Electromagnetic Effects & Spacecraft Charging
NASCAP / GEO
Description:
The NASA
Charging Analyzer Program is meant to simulate spacecraft
charging at geosynchronous orbits. NASCAP has been
specifically developed as an engineering tool to determine the
environmental effect on spacecraft surfaces and systems. It
can analyze the surface charging of a 3-D, complex body as a
function of time for given space environmental conditions and
specified surface potentials. Material properties of surfaces
are included in the computations. Surface potentials, low
energy sheath properties, potential distributions in space,
and particle trajectories are computed. By locating severe
surface voltage gradients in a particular design, it is
possible to show where discharges could occur. The effect of
changes in the surface materials or coatings in those areas on
minimizing voltage gradients can then be evaluated.
