LEO-DIVE objective is to design, develop and verify via a system testbed (STB) multi-satellite (≥2) diversity technique applicable to large LEO constellations to combat the detrimental effects such as shadowing, multipath fading and channel blockage events. Specifically, the Multi-Satellite Diversity Techniques (MDTs) are expected to improve the achievable peak data rate and the link outage probability at the UTs when at least two satellites are in visibility.

5G-GOVSATCOM targets the development and evaluation in a natural user environment of different key enabling technologies that aim to provide full integration of 5G-NTN in the EU-GOVSATCOM framework. In the radio technologies domain, 5G-GOVSATCOM targets the development of necessary adaptations and enhancements of radio access procedures to attend to geostationary mobile terminals in the exclusive governmental X-band. Furthermore, the integration of 5G-NTN user equipment with an antenna operationally focused on on-the-move and on-the-pause scenarios is planned. In parallel, in the inter-networking segments, 5G-GOVSATCOM aims to provide a seamless handover between terrestrial networks and NTN via a smart gateway while enhancing core-network functionalities. Finally, all project developments are planned to be first validated in a controlled lab with satellite connectivity and, posteriorly, experimentally tested in close collaboration with final users. These latter tests will constitute the first 5G-NTN trials with final users devoted to i) ubiquitous telemedicine in maritime areas and ii) crisis management connectivity bubble.
