Balanced Low Earth Satellite Orbits [PDF]
Advances in Astronomy, 2020 The present work aims at constructing an atlas of the balanced Earth satellite orbits with respect to the secular and long periodic effects of Earth oblateness with the harmonics of the geopotential retained up to the 4th zonal harmonic. The variations of the elements are averaged over the fast and medium angles, thus retaining only the secular and ...

Fuel Optimization for Low Earth Orbit Maintenance [PDF]
Journal of Astronomy and Space Sciences, 2008 The resolution of Earth images taken from a satellite has close relation with satellite's altitude. If a satellite has lower altitude, it gets a picture having better resolution.
