GPS is passively received.
Slap an AirTag on it at least.
I’d imagine they would have RTK with a CGA response on something worth $80M. I put that in a drone for $250. But idk if it would be able to respond underwater. You’d think they’d have a track up until it went under.
I’m not an engineer, or have any real qualifications on the subject. But I’m guessing you would want to cut all transmissions you can from a stealth jet.
RTK requires a separate receiver which is located nearby and has a comms link (unlikely for a fast moving attack aircraft) and only reduces the accuracy from meters to cm. Not sure there’s much need there.
