Mehdi Eshagh, in Satellite Gravimetry and the Solid Earth, 2021 2.3.2 Gaussian equations The Gaussian equations of satellite motion relate the temporal changes in orbital elements to the geopotential perturbation defined in Eq. (2.2)–(2.4). These equations have the following mathematical expressions...
The Lagrange planetary equations for perturbations in the Keplerian orbital elements are formulated. The formula describing the charge per unit mass, as function of the physical parameter of the problem as well as the orbital elements, were derived. The effects of the combined forces are ...
The result of vehicle burns on-orbit is very difficult to anticipate because of non-linearities in the equations of motion governing orbiting bodies. EIVAN was developed to plot resulting trajectories, to provide a better comprehension of orbital mechanics effects, and to help the user develop ...

communication channel of a down-link and allowing the ground station to receive transmission data from the orbital satellite according to the protocol through the use of an idle channel among plural channels of the up-link in response to other command from the orbital satellite through the down-...
Satellite communication systems based on the use of satellites in random orbits require large numbers of satellites to assure low probabilities of outage for the various links sharing the satellite overlay. The minimization of total cost of the satellite overlay required is expressed in terms of an ...
The system has a satellite providing multiple beams and a set of user terminals (UTs) e.g. paging/messaging-type device (16). A gateway is connected to a public switched telephone network (PSTN) and communicates with the UT over the satellite, where each of the UTs within a given ...
