Open AI Summary
Summary:
This document discusses two separate topics related to Soviet research.
The first topic is a project conducted by the Institute of Terrestrial Magnetism of the Soviet Academy of Sciences. The project aims to create a map of electrical properties of soil, including conductivity, to determine the Earth's absorption of radio waves and to locate the best spots for radio transmissions. The map will also help air navigators and be useful in building pipelines and laying underground cables. Workers and students have been invited to help in collecting measurements for the map.
The second topic is about the 10th anniversary of the Irkutsk laboratory of time and frequencies. The laboratory determines local time using measurements of moving heavenly bodies and transmits exact time signals. They have recently acquired new, more modern equipment for scientific research with extreme accuracy. The laboratory was the first in the Soviet Union to use the Danjon prismatic astrolabe for astronomical measurements.

The T.pstitute of Terrestrial Magnetism) the Ionosphere
and WaYS?Eroi-F.X.66;77-Academy-of-Scienees USSR, has
designed a spectrum analyzer for determining the in-
stantaneous frequency of variable atmospheric inter-
ference signals with an average frequency variation
ratio of about 2104 c/sec.sec. The signals are re-
corded on a tape recorder and transcribed on a tape
loop (full time of rOtation, 1.5-2.75 sec). Change oft
frequency with time can be observed visually by an os-r
cilloscope.' The raster has 50 lines with each tenth
line brightened for better reading. The analyzer has
four frequency ranges (0-40 0-120 0-60 and 0-20 kc).
A block diagram of the analyzer circuit and signal '
spectrogramsare given. (Likhter0 Ya.I.0 S*14.1)Prozumen

September 1960 marked the 10th anniversary of the Irkutsk laboratory of time
and frequencies of the all-union institute of physico-technical and radio-technical
measurements. The laboratory's rather small collective determines local time by ,
measurement of moving heavenly bodies, transmit S exact time signals, and controls
transmission of such signals by domestic and foreign radio stations. The volume
of scientific research performed by the laboratory has expanded considerably in
a comparatively short time. The laboratory has been augmented by new, more modern
equipment which permits scientific work with extreme accuracy. This year, for
example, new apparatus is being used to transmit signals with a deviation from
absolute accuracy of only .0002 (two ten-thousandths) of a second. To obtain these
results, the equipment had to be improved locally, which was done by a group under
Perkhokutskiy, senior scientific worker of the laboratory. This laboratory was the
first in the USSR to begin use of the Danjon prismatic astrolabe, a device for
astronomic measuring of ephemerides. Instruments have been converted for
semi-automatic and individual observations, and much other work has been done,
