: the point in the orbit of an object (such as a satellite) orbiting the earth that is at the greatest distance from the center of the earth also : the point farthest from a planet or a satellite (such as the moon) reached by an object orbiting it compare perigee 2 : the farthes...
Each satellite “hangs” over the targeted service area for an 8-hour duty-cycle of its 12-hour orbit period before it whips through the perigee in the opposite hemisphere Operational Attributes The unique look angle to the satellites enables optimal service to Apogee’s target markets. The Moln...
The lowest point (perigee) of the ISS was 347 kilometers and the highest point (apogee) of the SH-7 orbit was 336 kilometers.(国际空间站的最低点(近地点)是347公里,神舟七号的最高点(远地点)为336公里。) This paper studies the applications of the APOGEE Control System to Knockdown Air-...

PerigeeVelocityBasic resources for communication satellites are communication radio-frequencies and satellite orbits. An orbit is the trajectory followed by the satellite. The communication between the satellite and a ground station is established only when the satellite is consolidated in its own orbit ...
