Chayka pulse

Chayka (Russian: Чайка, lit. English: seagull) is a Russian terrestrial radio navigation system, similar to LORAN-C. It is also run on 100 kHz and is described like LORAN-C by its GRI.

Chayka-Chains

At the hill - RSDN-3/10, Crimea

There are 5 Chayka-chains in use:

  • GRI 8000 — Western (European) Russia Chayka Chain (1969, RSDN-3/10)
  • GRI 7950 — Eastern Russia Chayka Chain (1986, RSDN-4)
  • GRI 5980 — Russian-American Chayka Chain (1995)
  • GRI 5960 — Northern Chayka Chain (1996, RSDN-5)
  • GRI 4970 — North-Western Chayka Chain
  • And also North-Caucasian, South-Ural (GRI 5970), Siberian, Angarsk, Sayansk, Transbaikalian, Far East chains deployed on the basis of low-power mobile stations RSDN-10.

Chayka-Transmitters

The following Chayka-transmitters work with very high power and may use as similar LORAN-C-transmitters very tall mast antennas.
