Editor’s Note: We really like the author’s admonition to “Treat GPS like Reagan treated Russia: Trust but verify.” GPS jamming and spoofing are poorly recognized cyber-security problems and show infrastructure shortfalls.
Cyber-security because they interfere with end-use devices, information technology pathways, and can plant bad/hazardous information in data bases. They show problems with our IT and other infrastructure by demonstrating how dependent all sectors are on GPS time and location services.
