SALICE project: Satellite-Assisted Localization and Communication Systems for Emergency Services

Future emergency systems will be characterized by the integration of meshed heterogeneous networks based on both satellite and terrestrial segments [1], [2]. In this architecture the satellite infrastructure will play a lead role because of its independence from the catastrophic event as well as its ability to deliver information over a large area, provide localization information, and collect data from the sensors deployed on the territory. Particularly, the case of natural or man-originated disasters raises the urgent need for immediate restoration of a minimal level of connectivity in order to provide first response to emergency requests, coordinate rescue teams, and allow survivors to communicate with the external world [3]. On the other hand, the cooperation among communications and navigation systems, components, and services will be key features of future emergency systems. The integration of navigation and communication systems allows the exploitation of both navigation information for communication purposes (optimization of communication techniques, interference reduction, and location-based information services delivery) and communication support for navigation purposes (high precision localization and cooperative positioning) [4], [5]. The main goal of the Satellite-Assisted LocalIzation and Communication Systems for Emergency Services (SALICE) project was the investigation of the open issues related to this scenario, the proposal of a proper system architecture, and the establishment of a definition of the innovative solutions that have proven beneficial for emergency operators.
