ABSTRACT:
A telematic emergency communication system is provided. The system includes a user terminal that generates emergency communication signals within an emergency signal band. A spacecraft network has a first emergency mode receiver and attempts to receive the emergency signals via a spacecraft. A terrestrial network has a second emergency mode receiver and receives the emergency signals when the spacecraft network is unable to sufficiently detect the emergency signals and routes the emergency signals to a control center. A method of performing the same is also provided.
