GNSS is the only global, free, comprehensive technology providing absolute PNT data to users worldwide. Its limitations are known, including long life cycle and replenishment schedule, affecting their ability to adapt easily to short-term market needs and to some extent, resilience. Considering the above, alternative PNT methods and solutions have been developed or are being investigated,…

The need for high accuracy PNT in challenging environments has become obvious and, henceforth, mandatory for many applications. Currently, an accuracy target of 1 m in an urban environment seems a realistic achievement with multi-GNSS PPP or RTK capabilities. A significant R&D effort is ongoing to reach this target in operational products, using carrier phase positioning (PPP and RTK) and European…

In the last years, there has been fast progress in satellite on-board computing achieved by the satellite telecommunication industry. On-board processors are more performant, with less mass, volume and power consumption. As regards current and evolving space-based PNT data layer services (e.g. private or public GNSS data augmentations), they usually retransmit data computed on-ground via…
