Navigational anomalies (i.e., dropouts) affect the stable operation of unmanned aerial systems (UAS) by disrupting the reliable reception of Global Positioning System (GPS) and Automatic Dependent Surveillance-Broadcast (ADS-B) data. Dropouts may result in fly away beyond radio control, flight into controlled airspace, or crashes into infrastructure. We classify dropouts under three categories - system, environment, and cyber. It is identified that dropouts affect a broad range of UAS types (e.g., low/high altitudes) and airliners. Methods to mitigate the effects of dropout are highly subjective, and should be chosen after considering based on multiple factors (e.g., cost, complexity) and alternative navigational aids (e.g., dead reckoning, visual odometry).
