Abstract: A multi-function emergency assistance request, tracking, and communication system is defined by a Hub and Spoke concept of portable units able to communicate one to each other using satellite with global earth coverage by sending GPS coordinates and text, by which the user can create its own private network inside the satellite network. A central Server manages the private network to decide which Spoke(s) are referred to specific hub(s). Functionalities include tracking without internet access (only through satellite link), system for rapid evacuation where the spoke(s) call in the Hub and receives back the confirmation of message received and read from the hub and Command and Control center from the server where the user can track all private networks and can communicate with each device through text.
