Unvalidated or unavailable GPS and "ADS-B In" data poses security and safety
risks to automated UAS navigation and to Detect and Avoid operations.
Erroneous, spoofed, jammed, or dropouts of GPS data may result in unmanned
aircraft position and navigation being incorrect. This may result in a fly
away beyond radio control, a flight into infrastructure or a flight into
controlled airspace. Erroneous, spoofed, jammed, or dropouts of "ADSBIn"
data may result in automated unmanned aircraft being unable to detect and
avoid other aircraft or result in detecting and avoiding illusionary aircraft.
For automated Detect and Avoid, a false ADS-B track can potentially be used
to corral the unmanned aircraft to fly towards controlled airspace,
structures, terrain, and so on. This research is necessary to enable safe
and secure automated sUAS navigation and safe and secure automated sUAS
Detect and Avoid operations.
