out.The simulation results show that the proposed localization technology can realize accurate estimation of the ground track and the three-dimensional position for an aerial moving target.
