The hopes for radical change in the relationship between mobile and satellite are largely vested in the new generation of Low earth orbit (Leo) satellites.

But how many Leo satellites have launched? How much will the constellations cost? What services will they offer? Which spectrum bands will they use? How many are offering commercial services? Which are the leading firms?

Our new Leo satellite tracker answers these questions in an at-a-glance format and is part of our new Dossier covering the changing relationship between mobile and satellite.
