Abstract. The plasma-wave experiment ASPI (analysis of
spectra of plasma waves and instabilities) on board the INTERBALL spacecraft is
a combined wave diagnostics experiment. It performs measurements of the DC and
AC magnetic field vector by flux-gate and search-coil sensors, the DC and AC
electric field vector by Langmuir double probes and the plasma current by
Langmuir split probe. Preliminary data analysis shows the low noise levels of
the sensors and the compatibility of new data with the results of previous
missions. During several months of in-orbit operation a rich collection of data
was acquired, examples of which at the magnetopause and plasma sheet are
presented in second part of the paper.
