Electric orbit raising and space weather
...The colour coding indicates the number of days after launch. Geostationary orbit (GEO) is indicated by a white dashed line. Electric orbit raising Satellites in geostationary orbit (GEO) are fixed at an altitude of around 36,000 km, but even they are...

Reusability is key to expanding future space launch business
...at four key segments in the commercial market: geostationary orbit (GEO), non-geostationary, low Earth orbit (LEO) constellations and other non-GEO constellations. The traditional geostationary satellite marketplace is somewhat under siege these days...

The Space Elevator – an alternative path to space?
... around a rotating celestial body or a Lagrange point. Geosynchronous equatorial or geostationary orbit (GEO), offers such an equilibrium for Earth. A body such as a TV satellite in GEO remains above the same point on the ground as Earth rotates. The...
