All applications of satellite navigation show a strong growth. They can now rely on four global systems (GPS, GLONASS, Galileo and BeiDou) and additional regional systems, sometimes aiming for future global extension (QZSS, NavIC).

This article is providing background and insights on the growing pressure on this limited resource, giving rise to proposals for “sharing” spectrum. How satellite navigation will survive and find the necessary spectrum resources to grow is reviewed in details in the following paragraphs.
