>> Pretty hard to hide from a satellite I'd imagine.

Clouds. (Radar sats can see through clouds but can also be jammed.)

But even on a clear day, most of the people looking to target a carrier these days (Iran/hamas etc) don't have their own satellites. But a real-time GPS position accurate to few meters? That could be tactically useful to anyone with a drone.

An active fitness tracker might also give away the ship's readiness state, under the assumption that people aren't going to be doing much jogging while at battle stations.

Jamming is a good way to make sure everyone knows exactly where you are.

		Not so much when dealing with radar sats. A jamming signal directed at a paticular sat can blank out hundreds of square miles from the SAR radar. https://defence-blog.com/russia-is-jamming-european-space-ag...

Iran has their own satellites. They are also allied with Russia that has satellites and launch capabilities.

Russia has very limited numbers of SAR satellites, it's very unlikely that Iran has any.

Specifically, wikipedia suggests Russia has a grand total of 3 such satellites.

> Iran has their own satellites.

It's probably safe to say they have been destroyed, jammed, or spoofed since the war started.

		Not destroyed at least. Anything that big would show up pretty clearly, the US and other publish the orbital tracks of anything big enough to be a meaningful spy sat and it being destroyed would show up in that data.

		Based on what? They said it would take a few days and now they're asking for $200,000,000,000.00 to continue it, because it's not going as planned and Israel is still getting hammered: https://x.com/search?q=israel%20sirens%20since%3A2026-03-19&...

		That is not safe to say at all. There is not reason to suspect that without any sources. Messing with satellites is a taboo approaching that of nuclear, every time someone test or mention anti-satellite capabilities it has made for international condemnation. So please don't make unlikely claims up without any evidence.
