France's aircraft carrier located in real time by Le Monde through fitness app

Tracking an aircraft carrier should not be difficult for any state (satellite images). The fact that civilians can do it too now is interesting.

It would be another matter if that was tracking a nuclear submarine...

No, this is notoriously difficult. The earth is vast and a carrier is tiny in comparison.

Commercial satellites can get 30cm resolution images (military satellites can likely get even more high resolution).

The earth is vast, but once you pinpoint a carrier, a simple software loop should be able to track it for ever (those carrier do not move fast).

I cannot imagine this being remotely difficult for a state to have a constant pin on every large carriers sailing on earth. There even might be some civilian apps for that too.

But again, Strava and other connected + geolocation apps have been an issue for military personnel in general.

Difficult 40 years ago maybe.

I can't imagine with the satellite image and compute we have it would be difficult at all to know the real_time +- 30min location of any carrier by maybe the top 5-10 states, even at night.

Sub wouldn't get a GPS signal, luckily.
