The aim of the LIFELINE project was to perform a feasibility study of a Relativistic Positioning System. Nowadays, all GNSS in operation are based on Newtonian physics and rely on global reference frames fixed to Earth. Relativistic effects are treated as deviations that need to be corrected. A practical RPS would consist, for example, in a constellation of satellites, each one broadcasting not only its General Relativity coordinates (proper times or other observables) at emission but also the coordinates that it receives from the other satellites.

This project was intended to contribute to the implementation of the e-navigation concept (as defined by IMO, Ref. 2.2.6), with primary focus on the navigation in restricted waters, such as harbours, lagoons or regions where the traffic congestion can create conditions for accidents or inefficient operations.

GALIST is a project that supports the traceability of food products linked to their position and the occurrence of significant events (e.g. labelling, packaging, shipping). The system is based on an innovative concept that uses GNSS combined with ADSB data, which is provided by airplanes. The GALIST project uses, in fact, a double-certification approach – based on a proprietary algorithm – to keep track of products.

Indonesia is periodically affected by severe volcano eruptions and earthquakes, which are geologically coupled to the convergence of the Australian tectonic plate beneath the Sunda Plate.
