Such snarls arise often enough with satellite signals to make it clear: Routine UAS flight beyond the line of sight (BLOS) will likely never happen with traditional GPS technology alone. To assure safe travel over long distances, unmanned aircraft systems need greater capability to ensure accurate positioning and routing.
