Extension of highly elliptical Earth orbits using continuous low-thrust propulsion [PDF]

open access: yes, 2013
The extension of highly elliptical orbits, with free selection of orbit period, using low thrust propulsion is investigated. These newly proposed orbits, termed Taranis orbits, are enabled by existing low-thrust propulsion technology, offering a ...

Pseudo-Stochastic Orbit Modeling Techniques for Low-Earth Orbiters [PDF]

open access: yesJournal of Geodesy, 2006
The Earth’s non-spherical mass distribution and atmospheric drag cause the strongest perturbations on very low-Earth orbiting satellites (LEOs). Models of gravitational and non-gravitational accelerations are utilized in dynamic precise orbit determination (POD) with GPS data, but it is also possible to derive LEO positions based on GPS precise point ...
