Four Globalstar telecommunications satellites blasted off Sunday from the Baikonur space center in Kazakhstan atop a Russian Soyuz rocket and were successfully placed into orbit, an Arianespace spokesman said.
The first generation of these satellites were launched in 1999 by Starsem, the Russian-European subsidiary of Arianespace from Baikonur. Four more satellites were put in orbit in May this year.
Globalstar, based in California, provides communication services to businesses, government agencies and individuals.
A second constellation of 24 telecommunications satellites is expected to go into orbit starting in 2009, using Russian Soyuz rockets but launched from a South American space center in French Guiana.
