The limit of visibility depends on what factors? Considering an earth station at the equator, with the antenna pointing either west or east along the horizontal calculate the limiting angle.


Any geostationary satellite has an arc of visibility which can also be called footprint. This depends upon the height of satellite, elevation angle and area of coverage. The limiting angle = arc cos (αE/αGSO) = arc cos (6378 / 42164) = 81.3°.
