In early 2006 the satellites were removed for post-storage testing in preparation for flight. This testing was performed by Space Systems/Loral at its manufacturing facility in Palo Alto, California and by the company's subcontractor, Thales Alenia Space, at its production facility in Rome.

A total of eight ground spares are planned for launch this year to augment the existing first generation Globalstar constellation of 40 LEO (Low Earth Orbit) satellites. The Globalstar constellation has provided worldwide telephone and data service, especially for remote areas beyond cellular and landline service, since 1999.

"Space Systems/Loral design and engineering oversight has been crucial to the preparations of the four ground spares that are scheduled for launch later this month," said Jay Monroe, Chairman and CEO of Globalstar, Inc. "As the architect for our first generation constellation of satellites, Space Systems/Loral brought significant advances to two-way voice and data satellite service."

Space Systems/Loral designed autonomy features into the Globalstar LEO satellites that simplify ground monitoring and on-going operation of these satellites. With on-board orbit determination, the satellites eliminate the need for ground operations to perform extensive measurements to determine their exact position in space.

"Our ongoing association with Globalstar demonstrates our flexibility in helping satellite operators meet their business objectives," said John Celli, president and chief operating officer of Space Systems/Loral. "We recognize the value of bringing communications to remote areas and are pleased to see these ground spares put into use."
