Globalstar SPOT is the world's first satellite messenger, SPOT sends your exact GPS coordinates and selected messages over commercial satellites to tell other of your location and status.
SPOT works around the world, independently of cellular networks.
SPOT features four key functions that enable users to send messages to friends, family or emergency responders, based upon varying levels of need:
FEATURES
- Alert 9-1-1: despatch emergency responders to your exact location
- Ask For Help: request help from friends/family in your exact location
- Check In: let contacts know that you are OK
- Track Progress: send & save your location & allow tracking via Google Maps
SPOT uses the GPS satellite system to determine a user's location and the SPOT satellite network to transmit that location and the user's status.
The SPOT satellite network is a commercial satellite network with a proven 99.4% reliability rate while processing over 6 million messages a month - the equivalent of 2.3 messages per second.
SPOT utilises the Globalstar network.
