This is a simple geosynchronous satellite coverage slide rule. It calculates the elevation angle for a given latitude and longitude on the earth, to correctly point to a geosynchronous satellite at another longitude. It also shows graphically the coverage area on the earth for a satellite at a given longitude in geosynchronous orbit, and whether or not the satellite will be in view.
If authorized, at start the app will drop a pin on the map with the current users location. Long press to add a pin at a different location. Drag the pin to the latitude/longitude desired. Then slide the screen to place the satellite at the correct longitude. Elevation angle is computed based on location of the pin and location of the satellite.
