Systema-Atomox is a 3D geometrical analysis tool for the computation of atomic oxygen (and other species of the residual atmosphere) fluence and resulting material erosion of an orbiting object outer surfaces. This tool accounts for the 3D geometry, the trajectory and attitude, the surface material properties (e.g. absorptivity, diffuse / specular reflection) and computes the species fluence for the mission lifetime. It is particularly adapted to compute the materials erosion of a spacecraft orbiting in Low Earth Orbit.
An advanced Monte-Carlo ray-tracing technique is applied to compute the flux of atomic oxygen. Its principle is to simulate the atomic oxygen / surfaces interactions with enough particles such that the statistics on the simulated results will reproduce satisfactorily the macroscopic behaviour.
The main characteristics of Atomox are the following:
