Spacecraft: DS-1. Technology test of light satellite.

Spacecraft: DS-2. Technology test of light satellite.

Spacecraft: DS-A1.

Operational monitoring of cosmic rays, radiation from nuclear tests, and natural and artifically-produced radiation belts. Also said to have carried experiments to test communications and navigation equipment needed for command and control of Soviet nuclear forces (later used on the Uragan navigation satellites).


Spacecraft: DS-K-8. Detected meteoroid flux in near-earth space.

Spacecraft: DS-P1.

Supported developmental experiments for ABM systems. DS-type control-test complexes used for radar tests of the PVO (Soviet Air Defence Forces). Developed by V M Kovtunenko at OKB-586. As a result of flight test of the DS-P1 in 1962 the practical use of this method was shown.


Spacecraft: DS-MT. Studied variations in the intensity of cosmic rays.

Spacecraft: DS-MG. Studied magnetosphere of the earth.

Spacecraft: DS-P1-Yu.

Development of systems for air defence and the control of outer space. DS-type control-test complexes were developed by V M Kovtunenko at OKB-586. Flight tests of the DS-P1 in 1962 demonstrated the practical use of this method. In 1964 the DS-P1-Yu operational system started flight tests. It was accepted into the military in 1968 as part of the 'Raduga' complex. Used until 1978, a total of 78 launches with Kosmos-2 launch vehicles. Colonel Ye S Shchapov was in charge of Raduga development for the military.


Spacecraft: DS-K-40. Development of systems for the later operational Tselina satellites.

Spacecraft: DS-U1-A. Studied the optical characteristics of the atmosphere. Radiation observatory; 8 telescopes.

Spacecraft: DS-U1-IK.

Studies ionosphere of the earth; version used for Intercosmos internationl launches. Design work began in April 1967. Adaptation of DS satellites by KB Yuzhnoye. For the Interkosmos modifications V F Chutkin was Chief Designer and First Assistant was V S Budnik. Investigation of the characteristics of the earth's ionosphere and of concentrations of electrons and positive ions.


Spacecraft: DS-U2-M. Development tests of atomic clocks.

Spacecraft: DS-U2-V. Military technology development satellite - mission still classified.

Spacecraft: DS-U4-B. Light satellite with recoverable capsule for biological stuides. Cancelled in 1965 and never flown.

Spacecraft: DS-U4-T. Light satellite with recoverable capsule for low gravity materials and technology studies. Cancelled in 1965 and never flown.

Spacecraft: DS-U5. Light satellite with propulsion for periodic correction of orbit. Cancelled in 1965 and never flown.

Spacecraft: DS-P1-I.

Development of systems for the ABM forces. DS-type control-test complexe were developed by V M Kovtunenko at OKB-586. Flight tests of the DS-P1 in 1962 demonstrated the practical use of this method. In 1966 the DS-P1-I operational system started flight tests. It was accepted into the military in 1970 as part of the 'Raduga' complex. Used until 1978, launched by the Kosmos-2 rocket. Colonel Ye S Shchapov was in charge of Raduga development for the military.


Spacecraft: DS-U1-G. Studied the relationship between variations in the upper atmosphere and solar activity.

Spacecraft: DS-U2-D. Studied charged particle flows.

Spacecraft: DS-U2-I. Studied the influence of the ionosphere on passing VLF radio waves.

Spacecraft: DS-U2-MP. Studied cosmic dust particles in near-Earth space.

Spacecraft: DS-MO. Used in development of aerodynamic systems for stabilisation and orientation of spacecraft.

Spacecraft: DS-U3-S. Specialized orbital solar observatory for measuring solar rays in mulitple spectral zones.

Spacecraft: DS-U1-Ya. Studied charged particle flows and cosmic rays.

Spacecraft: DS-U2-GF. Conducted heliophysical studies.

Spacecraft: DS-U2-GK. Conducted complex geophysical studies of the upper atmosphere. Air density, auroral investigations.

Spacecraft: DS-U3-IK.

Measurements of the sun; used for Interkosmos launches. Design work began in April 1967. Adaptation of DS satellites by KB Yuzhnoye. For the Interkosmos modifications V F Chutkin was Chief Designer and First Assistant was V S Budnik. Interkosmos-1 was launched by a Kosmos-2 launch vehicle in October 1969. Payload included East European experiments to study solar UV, X-ray effects on upper atmosphere. Investigation of solar radiation and its effect on the atmosphere of the earth.


Spacecraft: DS-P1-M.

Target for development of ASAT systems. A lighter target that could be launched by the smaller Kosmos rocket replaced the first R-36 launched IS-P target. Developed by KB Yuzhnoye (KB-3 Section; Chief Designer V M Kovtunenko). Although it acted as a target for the IS anti-satellite system, it was designed for both anti-ballistic missile and anti-satellite testing. It was more than a passive target, including an impact registration system and elements of the hit (direction, velocity, etc.). First flight trials were in August 1970. It was in service from 1973 to 1983, at which time the Soviet Union unilaterally abandoned anti-satellite operations.


Spacecraft: DS-U1-R. Studied spectral range of the UF.

Spacecraft: DS-U2-IK.

Studied charged particle flows and the ionosphere; version used for Intercosmos internationl launches. Design work began in April 1967. Adaptation of DS satellites by KB Yuzhnoye. For the Interkosmos modifications V F Chutkin was Chief Designer and First Assistant was V S Budnik. East European experiments studied protons, electrons, alpha particles.


Spacecraft: DS-U2-IP. Studied the ionosphere and charged particle flows.

Spacecraft: DS-U2-MG. Studed the Earth's magnetic poles.

Spacecraft: DS-U2-K. Studied charged particle flows and cosmic radiation.
