In light of last year’s DOT study of the vulnerability of GPS to unintentional interference and intentional jamming, Boeing and Rockwell Collins suggest that loran-C could be a viable backup for GPS. These suggestions will be presented formally at a NASA conference this month. On the avionics side, the presentation will discuss the concept of an integrated GPS/loran-C antenna and a contemporary digital loran receiver design that is compact enough to be embedded inside a GPS avionics unit.
