Development of this second generation Soviet navigation satellite system represented a collaboration between the Navy, Academy of Sciences, and Ministry of Shipping. The basis was the Parus / Tsiklon-B doppler navigation system, but allowing asynchronous operation of on-board equipment with only essential equipment receiving a timer interrupt. Development began in 1974 with some preliminary work already accomplished. The Tsikada system provided global navigation for both the Soviet Navy and commercial shipping. Prime contractor was KBPM/Reshetnev. PO Polyot, A S Klinyshkov provided synchronisation equipment. NII Radiopribor under N Ye Ivanov provided cryptography and spacecraft navigation systems. Flight trials began in 1976 under Admiral A I Rassokho. The system was accepted into military service in 1979.
