Abstract:
The direct Bayesian admissible region approach proposed by Fujimoto and Scheeres is an a priori state free measurement association and initial orbit determination (IOD) technique. Given a short-arc series of optical measurements, or a tracklet, a compact region in the range / range-rate space is defined based on a set of physical constraints such that all likely and relevant orbits are contained within it. The admissible region (AR) is a uniform probability density function (pdf) whose support is this compact region. Multiple ARs may be propagated to a common epoch and an a posteriori pdf directly computed based on Bayes’ rule.
