1.INTRODUCTION
The basic scientific task which has
to be solved by the “Chibis-M”
satellite scientific instrumentation KNA “Groza” - is the study of the
process of the development of the
stepped leader of high-altitude
lightning in the high electric fields.
Plasma-wave experiment on the micro-satellite “Chibis-M” is aimed at the
solution of fundamental problem - a study of the interrelation of the plasmawave processes connected with the manifestation in the ionosphere of
solar - magnetosphere - ionosphere - atmosphere connections and the
parameters of space weather. Specific fundamental problem is the search
for universal laws governing transformation and dissipation of plasmawave energy in the magnetosphere - ionosphere system.

2.SPACE WEATHER
Long-wave electromagnetic radiation is used for studies of plasma
processes in space and it plays the same role as seismic waves for studying
of the Earth’s structure. In comparison with the electromagnetic processes in
other regions of physics waves in plasma possess a number of the specific
characteristic features. The fundamental importance is a resonance effect
which appears as a result of waves and particles interaction, conversion of
modes, formation of resonators and waveguides. Because of resonance
effect ultra-low frequencies waves transfer information about the dynamic
phenomena in the near-earth outer space and the upper atmosphere. In this
case they reach sufficiently large amplitudes in order to have noticeable
influence on the flows of plasma and to effectively accelerate electrons in
the magnetosphere. It is recently shown that by the disturbance of plasma
are accompanied not only magnetic storms but also the ground-based
geophysical phenomena connected with the large ejection of energy explosions, hurricanes and thunderstorm, earthquake etc.

We are oriented [2] to the study of the processes, proceeding at the heights to 20
km, with the aid of the micro-satellite, which is found on the height of ~500 km,

Thunderstorm process
The magnetic- wave complex is an additional payload which does not enter
into the main payload for the registration of “event” - stepped lightning leader,
- but its onboard processor - PSA - will use the produced by this payload
strobe for the fixation of generation in this case of EM radiation in the range
10-2 - 2*104 Hz (ULF-VLF). It is known that the EM radiations generated in
the basic phase of the lightning discharge called whistles are recorded in
VLF frequency range and are observed by the satellites already long ago.

• Scientific Research Institute of Nuclear Physics
MSU, Moscow;
• Physics Institute im. P.N. Lebedev of the RAS,
Moscow;
• Lviv Centre of Spase Research Institute of NANUNKAU, Lviv, Ukraine;
• Etvosh University (Budapest, Hungary)
developed the model composition of the complex

Using a large experience of basic space research,
IKI, together with the cooperation pointed out
above, approached the creation of CSI (12.5 kg),
which includes:
• RGD - Roentgen - gamma detector (range of Xray and gamma emissions - 50-500 keV);
• DUF - Ultraviolet detector (range of ultraviolet
radiations - 300-450 nm);
• RFA - Radio-frequency analyzer (20-50 MHz);
• DPC - Camera of optical range (spatial resolution
300 m)
• MWC – Magnetc - wave complex (0.1-40 kHz).

4. REGISTRATION OF EVENTS AND THE MODES OF THE PSA
OPERATION
PSA is intended for the search of the EM signals considered as the “event”
in the data stream from the sensors - those interesting from the point of
view of scientific tasks of “Chibis-M”. The determination of “event” is
accomplished by the integrated program module of PSA. In the case of EM
“event” recognition it is recorded in one of the memory blocks depending on
the type of event. In addition to this, the waveform which contains the
“event” remains stored in the memory of instrument with the programmed
duration and then it is sent into telemetry system. The PSA software can
operate in several modes. The changes of operation modes and possible
reprogramming of PSA is achieved by the telecommands determined by the
number of selected problems.
