Periodic Relative Motion Near a Keplerian Elliptic Orbit with Nonlinear Differential Gravity approximations found in the literature, because the semimajor axes of the satellites are shown to be matched to the second order in the small parameter... P Sengupta,R Sharma,SR Vadali - 《Journal of Gui...
In fact, they are also orbiting the Earth in a distant Keplerian ellipse. Because of their intrinsic orbital instability, in the orbit prediction the initial errors propagate more prominently than those of the normal orbiting satellites, this requires special attention in the orbit design, maneuver...
One method uses the law of Keplerian orbit to compute the period from the semimajor axis which are given in the broadcast ephemeris, and the other method finds the actual repeat geometry for a selected location and identify the associated time shift [15]. As GEO satellites move repeatedly in...
