I would have thought so too but Naval Gazing has a short series [0] on why it's not as dire as one might think. An aircraft carrier's location being "secret" in this case is just one layer of the survivability onion [1] anyhow. (Caveat that as someone who takes a casual interest in this, I can't vouch for accurate this is at all.)

It is important to note the Naval Gazing article is specifically talking about the difficulties of actually targeting a ship for a successful kill rather than just tracking it. It's in response to the idea that satellites plus missiles would mean carriers could be instantly destroyed in a first round of hostilities with a sufficiently prepared opponent. Tracking is a lot easier to do than getting data fresh and precise enough to hit the ship with no other tools (eg ships already nearby that can get a live precise track vs terminal detection and guidance on the missile itself).

Also the capabilities of commercial and government geospatial systems has only continued to improve in the ~decade since the article was written.

Not hidden from nation states with access to real-time satellite imagery, but more rustic guerilla operations usually don't have such sophisticated access

Oh I get it, the onion is made of Swiss cheese.

Well everything's impossible, until its not.
