During the experiment, besides this satellite (Cosmos-119 was the first of this series), two more satellites of a similar design were launched:
- Cosmos-142 - February 14, 1967 ;
- Cosmos-259 - December 14, 1968

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 commissioned. [four]
In 1963, it was decided to create three modifications of the unified satellite platform: [5]
- 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.
Design Features
The scientific hardware complex of the Cosmos-119 spacecraft included:
- receivers "PM-4M-I", "PM-4M-II", operating at three fixed frequencies in the range 15–55 kHz;
- filter converter "FP-1";
- FI filter;
- receivers “R-2P” and “R-ZP”, providing measurement of “white noise” in the frequency band with medium frequencies of 0.185, 0.425, 3.0 and 5.7 MHz;
- filters "F-2P", "F-ZP";
- power supply unit "BP-1";
- remote sensor "4K-63";
- counter installation "1K60";
- electronic block "EB-4K".

Launch
The Cosmos-119 spacecraft was launched on May 24, 1966 by the Cosmos-3 launch vehicle from launch pad No. 86/1 of the Kapustin Yar Cosmodrome. [6]
Experiment Results
In the course of using spacecraft of the DS-U2-I series, the following scientific results were obtained:
- A useful signal was received at all operating frequencies of the equipment, and the fact of the passage of 31.8 kHz and 44.9 kHz radio waves through the ionosphere was confirmed for the first time in the world;
- The hypothesis about the possibility of the passage of ultra-low frequency electromagnetic waves through the ionosphere is confirmed;
- The data obtained made it possible to evaluate the dependence of the concentration of charged particles in the lower layers of the ionosphere on the time of day and other factors.
