GPS ENABLED EMERGENCY MESSAGING SYSTEM
First Claim
1. An apparatus for generating an emergency broadcast message for broadcast by satellite, comprising:
- a geographic region identifier module that receives input describing a geographic area within which reception of the emergency broadcast message is intended and generates a geographic identifier indicative of the geographic area within which reception of the message is intended;
a message generator module that receives message content for inclusion in the emergency broadcast message and receives the geographic identifier from said geographic region identifier module, said message generator module generating the emergency broadcast message including the message content and the geographic identifier; and
a network connectivity module that receives the emergency broadcast message and supplies the emergency broadcast message to a communication network for delivery to a ground-based satellite uplink facility.

Abstract
A GPS enabled Emergency Messaging System (GEMS) includes: Emergency Response Centers (ERC'"'"'s) for defining emergency broadcast messages directed to specified geographic areas; a GPS Control Segment (CS) facility that receives messages generated by the ERC'"'"'s and coordinates uplink and downlink communications with orbiting GPS satellites; a GPS Space Segment (SS) that includes the multiple orbiting GPS satellites and that receives emergency messages from the CS facility and broadcasts transmissions containing both GPS navigational information and an emergency broadcast message; and GEMS-enabled user equipment that is capable of receiving and processing broadcast emergency messages. The system permits emergency messaging data to be superimposed on the existing GPS signal structure and delivered to users with GPS receivers capable of receiving the superimposed messaging data.

4. An apparatus for uplinking an emergency broadcast message to a satellite for broadcast by the satellite, comprising:
-
a network connectivity module that receives the emergency broadcast message from a network connection;
a message traffic controller module that assesses satellite resources associated with broadcasting the emergency broadcast message and determines whether to approve the emergency broadcast message for uplinking to the satellite; and
an upload generator module that generates a satellite command instruction containing the emergency broadcast message and transmits the satellite command instruction to the satellite in response to said message traffic controller approving the emergency broadcast message for uplinking to the satellite. - View Dependent Claims (5, 6, 7, 8)
