Satellite system and method of deploying same

A medium earth orbit satellite communications system, comprising:

• a plurality of medium earth satellites deployed at an altitude such that the path of the plurality of medium earth satellites is substantially not in the line of sight of geostationary satellites.

A method of increasing the size of a satellite constellation in response to demand, comprising:

• initially deploying, in a medium earth orbit, a minimum number of satellites necessary to achieve desired coverage, and
• in response to increased demand, subsequently deploying, in the medium earth orbit, in at least one subsequent deployment, additional satellites, such that said additional satellites are interleaved with said minimum number of position-adjustable satellites.
