Communications coverage over most land masses

About the Globalstar (and SPOT) Network

How Globalstar Coverage Works

The Globalstar satellites pick up signals from over 80% of the Earth's surface -- everywhere except the extreme polar regions and some mid-ocean regions. Its second-generation constellation enables several satellites to pick up a call, and this helps assure that the call is not dropped even if a phone moves out of sight of one of the satellites. As soon as a second satellite picks up the signal and connects with the same terrestrial gateway, it begins to simultaneously transmit. If buildings or terrain block your phone signal, this "soft-handoff" prevents call interruption.

How to Connect to the Globalstar Network

Satellites are constantly moving so if you are using a satellite phone in an area with some obstructions and some open sky, it may just take a bit longer to establish a connection, or calls might drop as the satellite passes behind the obstruction.
