Associated space launch
The Globalstar global mobile communications network offers global, digital real time voice, data and fax via a constellation of 48 minisatellites. The constellation operates in a 1410 km orbit inclined at 52 degrees, and will also have 8 spares. The satellites were built by Space Systems Loral and Alenia Aerospazio in Rome, Italy.
DELTA 2 R/B was lifted into orbit during the mission ‘Delta 7420-10C | Globalstar 25,47,49,52’, on board a Delta 7420-10C space rocket.
The launch took place on June 10, 1999, 1:48 p.m. from Space Launch Complex 17B.
