Tselina-D Credit - Yuzhnoye

The Tselina D was the detailed observation portion of the two-satellite Tselina ELINT satellite system. Development began in the 1960's, with first launch in 1970, but major technical difficulties resulted in the Tselina-D not being declared operational until 1976. However by 1984 technical improvements allowed Tselina-D to take over the general surveillance function of the other satellite. The final launch attempt in the series took place in 1994.

The Tselina dedicated ELINT satellite system included two satellites: Tselina-O for general surveillance and Tselina-D for detailed observations. TsNII-108 GKRE (Zaslavskiy) developed the payload while V M Kovtunenko of Yuzhnoye/OKB-586 build the satellite and launch vehicle.

The first Tselina-O was launched by a Kosmos-3M in 1970. Delays in payload development and weight growth in the Tselina-D resulted in the whole Tselina system not being operational until 1976. The Vostok booster had to be used due to the higher weight of Tselina-D; this was later replaced by the Tsyklon-3 booster. Constant improvement resulted in Tselina-O being abandoned in 1984 and all systems being put on Tselina-D. In 1981 a second control and information processing center was established.

Tselina-D and -O spacecraft were operated simultaneously to maximize results. The Tselina system not only localized and classified radio emitters but also characterized their functional regimes. It also characterized command traffic from military units, allowing targeting of those units by photo reconnaissance satellites.

Tselina-D satellites were operated in six orbital planes, spaced 30 degrees apart. They would record data received, and then dump it to ground stations while passing over the Soviet Union. In the late 1980's the much larger Tselina-2, launched by a Zenit-2 booster, began taking over the task. The last successful Tselina-D launch was in 1992. By that time the constellation had been reduced to three orbital planes spaced at 60 degrees, complementing the Zenit-2 constellation in four higher-altitude orbital planes spaced 40 degrees apart.

Western observers could monitor the status of the Tselina-D satellites via their continuous-wave beacons which operated at 153 MHz.

Typical orbit: 544 km x 566 km at 82 degrees inclination.

• 1980 March 18 - Tselina-D - Program: Tselina. Launch Site: Plesetsk. Launch Complex: LC43/4. Launch Vehicle: Soyuz. FAILURE: Booster exploded on pad during servicing. Severe pad damage, 48 people killed. Cause found to be change in solder with tin to that with lead in H2O2 filters, causing decomposition and explosion.
  This was the worst disaster since the Nedelin Catastrophe on 24 October 1964. A commission of military officers and chief designers reviewed the incident and requested changes to equipment and procedures, especially as regarded liquid oxygen handling. Another source reports that the explosion occurred during the fuelling of the Block E upper stage, and was due to hydrogen peroxide being present in a lox line filter and a confusion between fuel and lox lines. This error had always been possible, but had never happened in the 20 years of use of the booster before the explosion. The launch pad was badly damaged and not put back into service until April 1983.
