Precise Orbit Determination for Low Earth Orbit Satellites
Author
Summary, in English
The precise orbit determination problem is to accurately
determine the position and velocity vectors of an orbiting
satellite. In this paper we review the general contents of
the orbit determination process, with particular emphasis
on Low Earth Orbit (LEO) satellites. The different orbit
determination approaches and the different force models
contained within are briefly discussed. The two main
estimation techniques, the batch least squares approach
and the Kalman filter, are reviewed and their relative
merits discussed. Numerical results are used to consider
the impact of different modeling errors on the final orbit
accuracy, in addition to errors due to the nature of near
real-time processing conditions.
