Apogee (satellite communications)

In satellite communications, "apogee" is the point where a satellite reaches its highest position in its orbit around Earth. For geostationary satellites, which stay above the same location on Earth, apogee refers to the highest point in their orbit during their elliptical path. Understanding apogee helps engineers manage satellite positioning and signal coverage. When a satellite is at or near apogee, it’s at its maximum distance from Earth, affecting signal timing and strength. Properly accounting for apogee is essential for reliable communication between satellites and ground stations.
