ROME, ITALY—The Italian aerospace and defense company Finmeccanica will donate ground sensors and satellites to the project “Pompeii: Give it a Future.” The technology will be used for three years to assess the instability of the site and set up an early warning system for possible collapses. The company will also supply security guards with radio equipment and smartphone apps to improve their communication and pinpoint their position on the site. “We are offering our technology for the service of the country and its heritage,” Finmeccanica’s chief executive Alessandro Pansa told Phys.org.
