Comparison of Sigma-Point and Extended Kalman Filters on a Realistic Orbit Determination Scenario

By John Gaebler, Hur-Diaz. Sun and Russell Carpenter

Abstract

Sigma-point filters have received a lot of attention in recent years as a better alternative to extended Kalman filters for highly nonlinear problems. In this paper, we compare the performance of the additive divided difference sigma-point filter to the extended Kalman filter when applied to orbit determination of a realistic operational scenario based on the Interstellar Boundary Explorer mission. For the scenario studied, both filters provided equivalent results. The performance of each is discussed in detail
