That’s not true. Many missiles exclusively use GNSS and/or INS, for example ATACMS and MLRS.

GNSS is a general term that encompasses GPS and systems like it. GPS is the American GNSS.

GNSS is the umbrella term for satellite based positioning/navigation systems, since there’s now multiple in operation.
