The DS ('Dnepropetrovsk Sputnik') small satellite bus was developed by Yangel's OKB-586 / KB Yuzhnoye in the Ukraine for launch by the same bureau's Kosmos launch vehicles. They were used for a wide range of military and scientific research; component proving tests; and as radar, ASAT, and ABM targets.

The original DS series spacecraft made maximum possible use of a common design scheme and equipment. The sealed casing of the spacecraft consisted of two hemispherical bulkheads joined by a cylindrical center section of 800 mm diameter. The length of the cylinder was varied according to the requirements of the internal payload. The casing was filled with nitrogen, and internal trusses allowed mounting of batteries, standard telemetry equipment, and mission-specific research equipment. Sensors for the research equipment were installed on the cylindrical section or on the upper hemisphere.

Common avionics included the BKRL-E command radio line equipment developed by NII-648, the Tral-MCD radio telemetry system and Rubin-1D orbit radio control systems developed by the Experimental Design Bureau of the Moscow Institute of Energy, the chemical batteries developed by All-Union Research Institute of Current Sources.

The thermal control system used two fans, a control unit, temperature sensors and an external radiator. The DS-MT and DS-MG variants used an offset heat exchanger with an external radiator.

The antennae suite included four rod antennae, five ribbon antennae, and one slot antenna. The spacecraft had no attitude control with the exception of the aerodynamically-oriented DS-MO. The mass of the spacecraft was between 47 kg and 321 kg. Net mass of the research equipment was between 4.5 kg and 44 kg. The active life in orbit was from 10 to15 days, dictated by the payload's power consumption from the batteries (except for the DS-P1 solar-powered radar target series) .Ground control and reception of data were via the Soviet military's ground tracking, command, and control network.

The success of the initial DS-series satellites resulted in an increased demand for low-cost small satellite missions to conduct scientific research. By 1962 the number of projects assigned to KB Yuzhnoye became so great that it was decided to transfer some satellite development projects to other design bureaus (the Meteor weather satellite to Yosifiyan at the VNIIEM State Scientific and Research Institute of Electromechanics in April 1962; the Tsiklon navigation satellite to Reshetnev at OKB-10 in August 1962; and the Yantar reconnaissance satellite to Kozlov in June 1967). Even then, to cope with the wide assortment of missions being assigned, it was necessary to design an improved universal satellite bus for the more demanding missions.

A requirements document from the Academy of Sciences of the USSR stated the need for such satellites with capabilities beyond those of the initial DS series. Preliminary Design for the DS-U was completed in 1963. Yuzhnoye proposed an improved DS-U common bus produced in five primary variants:

DS-U1: Unstabilized and battery-powered bus
DS-U2: Unstabilized and solar-powered bus
DS-U3: Sun-oriented and solar-powered bus
DS-U4: Stabilized bus with a recoverable capsule. Cancelled in 1965 and never flown
DS-U5: Stabilized bus with propulsion system for correction or maintenance of orbit. Cancelled in 1965 and never flown

Yuzhnoye's history indicates that 49 DS-U spacecraft were manufactured and delivered to orbit between 1963 and 1976. This count evidently included the two Omega flights in 1963, and excludes the GVM DS-U- mass model flight in 1977. Depending on mission requirements, these satellites were equipped with supplementary three-axis spacecraft stabilization systems, or roll stability systems, or orientation of the satellite relative to the magnetic field of the Earth. Even with a common design, the workload in the design office became so great that the Minister of General Machinery issued a decree on 30 October 1965 creating a specialized satellite design office within KB Yuzhnoye. Thirty patents were received by the bureau for various new inventions required during development of the design. The DS-U also became a vital part of the Intercosmos international program. Scientific results from the series were reported at 27 international symposia and congresses, published in 95 scientific articles in national and foreign publications and demonstrated on ten international and four national exhibitions.

After five months of further work and tests to improve the reliability of the second stage, Yangel's team felt it was ready to again attempt a launch of the 63S1 booster. 63S1 s/n 6LK put a DS-2 satellite into orbit, which conducted studies of the ionosphere. This was the first successful launch of the Kosmos 63S1 launch vehicle. A decision was made after two unsuccessful launches of the DS-1 to create a simplified DS-2 spacecraft based on the equipment and structural elements of DS-1 spacecraft. The cylindrical section for mission avionics was completely omitted.

Soviet Space Plans for 1963-1964 - . Nation: Russia. Related Persons: Korolev, Smirnov, Ustinov. Program: Soyuz, Vostok, DS. Flight: Vostok 7, Vostok 8, Vostok 9. Spacecraft: Soyuz A, Soyuz B, Soyuz V, Vostok, Zenit-2 satellite, Zenit-4.
Meeting of the Interdepartmental Soviet of the Academy of Sciences reviews space exploration plans. In the next two years, 5-6 Luna probes will be sent to the moon, including soft landers with a mass of 100 kg, and orbiters to map the surface. There will be flybys and landings of Mars and Venus. Two Zond spacecraft will study the space environment out to 20 million kilometres from the earth. In earth orbit, 10 Zenit spy satellites, 10 to 12 Vostok manned spacecraft, 4 to 6 Soyuz spacecraft, and 10 to 12 Kosmos satellites will be launched. The Kosmos will fly missions in meteorology, communications, television transmission, and heliographic, and geological studies. Kamanin finds this a good program, but it nearly all relies on a single launch pad and one-time transmission of data from a few satellites. The military plan is not reviewed; it must go through the VPK Military-Industrial Commission first. An Expert Commission is to be formed on the Soyuz spacecraft. Smirnov and Korolev have dictated a letter to Ustinov asking that eight more Vostoks be built. On the other hand, some on the general staff want 60 cosmonauts trained in the next two to three years, to support 8 to 10 flights of single-place spacecraft and 7 to 8 flights of multiplace spacecraft.
