He said that the claims it was circulating on the dark web were fake. Or, rather, the post he was replying to when he said "fake" was asking about the claims of the dark web video.
Here, a datasheet for the Quartz Rate Sensor - 11: https:// www.fbcoverup.com/docs/library/1998-BEI-GYROCHIP-Model-QRS-11-Machined-Angular-Rate-Sensor-Systron-Donner-Intertial-Division-BEI-Technologies-Inc-1998.pdf
The method of operation is rather simple - a specially designed quartz rod is set to a DC source voltage. Because of the piezoelectric effect, changes in acceleration along a given axis will create an output voltage proportional to the change.
Pin outs:
1 NC
2 Self-Test
3 +Vdc
4 Power Ground
5 BIT Output (TTL output)
6 NC
7 Rate Output
8 Signal Ground
9 -Vdc
10 Case Ground
There's not really much to hack or exploit, here. Not that I see. You need something to interpret the output signal into an angular trajectory and then derive positioning from it.
I mean, I could build a missile with it, but it seems an odd piece of technology to have the dispute over from the government.
Well, sure - it 'can' have just about anything in it.
However, it seems rather unlikely given the simplicity of the device and its size. Considering it would have to connect to an FPGA or microcontroller - I would suspect those of being the targets of an intrusion, first.
These things are getting very common, take your pick:

"Cheap-o" one, but still quite capable for the cost.

Higher end one that probably rivals our boeing one over here. Hard to tell, as there aren't exactly the best standards of what these specifications even are and comparing them is not as simple as comparing the displayed number.
This is true, but it would not be limited to the QRS-11, in that case. The other problem is that of where these systems are usually located. They are typically shielded from EMI for that very reason and tested rather thoroughly to ensure the fidelity of the signals.
