Orbit Determination And Parameter Estimation: Extended Kalman Filter (EKF) Versus Least Squares Orbit Determination (lSQOD)

Abstract

In the age of intensive exploring of the solar system, many professionals and non-professionals become interested in calculating the basic data regarding the solar system planets. We have considered some concepts of the physical ephemeris calculation for the natural and artificial solar system bodies. As an effective result, during a conference session, we presented an oral explanation of an interactive program for practical calculation of the physical ephemeris of the planets as a problem of general interest. As a specific example, in this article the readers can find the theoretical and practical elements and procedure explanation for two useful methods of the satellite orbit determination: LSQOD and EKF.
