However, experts monitoring the sun's activity managed to figure out that the three BMEWS sites were in sunlight and could receive radio emissions coming from the sun, suggesting that the radars were being disrupted by the sun, not the Soviet Union.
Organizationally, ADC activated the 1st Aerospace Surveillance and Control Squadron to operate both the SPADATS Center (i.e., a name change, with NORAD concurrence, from NSSCC) and the BMEWS Central Computer and Display Facility in the NORAD COC, which featured a computer system the Display Information Processor--custom built by Radio Corporation of America (RCA).
Regarding defense of Conus from missile attack (China, Russia, Iran, North Korea are concerns), the main basing issues today have to do with the upgrading of the BMEWS radars in the United Kingdom at Fylingdale Moor and at Thule, Greenland, under Danish sovereignty.
** AUTOVON/AUTODIN = Automatic Voice Network/Automatic Digital Network; DSP = Defense Satellite Program; DEW = Distant Early Warning; BMEWS = Ballistic Missile Early Warning System; SOSUS = Sound Surveillance System; NUDETS = Nuclear Detonation Detection and Reporting System.
The BMEWS radars were also among the first contributing sensors to our space surveillance mission, and I'll talk more about that in a little bit.
PAVE PAWS deployed a far more efficient solid-state phased array technology, thereby eliminating mechanical radar components and the failure of those moving parts, and also the costly klystron transmitters at the BMEWS sites.
A year after the Thor Agreement was signed, a further inter-governmental agreement permitted one of the three ballistic missile early warning system (BMEWS) stations to be built at Fylingdales in North Yorkshire.
The other two BMEWS radars were built at Clear, AK, and Thule, Greenland.
Ballistic Missile Early Warning System (BMEWS) came on line, it detected what appeared to be a launch of intercontinental ballistic missiles from the Soviet Union.
Boyhan's experience includes work on the USAF Dew Line radar system, the BMEWS Rearward Communication System, troposcatter links including diversity techniques, an each station for the AT&T COMSTAR satellite program, Telstar 3 payload design, INTELSAT earth stations in Iran, terrestrial digital microwave for ARAMCO in Saudi Arabia, secure voice communications for AIR FORCE 1 and various intermodulation distortion studies.
