Abstract: The second-order analytical state propagation under an arbitrary continuous thrust is proposed for relative motion in $J_{2}$-perturbed elliptic chief ...

Learn about the Degree of Relative Liquidity (DRL), a metric that assesses how well a company can manage short-term obligations and expenses through available cash flow.

Abstract: This article investigates the reconfiguration optimization of the formation flying in elliptical orbits. Based on the Tschauner–Hempel equations, the time-varying system has been reduced to ...

The idea of relative motion is an aspect of the theory of relativity (strictly, it’s Galilean relativity, rather than ...
