Abstract: Three satellites cluster for time-difference localization is applied to find the radar beacon position on the ground.The geometry dilution of precision factor from the principle of time-difference localization derived.Then,the effects of radar beacon position,cluster geometry and satellite altitude on the geometry dilution of precision factor are analyzed.Some useful references for satellite cluster configuration are presented.
