The Orbit Determination of Leo Satellites Using Extended Kalman Filter

The Orbit Determination of Leo Satellites Using Extended Kalman Filter

We studied the nonlinear estimation problem of extended Kalman filter and applied this method to LEO satellite system. Through this method the performance of extended Kalman filter was analyzed. There were certain presumption taken; J2 and atmospheric drag were simply considered in the dynamic model...
