Precise Orbit Determination Based on the Unscented Transform for Optical Observations
In this study, the precise orbit determination (POD) software is developed for optical observation.To improve the performance of the estimation algorithm, a nonlinear batch filter, based on the unscented transform (UT) that overcomes the disadvantages of the least-squares (LS) batch filter, is utilized.The LS and UT batch filter algorithms are veri
