        Abstract
        The emission and collection of current from satellites or rockets in the ionosphere is a process which, at equilibrium, requires a balance between inward and outward currents. In most active experiments in the ionosphere and magnetosphere, the emitted current exceeds the integrated thermal current by one or more orders of magnitude. The system response is typically for the emitted current to be limited by processes such as differential charging of insulating surfaces, interactions between an emitted beam and the local plasma, and interactions between the beam and local neutral gas. These cuirrent limiting mechanisms have been illustrated for 20 years in sounding rocket and satellite experiments, which are reviewed here. Detailed presentations of the SCATHA electron and ion gun experiments are used to demonstrate the general range of observed phenomena.

          Ion gun operations at high altitudes 

          Werner, Paul W. (Monterey, California : Naval Postgraduate School, 1988);
          Experiments in charge control were conducted on the P78-2 (SCATHA) satellite as part of a program on spacecraft charging at high altitudes. Experiments with the SCATHA ion gun were monitored by charged particle detectors ...

          Analysis of the effects of ionospheric sampling of reflection points near-path for high-frequency single-site-location direction finding systems 

          Teixeira Filho, Carlos Augusto (Monterey California. Naval Postgraduate School, 1990-12);
          This thesis suggests a method to estimate the current value of an ionospheric parameter. The proposed method is based on the known variability of the observed current values near path and utilizes data derived from ionospheric ...
