Abstract

In 1995 ESA released a β-version of their meteoroid and space debris terrestrial environment reference model (MASTER). On a single CD ROM the MASTER release provides all documentation, data, and executables to perform debris and meteoroid flux analysis for earth orbiting spacecraft on a large range of computer platforms. In its high resolution mode the software can be used for a detailed discrimination of flux contributions from historic on-orbit fragmentation events or from sporadic meteoroids for any target orbit from LEO to GEO altitudes. The MASTER model is based on quasi-deterministic principles with comprehensive orbit propagation theories and volume discretisation techniques to derive spatial densities and velocity distributions in a 3D control volume between LEO and GEO altitudes. Debris flux results are discussed for a sun-synchronous LEO and for a highly eccentric GTO orbit.
