GNSS (Navstar GPS (USA), GLONASS (RU), Beidou (CN), Galileo (EU)) might encounter jamming or spoofing. See https://gpsjam.org/ for daily maps of interference.
note: Galileo is now hardened by authentication (OSNMA) https://insidegnss.com/osnma-necessary-but-not-sufficient-for-gnss-security/
This page lists some alternative (marine) navigation strategies:
