The Radiation Environment in Low-Earth Orbit
Radiation Research, 1997The radiation environment in low-Earth orbit is a complex mixture of galactic cosmic radiation, particles of trapped belts and secondary particles generated in both the spacecraft and Earth's atmosphere. Infrequently, solar energetic particles are injected into the Earth's magnetosphere and can penetrate into low-Earth orbiting spacecraft.

Kinematic Orbit Determination for Low Earth Orbiters (LEOs)
2002Kinematic point positioning of a Low Earth Orbiter (LEO) using GPS data is one possibility to get precise orbit information. This approach is followed at the Astronomical Institute of the University of Bern (AIUB) as an alternative to the dynamical orbit determination.

Low earth orbit resistant siloxane copolymers
Journal of Applied Polymer Science, 1996Two classes of siloxane copolymers were evaluated for their resistance to the low earth orbit (LEO) environment. Poly(imide–siloxane) (PISX) copolymers were used as the resin for PISX–carbon fiber composites. These composites were exposed to the LEO environment, for 50 h, as part of the “Effect of Oxygen Interaction with Materials” (EOIM-III ...

Low Earth Orbit Satellite's Orbit Propagation and Determination
2014Abstract : This paper represents orbit propagation and determination of Low Earth Orbit(LEO) satellites, which is immediate orbit satellite positioning. Beiseds, satellite global positioning system (GPS) configured satellite receiver provides position and velocity measures by navigating the filter to get the coordinates of the orbit propagation (OP ...

Low Earth Orbit Satellite Radio Networks
1997A global phone company may sound a curious statement in an industry still dominated by state-owned monopolies which mainly work within their national borders. But it is a concept whose time has come as, practically everywhere, governments either privatize or think of privatizing and deregulating their phone markets.
