Statistical initial orbit determination
Journal of Spacecraft and Rockets, 1992For the ballistic missile initial orbit determination problem in particular, the concept of 'launch folders' is extended. This allows to decouple the observational data from the initial orbit determination problem per se. The observational data is only used to select among the possible orbital element sets in the group of folders.

Celestial Mechanics, 1969
The gaussian noise which affects tracking measurements causes an error in the computed value of the orbit parameters. This study provides a method for evaluating: (a) the length of the arc over which the satellite must be tracked; (b) the number of measurements to be made along this arc; (c) the position of the arc with respect to the orbit, necessary ...

Determination of periodic orbits
2010Periodic orbits play a very important role in many problems of Celestial Mechanics; for example, their study provides interesting information on spin-orbit and orbital resonances (see [96, 136]). From the dynamical point of view periodic orbits can be used to approximate quasi-periodic trajectories; more precisely, a truncation of the continued ...

Tracking and Orbit Determination
1987The in-orbit control of a spacecraft requires knowledge of its position in space. For geostationary spacecraft the position is required relative to Earth-centred axis systems, both inertially fixed and rotating with the Earth, the former largely for manoeuvre design and event prediction, the latter for purposes of Earth station coverage and antenna ...
