The application of Floquet theory to the computation of small orbital perturbations over long time intervals using the Tschauner- Hempel equations

摘要: Abstract : This paper deals with a method of calculating the deviation path an orbiting body from nominal or reference trajectory. The form in which solution is cast was motivated by particular perturbation problem. Stanford University developing 'drag-free', 'dragmakeup', scientific satellite designed to follow purely gravitational orbit. consists actually two satellites: inner sphere proof mass, and outer concentric shell. relative position shell respect sensed capacitive pickoff. signals command active translation control system fires jets mounted on so that it chases without ever touching it. Thus mass shielded gas drag solar radiation pressure and, except for very small disturbances caused force interactions shell, follows
