The transfer orbit is elliptical in shape with low attitude at perigee, and the apogee of the geostationary orbit attitude. The apogee of the parking orbit depends on the injection velocity applied at perigee. Simulation approach of injection velocity at perigee to attain different apogees, ...

Satellite INTERCOSMOS-24 ``ACTIVE'' was launched on September 30 1989, with an initial apogee 2500 km, perigee 530 km and an orbital inclination of 82.2掳. Under ``ACTIVE'' project, a wide number of plasma diagnostics instruments were especially designed to study the ionospheric response to ...
Unfortunately, when the parent orbit has small eccentricity or the breakup occurs either near apogee or near perigee, the computation of radial component of velocity increment encounters a singularity and hence is prone to errors because of imperfect orbital element data. In another method, velocity ...
