Event Triggers in Linear Covariance Analysis with Applications to Orbital Rendezvous

摘要

We develop and document the analytic expressions of a generic event trigger for a linear covariance analysis. The event triggers are applied to the analysis of a common orbital rendezvous problem. Some unexpected results are observed and a flaw in an equation that is commonly used in standard linear covariance analysis applications is uncovered and remedied. A quantitative analysis of the effect of elevation angle triggers for various rendezvous scenarios is presented.
