Constellation visibility from a location on Earth's surface. As of 2012, [96] the system was scheduled to have 15 satellites operational in 2015 and reach full operation in 2020 [needs update] with the following specifications: 30 in-orbit spacecraft (24 in full service and 6 spares) Orbital altitude: 23,222 km (14,429 mi)
The Jet Propulsion Laboratory built the Galileo spacecraft and managed the Galileo program for NASA. West Germany's Messerschmitt-Bölkow-Blohm supplied the propulsion module. NASA's Ames Research Center managed the atmospheric probe, which was built by Hughes Aircraft Company. At launch, the orbiter and probe together had a mass of 2,562 kg ...
JPL built the Galileo spacecraft and managed the Galileo program for NASA, but West Germany's Messerschmitt-Bölkow-Blohm supplied the propulsion module, and Ames managed the atmospheric probe, which was built by the Hughes Aircraft Company. At launch, the orbiter and probe together had a mass of 2,562 kg (5,648 lb) and stood 6.15 m (20.2 ft) tall.
Model of a Galileo satellite. This is a list of past and present satellites of the Galileo navigation system.The fully operational constellation will nominally consist of 30 satellites in Medium Earth Orbit, with 24 active and 6 spares equally divided into 3 orbital planes in a Walker 24/3/1 configuration.
