Global condition of observability in the relative three-dimensional motion of two bodies
Abstract
An analysis is presented of global observability conditions for the three-dimensional motion of one body (body 1) relative to another body (body 2) stabilized in an inertial coordinate system. At small distances, commensurable with body dimensions, the type of three-dimensional motion is determined for which all 12 parameters of relative motion can be unambiguously estimated from indices of the measuring system of body 1. The theory presented here may have application to the optimal control of spacecraft.
