Kopsavilkums

Apraksts

The first radio range beacon, developed by NBS scientists, was set up at College Park, MD in 1926 where its effectiveness was evaluated by specially-equipped airplanes flying on this beacon. From 1926 to 1933 most of the radio range development program was carried on at this site, including the original work on visual and multicourse beacons, elimination of night errors, and radio receiving equipment for use with radio range beacons. The radio-beacon system was originally set up on a smaller scale at NBS in the early twenties. Confirmation of its potential utility led to the establishment of the College Park field station.
