Title: Simulation and Analysis of Integrated Orbit Determination of Satellites Constellation
Abstract: For format flying satellites or satellites constellation,the autonomous orbit determination and the high orbital accuracy is required.To meet this require,a new method of the integrated orbit determination of satellites constellation(IODSC) or format flying satellites was proposed,based on development of the satellite-to-satellite tracking(SST) measurement models and orbital dynamical model,the fusion of SST observation data and ground-based tracking(GBT) data,and proper categorization of the orbital parameters,dynamic parameters and kinematical parameters.The improvement of the orbital accuracy was analyzed theoretically.Finally some simulation was made and its results were evaluated.It verified that the new method could decrease dependence on ground tracking,and could improve the orbit determination accuracy obviously,especially the relative orbit accuracy among satellites.
