June 1999 - New York
Globalstar today announced the successful
launch of an additional four low-earth-orbiting (LEO) satellites into
space, bringing the total number of Globalstar satellites that have been
successfully launched to 24.
Globalstar's satellites, manufactured by
prime contractor Space Systems/Loral, were launched on June
10 at 9:48 a.m. EDT aboard a Boeing Delta II launch vehicle from
the Cape Canaveral Air Station in Florida.
"With only two more successful launches
of four satellites each Globalstar will have the coverage required to
initiate a regional roll-out of service in September,'' said Bernard L.
Schwartz, chairman and chief executive officer of Globalstar.
"We are very pleased with the performance
of our in-orbit satellites and with the results of our exhaustive systems
testing.''
"Hundreds of calls have been placed over
the system, in both the satellite and cellular mode, and the call quality
is excellent,'' Mr. Schwartz continued.
"Our service provider partners are
fine-tuning their marketing plans and advertising should begin at the end
of the summer.''
Increased system testing is the primary
reason Globalstar adjusted its launch schedule in April, accelerating a
previously procured Delta II from early November.
Because it can launch Globalstar's
satellites into a higher altitude, the Delta II rocket offers the
advantage of reducing the time required for orbit raising, and allowing
earlier availability of the satellites for additional system tests.
The Globalstar satellites were separated
in pairs from the upper stage of the Delta II rocket at an altitude of
1370 kilometers (851 miles) above the Earth.
Engineers at Globalstar's ground control
center in San Jose, Calif., subsequently acquired the satellites using the
six Globalstar telemetry command unit gateways located in Aussaguel,
France; Yeoju, South Korea; Dubbo, Australia; Bosque Allegre, Argentina;
Delareyville, South Africa; and Clifton, Texas.
During the next 14-17 days, Globalstar
engineering teams will raise the satellites to their operational altitude
of 1,414 kilometers (877 miles).
Launches will continue through the end of
the year, using a combination of Delta and Soyuz launch vehicles.
Upon completion, the 48-satellite
constellation will provide full system capacity and redundancy, backed up
by an additional four on-orbit spares.
The Globalstar system is designed to
provide affordable satellite-based digital voice services to a broad range
of subscribers and users.
Globalstar will meet the needs of
cellular users and global travelers who roam outside of cellular coverage
areas, as well as residents of under-served markets who will use
Globalstar's fixed-site phones to satisfy their needs for basic telephony.
