This paper introduces the concept and benefits of using next generation Global Navigation Satellite Systems (GNSS), such as the Japanese Quasi-Zenith Satellite System (QZSS), for the provision of emergency information and warnings. The Japanese GNSS-based warning system can be tailored to transmit context-sensitive messages according to people’s location and situation through GNSS receiver terminal embedded in mobile phones and car navigation units. This real-time provision of emergency warnings using satellite-based technologies is not constrained by the limitations of ground-based communication technologies. This enables people to obtain necessary information anywhere (outdoors) and anytime during times of disaster. Satellite-based warning systems could also be integrated with existing warning services and be used as a complementary technology. This paper describes a collaborative project with Japan on the potential utilisation of QZSS for emergency alerting and warnings in Australia.
