Unvalidated Global Positioning System (GPS) and Automatic Dependent Surveillance-Broadcast (ADS-B) data poses security and safety risks to efficient UAS navigation and for detect and avoid operations. Exact causes for these navigation errors may be challenging to pinpoint depending on UAS operations (e.g., beyond visual line of sight) but can generally be classified into system, environment, and cyber categories. This review manuscript identifies risks of compromised navigational data (i.e., GPS/ADS-B) and a short survey of solutions to mitigate GPS data loss is presented. It is expected that the findings in this review will aid in understanding potential risks and mitigation solutions, and help regulatory organizations (e.g., Federal Aviation Administration) to revisit existing policies with regards to the accurate validation of GPS and ADS-B data.
