eh you normally track a drone from air/ground by heat signature but these have military countermeasures from all vectors so they are invisible when trying to track by conventional methods.  there's many other tracking methods like rf you can literally reverse engineer the guy's command pad he's using while the drone is in use (russians did this in ukraine and posted many catbox vids about it here). these drones are not communicating at all actually so can't see the starlink gps guidance they're prob using as traffic is being hidden somehow like you can rewrite a protocol and change it slightly so starlink sends command to land station which then relays to drones with 'invisible protocol'.  another method is you can get close enough to ping the thing with active ir systems that use short wavelength infrared light that is reflected back. these drones have a counter that ir doesn't work like some kind of jamming or special material. finally there is micro-doppler where you detect fast movement using radar that's how all anti-uav detection grids work so you don't get triggered by a bird and none of these drones set those off. your military could solve this in a weekend by shooting one down and then reverse engineering it
