Satellite constellation coverage and geometrydetermining the minimum number of satellites needed to provide a service, and their orbitsis a field in itself.

It comprises the satellite or satellite constellation and the uplink and downlink satellite links.

However, the calculation of these quantities are based on a series of measurements from one or more satellite constellations.

With continued advances in the miniaturization and capability increase of electronic technology and the use of satellite constellations, nanosatellites are increasingly capable of performing commercial missions that previously required microsatellites.
