Unmanned submarine earmarked for Irish Sea freight crossings

Surely a GPS mast shouldn't be a problem? And an IMU may be more expensive than a GPS receiver, but compared to the cost of the whole vessel, it's probably negligible.

Yeah a mast or tethered transmitter probably they way to go, but now you have the problem of operating both a submarine and a pseudo surface vessel.

Nothing insurmountable, but it's not as simple as running under everyone which is what the article implied (to me atleast).

Doppler velocity log is likely what they'd want.
