The position and velocity errors obtained with GRS measurements can be in the range of hundreds of kilometers. In addition, GRSS are usually not dedicated to the desired satellite. This thesis describes an alternative approach which utilizes the global positioning system (GPS) signals together with...
In general, the higher the orbit, the longer the satellite can stay in orbit. At lower altitudes, a satellite runs into traces of Earth's atmosphere, which creates drag. Thedragcauses the orbit to decay until the satellite falls back into the atmosphere and burns up. At higher altitudes, ...

Circumbinary planets, those that orbit around both stars of a central binary star system, challenge our understanding of planet formation. With only 12 binary systems known to host circumbinary planets, identifying more of these planets, along with their physical properties, could help to discern som...

Besides, these expressions can be applied not only for the case when the satellite orbit is circular and π / 2 ≤ I ≤π but for the arbitrary eccentricity (0 ≤ e < 1) and inclination (0 ≤ I ≤π). After additional transformations the final expansions for the orbital derivatives ...
