What this repo is for
Detect when an autonomous vessel or submersible is drifting toward navigation failure.
Focus • GPS or inertial drift • current vs thrust • heading stability • obstacle detection alignment
Why it matters Marine autonomy fails gradually. Early drift signals appear before loss of course or collision.
