Globalstar 1

 1998-008A


The first four satellites were launched by a new Delta configuration, the 7420 with only 4 strapon boosters. A dispenser on the second stage carried two satellites in its lower deck and two on its upper deck.

The Delta depletion burn placed the second stage in an orbit very close to that planned, with a perigee of only 244 km.
