ESA NAVISP project presents centimetre-level relative GNSS prototype work

Lunasa Space’s STING project, co-funded through ESA NAVISP, presented work on differential processing for cooperative satellites. The project aims to integrate relative-navigation algorithms into commercial off-the-shelf components and validate a prototype in high-fidelity simulation.

Why it matters: Accurate relative positioning supports in-space servicing and distributed satellite systems, where autonomous proximity operations depend on trustworthy navigation.

Impact: The official page describes objectives and maturation; exact performance data and independent in-orbit validation were not available in the public summary. ESA NAVISP
