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 key thematic tasks, and coordinating research work and the development of the upper atmosphere and outer space, the preparation of questions of the organization of international cooperation in space research. [four]
The member of the Presidium of the Interdepartmental Scientific and Technical Council for Space Research is approved by MK K. Yangel . In the field of applied tasks of carrying out such work, NII-4 of the USSR Ministry of Defense was entrusted. [four]
In 1962, the spacecraft “ DS-A1 ”, “ DS-P1 ”, “ DS-MT ” and “ DS-MG ” were included in the second-phase launch program of the “ 63C1 ” launch vehicle . [5]
The positive results of the first works, which confirmed the prospect of remote methods for solving scientific and applied problems, stimulated a huge flow of applications for the development of new research spacecraft with various target equipment on board. [6]
After conducting 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 the 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 the unified satellite platform: [7]
- DS-U1 - a spacecraft non-oriented in space with chemical energy sources;
- DS-U2 - a spacecraft not oriented in space with solar batteries, as an energy source;
- DS-U3 is a Sun- oriented spacecraft with solar panels, as an energy source.
Small space satellite platforms have become 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 Cosmos-95 spacecraft included:
- “ BRS-2M ” (IS-1158M) - a high-speed radio telemetry system with 16 sensors for measuring vibration modes of the points of attachment of the chassis to the second stage of the launch vehicle and points of installation of equipment on instrument farms and structural elements of the spacecraft; [3]
- " Mayak-03 " is an advanced radio transmitter.
On-board radio complex:
- “ BRKL-B ” - command radio link equipment, is a narrow-band receiver-decoder of signals transmitted from the Earth to convert them into immediate execution commands;
- “ Crab ” - the orbit and telealarm radio monitoring equipment is a transmitter of a highly stable two-frequency coherent radiation signal, which is used by a ground station to
determining the orbital speed of the spacecraft, as well as for transmitting information from telemetry sensors;
- " Tral-P2 " - telecontrol equipment with a memory device "ZU-2S".
Cosmos-95 spacecraft flight program
Launch
The Cosmos-95 spacecraft was launched on November 4, 1965, with the Cosmos 11K63 launch vehicle from launch pad No. 86/1 of the Kapustin Yar Cosmodrome. [8]
Purpose of Flight
The satellite platform of the spacecraft type "DS-U2-V" was designed to conduct the following scientific experiments:
- determination of vibrational overloads to which the spacecraft could be subject to launch 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 Yuzhnoye Design Bureau ) 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 clarified, which made it possible to finalize and improve the spacecraft mounting chassis 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 propagation path of coherent waves from the device to the observation point.
