Two-Way Voice and Duplex Data Services - Temporary Limitations

As previously announced, many Globalstar satellites are experiencing an anomaly resulting in degraded performance of the amplifiers for the S-band satellite communications antenna. The anomaly is adversely affecting two-way voice and data services. Customer service continues to be available, but at certain times at any given location it may take substantially longer to establish calls and the duration of calls may be limited. Until the new second-generation Globalstar satellite constellation is operational, Globalstar is offering its Optimum Satellite Availability T-tool (OSAT) on its Internet site, which subscribers may use to predict when one or more unaffected satellites will be overhead at any specific geographic location.

Simplex Data and Asset Tracking Services – Fully Operational

The Globalstar constellation is completely stable and fully operational in supporting Globalstar Simplex data satellite products and asset tracking services. Recent monitoring tests indicate that the Simplex data network is currently operating at a successful transmission rate of greater than 99 percent. And because Globalstar's Simplex data products are also designed to work with the second-generation satellite constellation, they are expected to provide customers with years of high quality reliable service well into the next decade and beyond.

Spare Satellites Launched and Second-Generation Satellites Scheduled for 2010

Globalstar has launched eight spare satellites for its existing constellation with a view to reducing the gaps in its two-way voice and data services pending commercial availability of its second-generation satellite constellation, scheduled for initial launch in the second half of 2010. Globalstar will continue to operate its existing satellite constellation to provide and support services until the second-generation Globalstar satellites are available for service.”
