Satellite Coverage Area
Satellite Coverage Area (%) of a satellite is the geographical region or area over which a satellite provides communication, broadcasting, or other services. In general, satellites are designed to cover specific regions or continents, although some satellites may offer global coverage. Here we will calculate the coverage area of the satellite for specific regions given the distance and radius.

- A is the Satellite Coverage Area (% coverage)
- β is the Earth's central angle
- s is the arc length (km)
- r is the radius of the earth (distance between the geocenter and ground station) (km)
For Example:
Consider the arc length of the earth, s = 200 km and the radius of the earth, r = 637 km
Then the Coverage of the satellite, A % = 1/2 (1 - cosβ)
= 1/2 / (1 - cos(((200*360)/(2*22/7*637)))
= 1.41525355 %
≈ 1.4153 %
