3/14/2024 0 Comments Nasa vlf receiver![]() While the nature of this memorandum is speculative because of the lack of confirming data, the receiver method proposed has evolved from related principles which have been applied to the operating OMEGA-VLF navigation system. Further study of the actual transmitted signal format is warranted. One conclusion is that U.S.S.R.-VLF receivers might be fabricated at quite low cost making it possible for all persons in remote areas each to have his own private positioning aid. The stability required of the local reference oscillator is probably much less critical than for other VLF receivers because of the signal format. Of interest are receiver methods requiring processor gate complexity similar to a digital wristwatch including the use of mass-produced low frequency quartz crystal reference oscillators. From this data it appears possible to derive receiver operation modes and some implied reasons for the unique choice of the time-multiplexed frequency time base used. Beukers has reported some information on the signal format, frequencies used, and the probable radiated power levels. has a VLF navigation system similar to OMEGA. Assise, France -FUB), or at 24.0 kHz (Balboa, Panama -NBA). These five wide-dynamic-range (52dB), narrowband (160 Hz), VLF receivers received at frequencies of 16.8 kHz (St. This far exceeded the 3-month planned lifetime. ![]() Possible methods for USSR-VLF navigation receivers The U.S.S.R. The experiment failed on August 26, 1968, after 30 months of operation. ![]()
