MULTI-VARIATE GAUSSIAN PROCESS REGRESSION FOR ANGLES-ONLY INITIAL ORBIT DETERMINATION

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Vital for Space Situational Awareness, initial orbit determination is used to initialize object tracking and associate observations with a tracked satellite. These classical IOD algorithms provide only a point solution and have been shown to be sensitive to noisy measurements and to certain target-observer geometry. In this work, a multivariate Gaussian process regression (GPR) is trained to perform angles-only orbit determination. This work extends the GPR approach to accurately quantify the orbit states along with associated covariance. The numerical simulations shows that by accounting for correlations in the outputs, the GPR process provides more accurate estimate of orbit uncertainty.
