Wireless communications has been a reliable data link means in many aerospace applications, including critical ones. The major concern for using wireless links for aerospace sensors is the feasibility of their in the aerospace setting; i.e., whether wireless links will negatively affect the overall reliability and safety of the aircrafts. In a previous(More)
Wireless communications has been a preferred and reliable data transmission means in many aerospace applications, including flight-critical ones. The aerospace industry should consider replacing some aerial-vehicle sensor wiring with wireless communications; the related sensors are referred to as aerospace wireless sensors (AWSs). This replacement can lower(More)
The issue of a backup system for GPS has been discussed for years. This is particularly so when GPS became the backbone for so many systems which includes much more than just navigation. A U.S. presidential order issued in 2003 [1], required the Department of Homeland Security, DHS, in cooperation with the Department of Transportation, DOT, to develop an(More)
Recently there is increased interest in a system that would automatically track all aircraft in flight, or certainly large aircraft, continuously with complete global coverage. But, normal air traffic management, ATM, procedures perform that function. The proposed systems would track aircraft without crew interaction at a higher update rate than current ATM(More)

Aircraft Radio Corporation of Boonton, N.J., a long-forgotten entity, played a huge role in the development of modern avionics. Aircraft Radio was a wholly-owned subsidiary of Radio Frequency Laboratories, RFL, in the mid 1920's and was spun off as a separate company in 1929. Aircraft Radio developed airborne radio equipment for military and civilian(More)

When the United States entered WWII all US domestic production of automobiles, aircraft and electronics was halted and every available factory was repurposed to research, develop and produce war material. Aircraft destined for the airlines became military troop transport, automobiles were drafted into military service and any factory that could make even(More)
