Go to topicWith the second pair of Galileo spacecraft recently launched from Europe's Spaceport there are now four satellites forming a mini-constellation enabling to check the European Navigation system in space and on the ground.
Galileo will provide several services, in particular the so-called "Search and Rescue" service, embarked for the first time aboard the 3rd and 4th IOV satellites.
