Creation History
In December 1959, the Interdepartmental Scientific and Technical Council for Space Research was created at the USSR Academy of Sciences headed by Academician M. V. Keldysh , which is charged with developing thematic plans for the creation of spacecraft, issuing basic thematic tasks, scientific and technical coordination of research works and the development of the upper layers of the atmosphere and outer space, the preparation of issues of organizing international cooperation in space research. [four]
MK Yangel is approved as a member of the Presidium of the Interdepartmental Scientific and Technical Council for Space Research. In the field of applied tasks, such work was entrusted to the Scientific Research Institute-4 of the USSR Ministry of Defense. [four]
In 1962, the DS-A1 , DS-P1 , DS-MT and DS-MG spacecraft were included in the program of the second stage of the launch of the 63C1 launch vehicle . [five]
The positive results of the first works, which confirmed the promise of remote sensing methods for solving scientific and applied problems, stimulated a huge flow of applications for the development of new research and development spacecraft with various target equipment on board. [6]
After the search design work on the development of a new modification of research satellites, it became obvious that due to the variety of research tasks and the differences between the requirements for a new series, it was almost impossible to develop a device of the same type. [7]
In 1963, it was decided to create three modifications of a unified satellite platform: [7]
- DS-U1 - spacecraft unoriented in space with chemical energy sources;
- DS-U2 - space-free spacecraft with solar batteries, as an energy source;
- DS-U3 is a solar -oriented spacecraft with solar batteries, as an energy source.
Small space satellite platforms became an instrumental base for organizing international cooperation in the field of space exploration under the Intercosmos program.
Design Features
The scientific hardware complex of the Kosmos-202 spacecraft included:
- BRS-2M (IS-1158M) is a high-speed radio-telemetry system with 16 sensors for measuring the vibration modes of the landing gear attachment points to the second stage of the launch vehicle and equipment installation points on instrument farms and spacecraft structural elements; [3]
- " Mayak-03 " - an improved radio transmitter.
Onboard radio engineering complex:
- “ BRKL-B ” - a command radio communication equipment, is a narrow-band receiver-decoder of signals transmitted from the Earth to convert them into immediate execution commands;
- " Crab " - orbit monitoring and remote signaling equipment is a transmitter of a highly stable two-frequency coherent radiation signal, which is used by the ground station to
determine the orbital speed of the spacecraft, as well as to transmit information from telemetry sensors;
- " Tral-P2 " - telecontrol equipment with a storage device "ZU-2S".
The flight program of the spacecraft "Cosmos-197"
Run
The Cosmos-197 spacecraft was launched on December 26, 1967 by the Kosmos 11K63 launch vehicle from the launch pad No. 86/1 of the Kapustin Yar cosmodrome. [eight]
Purpose of Flight
The satellite platform of spacecraft of the type "DS-U2-B" was intended for the following scientific experiments:
- determination of vibration overloads to which the spacecraft could be subjected when placed into orbit from the mine launch complex;
- study of the propagation of electromagnetic waves in the ionosphere and in the upper atmosphere of the Earth . [one]
The customers and directors of these scientific experiments were OKB-586 (now the Yuzhnoye Design Office ) and the Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation of the USSR Academy of Sciences (now IZMIRAN ). [one]
Experiment Results
Based on the results of the launches, the values of the levels and frequency ranges of the vibrations of the spacecraft were refined, which made it possible to refine and improve the chassis fastening of the spacecraft and calculate the permissible operating stiffness ranges. [9]
Also during the flight, it was possible to determine the electron concentration in the vicinity of the spacecraft and the properties of the ionosphere on the path of propagation of coherent waves from the vehicle to the observation point.
