Globalstar Network Overview
Globalstar is a Low Earth Orbit satellite constellation which provides two-way voice and data communications to satellite handsets and recievers. The Globalstar project was started in 1991 by Loral Corporation and Qualcomm, and some sponsoring investors. In February of 2000 they launched 52 additional satellites. Globalstar Has completed two of four launches on their next generation satellite. The third launch has been scheduled for December 25, 2011, and the final launch is forecast in early 2012. Globalstar's first generation constellations are still operating to provide service until that time.
GlobalStar Service Update:
Globalstar Phones will experience delays in connecting to service on average of 10 to 20 minutes with southern latitudes (below 42°) performing worse then Northern latitudes (43°to 65°). The Globalstar system has recently lost several satellites that has now affected the reliability of the service being provided to the Globalstar phones and creating gaps in service ability. Please only consider Globalstar service for casual, non-urgent communications. For Time Sensitive, On Demand Communications needs, consider Iridium or Inmarsat.
To help you plan your communications, we are providing for your convenience a web-based tool that forecasts satellite availability for your location over the upcoming 24-hour period. In no way does SatellitePhoneStore.com imply Globalstar service will be available during the predicted times.
Frost & Sullivan, an independent research and consulting firm, compared Iridium and Globalstar calls placed more than identical time periods and locations. During the study, researchers placed over one thousand phone calls using a variety of Iridium and Globalstar satellite phones. Evaluative metrics included call connection, call drop and call completion. In initial testing, analysts found that more than 99 percent of calls placed through the Iridium handset were successfully connected, compared to 51.3 percent of calls from the Globalstar handset. Tests also indicate that 98.1 percent of calls on the Iridium handset and 36.2 percent of calls on the Globalstar handset were successfully connected and completed without being dropped during a three-minute period.
