I have trouble believing what this page is suggesting. I saw several red flags (to me) on this page that suggests the writer doesn't know all that he leads his readers to believe on the aviation side of things.
Planes and drones don't track transponders. Period. Aircraft are required to have a transponder only when within 30 miles of the center of Class Bravo airspace (Honolulu International) or when within Class Charlie airspace (Kahului Airport). They broadcast a signal which AIR TRAFFIC CONTROL tracks. Some large aircraft have a warning system called TCAS (Traffic Collision Avoidance System) which DOES listen for transponder signals, but only to warn the crew if they're near another aircraft.
Having been in aviation for over six years, I don't know what he means by "staying on the beam". I've had to bracket NDB (Non-Directional Beacons) Bearings and track VOR (VHF Omnidirectional Range) Radials, but I've never had to "stay on (any) beam".
Furthermore, the method in which he describes the method of GPS working is incorrect. Satellites orbit the earth always remaining over the same position on earth, and are controlled by the USAF in Colorado Springs, CO. GPS works by sending and receiving signals from 3 or more satellites and timing the signals to determine a distance from each of them, then triangulating the distances and using the known positions to calculate a position on earth.
To conclude, shit happens to everyone, good AND bad. A plane crash could've killed the whistleblower. Of course there's going to be conspiracy theories. Big question is, why her, and why aren't bigger fish being targeted? I don't know what happened to her, but to have a conspiracy theory over her death is ridiculous.
