Abstract The author gives results of an experimental. investigation
on the properties of ferrites and draws many conclusions
on their measureamts. It is indicated, that many rario-
n-equency measurement methods cannot be eriployed with fer.
r:.tes, since their permeability depends substantially on
the applied field.

TIME: Study of the Earth's upper atmosphere and the cosmos
by Soviet space rockets and artificial sate'-lites
PERIODICAL: TeLfcomunicqii, no. 1, 1960, 20-25
TEXT: The article presents some of the methods used in exploring
the ionosphere and results obtained by data, supplLed from Soviet
space rocket.3 md sputniks. Data on the horizontal structure of
the ionosphere and on the effects of latitude could only be suppli(-d
by artificial satellites. One of the methods used for detemining
the ionosphere's properties was based on the Faraday effect. I"he
presence of Faraday rotation was proved by the signals from the
first two Soviet satellites. Another method was worked cut by Sov-
iet: scientists A. Alpert, F.F. Dobriakova, Ye. F. Ghudesenko aad
B.S. Shapirc (Ref. 1: Doklady akad. nauk SSSR, 120., 1958, no., 4,
pp 743-746). The method consists in denoting the distance "rm"
from the observer to the point right below the satellite, the mom-

erties of the ionosphere were also determined ',)y th-2 tretliol', of radL'~
walre refraction., This method requires simulta-icous measurements bv
optical and radibinterferometrical vieans. The first direct nicasun,
ments of the concentration of electrons in the upper atmosphere 'auck
accoffplished by an ion trap installed in Sputnik Ill. -Ano t he r me t- ~ -
od for ascertaining the characteristics of the ionospaere consisted
in determining the effects produced by the ionosphere orL t1le tralls-
mission of waves from the satellite to the ground station. Vlhen
the satellite passed through a region of high electroLi concentra-
tion, a frequency change was produced, especially ca.used by elec-
trons around the satellite. If the concentration of t',1(2 electrons
in the regi6ns penetrated by the satellite is sinaller than thit of
the regions penetrated by the satellite-Earth radius, a frequency
change is produced by the integrated effect of the electrotis locat-
ed along the radius. The method is based on t"he DoppLer effect.
Important information on the horizontal non-homogenz!ity of the ion-

determining the energy sources and the heatin;, ot the upper atmos-
phere. V.I. Krassovskiy's hypothesis (Ref. 3: Proc. I.R.E., 47,
1959, no. 2, pp. 289-296) is that it is due to heat developed by
electric currents in the ionosphere. Important resul-_z. were obtain-
ed on cosmic radiation. Great intensities of cosmic radiation were
recorded by the second artificial satellites at it time when nothing
exceptional appeared on Earth. This phenomenon was explained by
the fact that the increase was produced by small energy part:'cles
which did not reach the Earth's surface. Luminescence counters
were installed on the third Soviet sputnik. PenE!tratiag the north-
ern and southern geomagnetical lattitude of 55 - 600, the instru-
ments detected an increase in Roentgen radiation inten.3ity. Impor-
tant data were gathered by the space rocket launched January 2,

1959. At a distance of 4 - 10 Earth radii, the existence of ti'4o
zones of high radiation intensity was proved. The origin of the
Aurora Borealis was also explained. The third Soviet satellite
also proved the existence of heavy nuclei in the cosmic rays. A
Cherenkov detector recorded a particle o[ 300 Mev. Mo-1-her result
was the detection of the antipodes effect, observed at the Mirnyy
station by satellites having 20 tic transmitters. A mass spect:7om-
eter was installed in the third sputnik to determine the chemical
composition of the upper atmosphere at an altitude of 2:26 - 1000 I-on.
Ions with a mass number of 16 predominate at an altitude of 226 -
800 kin and the main gaseous component is oxygen. However, ions
with a molecular weight of 28 - 30 units were also recorded. Com-
pared with atomic oxygen, the concentration of atomic n:'-trogen is
I - 10%, depending on height, latitude and time. The third sput-
nik was also provided with a pressure g.41re which rEcorded at an
13 and at an altitude of
altitude of 260 km a density 1?f 10- 9 crP,
355 kin, a density of 9 x 10- 9 cm-3. To determine the positive
ions per volume unity, the third sputnik was equipped with ion
traps. The terrestrial magnetic field anomaly increases at an alti-

tude of 22,000 km. This may be explained by the existence of some
important currents at this altitude. The Soviet Union was able to
study by its three space rockets the magnetic field in the immediate
vicinity of the moon. It was established that there is no magnetic
field near the moon's surface which could be measured by the magneto-
meters On Doard. Data collected by the third Sputnik on m-. - crometeor-
ites at an altitude of 150 300 km showed that the number of impacts
with micrometeorites is 50 m2/sec. The apparatus measured iMPUISE'S
between 10-1 and 103 g cm. S-1. There are 8 figures and 10 Soviet-
blc;c references.
