Description

Research Topic Description, including Problem Statement:

This research seeks an innovative approach to orbit determination of space objects. The goal is to balance observation frequency and propagation accuracy with the constraint of computing power. 

Example Approaches: 

This reference compared five techniques, specifically Least Squares, Extended Kalman Filter, Unscented Kalman Filter and Ensemble Kalman Filter, and Bootstrap Particle Filter. Ramanathan, T. V. and R. A. Chipade. (2021) “Comparative Evaluation of Statistical Orbit Determination Algorithms for Short-Term Prediction of Geostationary and Geosynchronous Satellite Orbits in NavIC Constellation.”

Linkage to current DNI’s S&T Priorities:

Develop/enhance capabilities to advance space situational awareness

Key Words:  Orbit determination, space object observation, orbit propagation, optimization, Kalman filters.
