SES and O3b Networks Offer an Essential Advantage to Customers With a Complementary Satellite Constellation

Written on 01 Sep 2015


Space is a crowded place, some say, and the closer you look from Earth the more crowded it might appear.

A cluster of more than 1,000 satellites orbits at several hundred kilometres above Earth’s surface in the so-called Low Earth Orbit (LEO). They serve the weather and earth observation tasks, and fulfil multiple purposes, from private and civil to research and military applications. The International Space Station (ISS) – close to 400 kilometres – and the Hubble telescope – our eye into deep space at 559 kilometres – are amongst these LEOs. 

There are thousands and thousands of kilometres to go through before encountering the Medium Earth Orbit (MEO), at 8,000 kilometres. Beyond that, the next sign of civilisation is far above, at 36,000 kilometres: the Geostationary Orbit (GEO), the second-most populated orbit after LEO. At GEO, there are over 400 large satellites in operation, travelling around the Earth at a speed of about three kilometres per second and thus appearing to be stationary from the Earth.
