Abstract: The problem of locating a space target relatively using angle-only measurements is(investigated).These measurements are collected from multi-sensors synchronously.A differential-self-calibration method with extended Kalman filter(EKF) is proposed.The effect of the method is demonstrated by simulation,and the result of simulation shows that the good real-time(characteristic) with accurate results.
