Feasibility of spatial vehicle localization during the atmospheric re-entry phase
Abstract
The use of covariance analysis to determine the tracking performance of a network for localizing spacecraft coming in from LEO is statistically studied. Various types of tracking data and repartition along the trajectory are taken into account along with a representation of uncertainty measurements and model parameters. The analysis is validated by real measurement simulations using numerical filtering techniques to process the data, and the problems associated with applying filter theory to the reentry problem are discussed. Numerical results showing the effects of data error magnitude, data type, and number of location observations in the resulting state estimate and its covariance are presented.
