The NUMEROSO activity aims to assess the benefits of integrating Signals of Opportunity (SOOPs) with GNSS signals for navigation purposes, considering both terrestrial (such as 5G mobile or WiFi) and space-based (such as those transmitted by LEO satellites, or non-terrestrial networks) SOOPs. Leveraging advanced machine learning (ML) techniques, NUMEROSO will make use of SOOPs to enhance…

Optical atomic clocks offer the potential for a new era of timekeeping, with laboratory systems at the world’s leading NMIs already demonstrating 100x improvements in accuracy compared with the microwave fountain clocks that offer the best realisations of the SIsecond. Enhanced PNT systems with these next-generation clock technologies could facilitate GNSS constellations with significantly-…

In the LEO project the next generation of modulators integrated on a silicon nitride platform will be realized. We will use the technique of micro-transferprinting to integrate lithium niobate on top of silicon nitride waveguides. This back-end integration allows for being compatible with wafer scale processing in CMOS fabs. The modulators are targeting bandwidths beyond 100 Ghz

First time development of an on-board autonomous digital beamforming of multiple beams for small/compact new space payloads, with medium/large number of channels supported. The innovation also relies on the number of channels, dynamic beamforming, low power. The activity will review the digital beamforming requirements for GNSS-R and Radio Occultation payloads, define a digital processor…

The principal aim of this project is to explore the applicability of today optics and photonic technologies to GNSS receivers. It is not always straightforward to understand which part of an electronic system may be conveniently replaced by its “photonic” counterpart, with clear advantages in terms of performance, integration density, power consumption, weight, EM immunity and…

GNSS such as GPS are vulnerable, largely due to the tiny signal strength and the geometry of satellites in urban environments. Drone regulatory frameworks are progressing to where autonomous flight and operations Beyond Visual Line-Of-Sight (BVLOS) are a possibility, thus driving the need for reliable navigation services to complement or act as a back-up to existing ones (chiefly GNSS). Trusted…

Moon exploration is emerging as the next global strategic priority in space exploration. Several dozens of commercial and institutional missions to the Moon are planned for the coming decades, with a major contribution also expected from ESA (e.g. Orion service module, ESA participation in Gateway lunar station and contribution to multiple lunar robotic missions). In spite of the wide variety of…
