Regarding technical viability: what's their luminosity? It's quite hard to compete with solar radiation. x-rays also can't be resolved (there's no small x-ray lens), so I assume you need some kind of shielded detector, which should be vulnerable to all kinds of radiation sources and isotropic -- so a lot of noise and no resolution.
Regarding jamming resistance, if the signal is weak enough considering it's lack of resolve-ability (contrary to advanced GPS antennas which reject ground sources due to multipath and interference), it should be easy to direct an x-ray source at a receiver it and neutralize it.

Receivers are entirely passive. You would need to know with certainty location of the receiver to attempt to jam it, unless you're just using an omnidirectional transmitter (hello inverse square law!).
- darkmighty 12y agoYou could aim an x-ray beam at an airplane or car for example. Even with an omnidirectional antenna the signal of distant x-ray sources is so faint you most certainly could overpower it for large distances. I also didn't realize but in this case unless the x ray sources have very specific, high frequency, detectable temporal radiation patterns you'd rely primarily on their location, and as I've said it's hard to resolve x ray images.
