APPLICATIONS OF THE ADMISSIBLE REGION TO SPACE-BASED OBSERVATIONS

摘要

Situational awareness of Earth-orbiting particles such as active satellites and space debris is highly important for all current and future space-faring nations. Previous research has proposed a correlation and initial orbit determination technique for ground based optical observations where multiple admissible region maps are intersected in the Poincare orbit element space. In this paper, a new application of the admissible region to space-based observations is introduced. A modification must be made to the correlation process as the observer’s state is always a valid solution. Numerical examples for several observation scenarios are discussed, including LEO-on-GEO and GEO-on-GEO observations.
