When Satellite Navigation Meets Satellite Communication in Low-Earth-Orbit Satellite Systems

In the realm of satellite systems, communication and navigation have traditionally functioned as separate systems, each requiring its own dedicated hardware.

However, emerging wireless technologies present a game-changing opportunity: they can enhance navigation capabilities by the Low-Earth-Orbit (LEO) satellite systems and enable integrated systems that serve both communication and navigation requirements.

This project aims to unlock the untapped potential of LEO satellite systems for Integrated Navigation and Communication (INAC), a critical step for Europe in developing cost-effective, dual-purpose satellite systems that could transform emergency services and Internet of Things (IoT) applications.The project is structured around three key objectives.

Firstly, with the aid of LEO communication satellites planned by the European Union, Work Plan 1 (WP1) will establish a theoretical framework for LEO satellite navigation by using dynamic constellation characteristics and Doppler information.

Secondly, WP2 will design a communication-aided navigation system that leverages the low-latency and high spectral efficiency of LEO communication satellites, aiming to enhance accuracy while minimizing computational demands.

Lastly, WP3 will develop an integrated system that combines communication and navigation using next-generation multiple-access (NGMA) techniques, ensuring optimal performance in both communication and navigation without compromise.

With a projected market impact potentially surpassing 10 billion Euros, this initiative stands to make a substantial contribution to the European space ecosystem, while providing groundbreaking solutions to global communication and navigation challenges.
