It’s not easy, the frequencies are all over the place, and which satellite are you going to jam? There’s tons up there and at most you’re using two (the one your RC is talking to and the one the boat is talking to), and there’s probably another dozen you have access to (it’s LOS for the entire sky).
Sufficient technology exists that without radio or satellite guidance such a ship could reach its destination using only local instrumentation and dead reckoning. If we made it to Io and transmitted back hi-res photos of the cloud canopy, we can make it to Tokyo harbor unscathed.
