- Alpha_(navigation) abstract "Alpha (also called RSDN-20 ) is a Russian system for long range radio navigation. RSDN in Russian stands for Радиотехническая Система Дальней Навигации (radiotehnicheskaya Sistema Dal'ney Navigatsii), which translates to English as \"radio-technical long-distance navigation system\".Alpha was used to determine positions of aircraft, ships, and submarines (in underwater positions). The system was developed in parallel with U.S. Omega navigational system, and also works in VLF-range. Alpha coverage is up to 10,000 km from the master station, with a position error of 2.5…7 km.The Alpha system consists of three transmitters, placed in the proximity of Novosibirsk, Krasnodar and Khabarovsk. Two other transmitters at Revda and Seyda are not currently operational as of 2010. These transmitters radiate signals of 0.4 second duration, in a 3.6 second cycle, on the frequencies F1: 11.904761 kHz, F2: 12.648809 kHz and F3: 14.880952 kHz. From the phase difference of the received signals, a location can be determined.Other alternative frequencies are F3p: 14.881091 kHz, F4: 12.090773 kHz, F5: 12.044270 kHz, F6: 12.500000 kHz, F7: 13.281250 kHz, F8: 15.625000 kHz, Fx: 12.700000 kHz.Much like the antenna masts used for the U.S. Omega navigational system, the masts of Alpha must be very tall, for technical reasons. Unfortunately, no data are available for their height.Some transmitters are being disabled as of January 2014.".
