An Ariane 5 rocket launch Tuesday added four more navigation satellites to Europe’s Galileo network with an on-target deployment following liftoff from a jungle spaceport on the northeastern coast of South America.

Unimpeded by rain showers and a dark gray blanket of low clouds, an Ariane 5 rocket thundered away from a European-run space base in the jungle of French Guiana Tuesday to place four Galileo navigation satellites in orbit, an on-target deployment that should improve the location accuracy of new smartphones around the world.

Mounted on a mobile platform, a European Ariane 5 rocket followed dual rail tracks across the Guiana Space Center in South America on the way to its jungle launch complex Monday, a day before its scheduled blastoff with four satellites to expand Europe’s independent navigation network.

Technicians working in the jungle of French Guiana have installed four new European Galileo navigation satellites on top of their Ariane 5 launcher, and filled the rocket’s upper stage with storable liquid propellants for liftoff Tuesday.
