A Rapid Method For Orbital Coverage Statistics With Using Ergodic Theory
Andrew J. Graven, Alan H. Barr, Martin W. Lo
Quantifying long-term statistical properties of satellite trajectories typically entails time-consuming trajectory propagation. We present a fast, ergodic\cite{Arnold} method of an…
