Globalstar
Globalstar phones look and act like mobile or fixed phones, the difference is that they can operate virtually anywhere, carrying your calls over a secure Code Division Multiple Access (CDMA) satellite signal.
Like "bent-pipes", or mirrors in the sky, the Globalstar constellation of 40 Low Earth Orbiting (LEO) satellites picks up signals from over 80% of the Earth's surface, everywhere outside the extreme polar regions and some mid-ocean regions. Several satellites pick up a callas it is being made - this "path diversity" assures calls from being "dropped" even if a phone moves out of sight of one of the satellites. Additional advantages of using Low Earth Orbiting (LEO) satellites within the Globalstar system include no perceptible voice delay and lighter / smaller all-in-one phones. Globalstar Coverage Map
IMPORTANT TECHNICAL INFORMATION UPDATE - Two-Way Voice and Duplex Data Services
Simplex Data and Asset Tracking Services are stable and fully operational Since 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.
Future of Globalstar Services: With the launching of eight spare satellites for its existing constellation and Second-Generation Satellites Scheduled for 2009, Globalstar intends to be a viable supplier of satellite communications airtime and services.

In 2007 Globalstar satellites experienced an anomaly resulting in degraded performance of the amplifiers for the S-band satellite communications antenna, adversely affecting two-way voice and data services. Customer service continues to be available, but at 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.
