  Orbital experiment ARINA on the board of Russian satellite Resurs-DK1
launched in 2006 developed to study charged particle flux (electrons E ~ 3 -
30MeV , protons E ~ 30 - 100MeV ) in near-Earth space, especially high-energy
electron precipitation from the inner radiation belt caused by various
geophysical and solar-magnetospheric phenomena. Precipitated electrons under
certain conditions (energy, LB-coordinate) drifts around the Earth and can be
detected as fast increase in count rate of satellite spectrometer (so called
bursts). High-energy electron bursts can be caused by local geophysical
phenomena (like earthquakes or thunderstorms). Such bursts have distinct
features in their measured energy-time distribution. These features contains
information about initial location of electron precipitation. Several methods
(linear, robust regression) were used previously to find longitudinal distance
between region of precipitation and burst registration location on the board of
satellite. In this report, the new ensemble method was developed, it uses the
combining results from several methods in dependence of burst registration
conditions. Numerical simulation of local particles precipitations based on
well-known equations of relativistic particle movement in Earth magnetosphere.
In experimental data analysis, the results from ARINA experiment for 10 years
was used. Several results based on burst experimental data are shown. Ensemble
method shows better results than any single method alone.
