Abstract

An emergency warning network including a base station for broadcasting a warning signal and a first, earth-orbiting satellite for receiving the warning signal and rebroadcasting such to extend the range of communications of the base station. A first substation receives the warning signal and broadcasts a first forwarding signal in response thereto to a first portable receiver. A second substation also receives the warning signal and broadcasts a second forwarding signal in response thereto via a second, earth-orbiting satellite to a first branch station. The first branch station broadcasts a third forwarding signal in response to the second forwarding signal to a second portable receiver. A second branch station also receives the second forwarding signal via the second, earth-orbiting satellite and broadcasts a fourth forwarding signal to a third portable receiver.

Claims

1. An emergency warning system, comprising:

a base station for broadcasting a warning signal;

a first, earth-orbiting satellite for receiving said warning signal and rebroadcasting such so as to extend the range of communications of said base station;

a first substation for receiving said warning signal from said first, earth-orbiting satellite and for broadcasting a first forwarding signal in response thereto;

a first portable receiver for receiving said first forwarding signal from said first substation;

a second substation for receiving said warning signal from said first, earth-orbiting satellite and for broadcasting a second forwarding signal in response thereto;

a second, earth-orbiting satellite for receiving said second forwarding signal and rebroadcasting such so as to extend the range of communications of said second substation;

a first branch station for receiving said second forwarding signal from said second, earth-orbiting satellite and for broadcasting a third forwarding signal in response thereto;

a second portable receiver for receiving said third forwarding signal from said first branch station;

a second branch station for receiving said second forwarding signal from said second, earth-orbiting satellite and for broadcasting a fourth forwarding signal; and

,

a third portable receiver for receiving said fourth forwarding signal from said second branch station.

2. An emergency warning system, comprising:

a base station for broadcasting a warning signal, said base station including;

a CPU for assimilating, editing and storing data;

a keyboard connected to said CPU for entering data into said CPU;

a monitor connected to said CPU for scrutinizing data entered into said CPU;

a printer connected to said CPU for generating a copy of the data entered into said CPU;

an RF transmitter connected to said CPU for broadcasting said warning signal; and

,

a microphone connected to said transmitter for entraining human speech in said warning signal;

a first, earth-orbiting satellite for receiving said warning signal and rebroadcasting such so as to extend the range of communications of said base station;

a first substation for receiving said warning signal from said first, earth-orbiting satellite and for broadcasting a first forwarding signal in response thereto;

a first portable receiver for receiving said first forwarding signal from said first substation;

a second substation for receiving said warning signal from said first, earth-orbiting satellite and for broadcasting a second forwarding signal in response thereto;

a second, earth-orbiting satellite for receiving said second forwarding signal and rebroadcasting such so as to extend the range of communications of said second substation;

a first branch station for receiving said second forwarding signal from said second, earth-orbiting satellite and for broadcasting a third forwarding signal in response thereto;

a second portable receiver for receiving said third forwarding signal from said first branch station;

a second branch station for receiving said second forwarding signal from said second, earth-orbiting satellite and for broadcasting a fourth forwarding signal; and

,

a third portable receiver for receiving said fourth forwarding signal from said second branch station.

3. An emergency warning system, comprising:

a base station for broadcasting a warning signal, said base station including;
