Russians? Spffft!
Like WE didnt build features like this into GPS before WE deployed it. GPS is spoofable on a digital scale. DuH !!
LORAN-C was spoofable for crying out loud. Alter the 100mHz signal by 10 microseconds and everyone in your coverage area is 60’ from where there little “smart box” told them they were.
There is nothing wrong with your GPS receiver. Do not attempt to adjust the reception. We are controlling the transmission. If we wish to make it seem like you are 1000 meters to the east of where you actually are, we will guide you there. If we wish to make you think your speed over ground is 275 kts when your stall warning is blaring, we will make your instruments read exactly that. We will control the horizontal. We will control the vertical. We can speed you on your way with pinpoint accuracy and digital precision, or guide commercial freighters into U.S. military war vessels in the dark of night, despite their best efforts to avoid it. So please set quietly, we repeat: there is nothing wrong with any of your digital equipment, smart phones, internet connected vehicles, digital assistants, etc. You are about to participate in a great adventure. You are about to experience the awe and mystery which reaches from the inner mind to – The Outer Limits.
Excellent!
We had rotating keys before this, the problem is that you need a high clearance to have one. Hell, I almost got wrote up for seeing a keying mechanism open. I was like, I can’t help my eyes.
