Don't miss it. Two minutes to go.

Launch has been successful. The upper stage is now in orbit and after another engine burn in around three hours’ time we will have the two Galileo satellite separation.

So daft question time.

In terms of GPS systems, we will have :

GPS (U.S version) with 30ish? satellites
GLONASS (Russian version) with 24 satellites? I read it's more suited to the higher latitudes than GPS?
Galileo (European version) will have 30 satellites as well?

That's going to be amazing, especially if they co-operate and develop a receiver that can pickup all 3 types of satellites.

USSR: 24 (27 in orbit):

I thought that GLONASS was good at high latitudes. The Galileo system will be interoperable with the US system.

Galileo launch:


Update:

Second burn completed. Separation has occurred and the two Galileo navigation satellites have been deployed. It will take two weeks to park them in their orbits.

The National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) spacecraft is due for launch on Friday (28th). It will be launched on a ULA Delta II rocket from Vandenberg Air Force Base, California at 10:48 - 10:57 BST (02:48 – 02:57 PDT).
