Third-body perturbation in the case of elliptic orbits for the disturbing body
(2008-12-01)
In the present work it is presented a semi-analytical and a numerical study of the perturbation caused in a spacecraft by a third body using a double averaged analytical model with the disturbing function expanded in ...

Swarm SCARF equatorial electric field inversion chain
(SpringerOpen, 2013-11-22)
The day-time eastward equatorial electric field (EEF) in the ionospheric E-region plays a crucial role in equatorial ionospheric dynamics. It is responsible for driving the equatorial electrojet (EEJ) current system, ...
Comparison of storm time equatorial ionospheric electrodynamics in the African and American sectors
(Elsevier, 2010-08-12)
The characteristics of storm time (corotating interaction regions (CIR)-driven storm that happened on 9 August 2008) equatorial electrojet (EEJ) phenomena and their effect on the ionospheric density structure at two different ...
Influence of nonsphericity of planetary satellites and perturbation of the third-body on the artificial satellites motion
(2011-12-01)
Some orbital characteristics of lunar artificial satellites is presented taking into account the perturbation of the third-body in elliptical orbit and the non-uniform distribution of mass of the Moon. We consider the ...

Electric fields and zonal winds in the equatorial ionosphere inferred from CHAMP satellite magnetic measurements
(American Geophysical Union, 2007-12-16)
The Equatorial Electrojet (EEJ) produces a strong magnetic signal in measurements of the low‐orbiting CHAMP satellite. Six years of data with more than 30,000 dayside equator crossings provide a unique data basis to study ...
Are plasma bubbles a prerequisite for the formation of broad plasma depletions in the equatorial F region?
(American Geophysical Union, 2013-06-24)
Formation of broad plasma depletions (BPDs) at night in the equatorial F region is understood in association with plasma bubbles. However, we report BPDs that do not show a connection with bubbles. The characteristics of ...
