The Soviet Union's 'Tsikada' navigation satellites, later 'Nadezhda' also operated here also but have now been switched off.

Another former Soviet system currently operated by Russia also transmits here. The 'Parus' transmissions are Tsikada-like in content but they hide another purpose. They may have included a navigation function originally but they carry a second, clandestine, payload for communications. The 'navigation' transmissions are probably more about allowing the user to calculate where to point the transmitting aerial rather than working out their location on the Earth's surface.
