Globalstar
Globalstar phones look and act like mobile or fixed phones, the difference is your calls are carried 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 call as it is being made - this "path diversity" assures calls are not "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:
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.
Globalstar Satellite Voice & Duplex Data Service Status Update: Although in 2007, Globalstar satellites experienced an anomaly, resulting in degraded S-band satellite communications performance, Globalstar is on the brink of returning to uninterrupted, exceptionally high quality two-way voice and duplex data services in late 2012 continued through early 2013.

Reliable service will be accomplished by the completed launch of Globalstar's Second-Generation Satellites; integrating eight spare satellites to its existing constellation. Globalstar once again will be a viable satellite communications network provider.
We encourage current owners of Globalstar satphones to test their units. For inquiries regarding equipment or Globalstar services, contact Mackay or call 919-850-3100, satserv@mackaycomm.com
