Determining Maneuver Orbit of GEO Using Stochastic Thrust Model

    Graphical Abstract
    • Abstract
  • The precision of GEO orbit plays an important role in regional navigation system when the hybrid constellation of GEO/IGSO/MEO was involved.Determintion of the orbit of GEO during orbital maneuver is important.A first order Markov stochastic process was used to construct the thrust acceleration model,and the correlative parameter estimation method was developed.Based on this algorithm,the TWTT(TWO-WAY TIME TRANFER) measurement was used to determinate the GEO maneuver orbit.Eperimental results show that this algorithm is remarkable to fit the maneuver orbit.
