SAE International is the largest automotive and aerospace standards-setting body in the world. They set standards for the design, manufacturing, operation, and maintenance of automobiles, aircraft, space vehicles, off-highway equipment, trucks, buses, trains, marine craft, engines, and self-propelled vehicles.

Recently SAE began the process to develop:

 “Requirements for a Terrestrial Based Position, Navigation, and Timing (PNT) System to Improve Unmanned Vehicle Navigation Solutions and Ensure Critical Infrastructure Security”

Their rationale is:

“The Global Navigation Satellite System (GNSS) receivers used to aide unmanned vehicle navigation and critical infrastructure security can be subject to signal disruption, jamming, or spoofing. A terrestrial based PNT system that is difficult to disrupt, jam, or spoof is needed to compliment and serve as an alternative to GNSS.”
