静止衛星の軌道決定精度

抄録

An analytical procedure is presented, which is able to estimate the accuracy of geostationary orbit determination as a function of the locations of tracking stations and the amount and noise-level of tracking data. On the assumption of linearized two-body orbital motion, satellite position/velocity error and station-keeping error are evaluated by covariance analysis. Examples of the accuracy estimation are shown for the cases of ranging and angle tracking, with the station location being varied as a parameter.
