Abstract The USSpaceCom surveillance groundstation network is currently tracking about 6,620 objects larger than 10 cm (Jul.1992). Almost 85% of these are passing through LEO altitudes below 2,000 km. Based on a discretisation technique, the resulting spatial densities and fluxes are analysed in a 2-D (altitude/latitude) distribution model. Resulting debris fluxes from the catalogue objects are determined for a Space Station Freedom orbit, and for a sun-synchronous orbit of similar altitude. Individual flux contributions from distinct inclination and eccentricity domains are discriminated, and the overall collision risk is extrapolated down to hazardous object diameters of 1 cm.
