As jamming and spoofing of global navigation satellite system signals continue to grow, the Federal Communications Commission (FCC) today launched an inquiry to explore commercial technologies that would provide an alternative source of position, navigation, and timing (PNT) data.

“Although GPS is indispensable to America’s economic and national security, it represents a single point of failure that can be vulnerable to disruption or manipulation by our adversaries,” according to the FCC. “PNT data is integral to countless military, public safety, agricultural, and commercial activities. Because the American economy and national security depend on GPS as the sole source of PNT data, the U.S. government has shown great interest in developing resilient backups that would protect critical operations from any disruption in GPS signals.”
