A significant part of meteor activity is associated with meteor streams. Meteoroid streams are accumulations of meteoroids with nearly identical heliocentric orbits. Relative to Earth all particles of a given meteor stream have nearly the same impact directions and velocities. This paper describes the development and applications of two software tools for investigations of meteoroid streams and their applications to orbiting spacecraft. The new tools allow calculations of the number of impacts from meteoroid streams for user selected mass thresholds and time periods. In a second step the resulting number of penetrations through a shield of given thickness can be predicted. Reference calculations for normal stream flux activities and assumed Leonid-Meteoroid-Storm activities are given. Potential extensions of the tool are discussed.
