Techniques that increase the confidence of ADS-B afford opportunities to equip UAS and other aircraft in the NAS with a reliable tool for air traffic management in the near and mid-term timeframe. Correcting limitations in ADS-B provides an overarching goal of NASA to safely integrate UAS into the NAS, while increasing automation, tracking and situational awareness for all participants. A low-CSWaP solution that removes false GPS sources (reflections, jamming, spoofing) expands the usefulness of ADS-B for UAS flying in urban areas.
Higher integrity GPS can positively affect a multitude of non-NASA applications. For the FAA, ADS-B could be a more "trusted" resource, as one can verify the position of the broadcasted source. For users of GPS technologies in urban environments, this elegant solution to removal of reflections would enable a higher fidelity of GPS for use in navigation, cell phones, and future UAS operations.
