Satellite-based emergency alert systems
Effective disaster relief hinges on the ability to communicate swiftly and accurately with affected populations. GNSS-based emergency alert systems, such as Galileo Emergency Warning Satellite Services (EWSS) in the European Union, J-Alert in Japan, or The Emergency Alert System (EAS) in the US, offer unique benefits. Tests in regions that are prone to natural disasters - earthquakes, tsunamis, cyclones… - have proved that the emergency management command system based on GNSS can play the role of "lifeline" in a critical moment. However, due to the inherent limitations of EWSS, adopting a multichannel approach that integrates satellite technology with other communication methods is essential.
