Aspect Dependence and Frequency Spectrum of Electrical Discharges on the P78-2(SCATHA) Satellite.

Abstract

The SCATHA (P78-2) satellite payload includes a Charging Electrical Effects Analyzer to measure the characteristics of electrical discharges that occur on the vehicle due to spacecraft charging. During 233 days of operation, 19 pulses on 10 different days have been related to electrical discharges. Five of these discharges took place when the pulse analyzer was in a mode with sufficient time resolution to resolve the frequency components in the waveform. The dominant frequencies ranged from 5 to 32 MHz with amplitudes from 0.4 to 0.9 V into a 50-ohm load. (Author)
