Rear Adm. Lorin Selby (retired) recently wrote an opinion piece for The Washington Times on the vulnerabilities of GPS and why we need terrestrial positioning systems before it’s too late.
“Today, space is contested. GPS, the backbone of weapons systems, encrypted communications, the financial system and telecommunications networks, is increasingly at risk. Our adversaries understand this. They have built layered systems with redundancy on land, at sea and in orbit. Meanwhile, the U.S. has no terrestrial complement or backup to GPS. Worse, it’s a vulnerability we have known about for years.
Some see this as a matter of resilience. I see it as a matter of survival. If we lose access to GPS through jamming, spoofing or kinetic attack, we don’t lose just navigation. We lose timing. We lose targeting. We lose command and control. You’d better believe our adversaries understand this.“
