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…

The Long-Term Forecast of Station View Periods for Elliptical Orbits
Andrew J. Graven, Martin W. Lo
In a previous paper, using ergodic theory, Lo [1] derived a simple definite integral that provided an estimate of the view periods of ground stations to satellites. This assumes th…

Density of States Graph Kernels
Leo Huang, Andrew Graven, David Bindel
A fundamental problem on graph-structured data is that of quantifying similarity between graphs. Graph kernels are an established technique for such tasks; in particular, those bas…
