Abstract：For acquiring the position and velocity of the mobile interference localization exactly ,the model of double‐star position system for mobile interference localization is set up .The model has three functions ,the time different of arrival (TDOA) function ,the frequency different of arrival (FDOA ) function ,and the function based on geometic relationship . TDOA is generated through satellite interference’s main lobe and side lobe signal transmitting from different satellite tran‐sponder and different downlink or uplink lines .FDOA is the Doppler frequency offset which is generated through the main satellite and secondary satellite’s different perturbations phenomena in orbit .And then ,the calculate method and steps based on the least squares method were given .At last ,this paper gives an example which demonstrates the validity of the model .
