This problem can be mitigated by having a second or redundant navigation system onboard the UAS that is not reliant on GPS, which is the case with larger UAS typically operated by DOD and DHS.Įncrypting civil GPS signals could make it more difficult to " spoof" or counterfeit a GPS signal that could interfere with the navigation of a UAS. According to one industry expert, GPS jamming would become a larger problem if GPS is the only method for navigating a UAS. Low cost devices that jam GPS signals are prevalent. In a GPS jamming scenario, the UAS could potentially lose its ability to determine its location, altitude, and the direction in which it is traveling.
The jamming of a GPS signal being transmitted to an unmanned aircraft system ( UAS) could interrupt the command and control of UAS operations.
