Development of 3D Cell Model for Collision Risk Assessment of Space Assets
With the recent surge in the number of objects in orbit, the collision risk to space assets has grown rapidly. Accurately assessing this risk to support safe operations has therefore become increasingly important. We develop a 3D cell model—a space environment modeling technique for collision assessment—and validate it by comparing our spatial density calculations in low Earth orbit and collision risk results for KITSAT against those produced by MASTER, the 3D grid-cell model developed by European Space Agency (ESA).
