MASSIVELY PARALLEL IMPLEMENTATION OF MODIFIED CHEBYSHEV PICARD ITERATION FOR PERTURBED ORBIT PROPAGATION Conference Paper

Future Space Situational Awareness (SSA) sensing capabilities will greatly increase the population of trackable space objects, and consequently, the need for accurate and efficient orbital propagation. The serial formulation of Modified Chebyshev Picard Iteration (MCPI) has proven to be an efficient and accurate method for propagating perturbed orbital motion; its performance is comparable to other state-of-practice numerical integrators. However, one significant advantage of MCPI is that it is well suited to parallelization. Initial efforts to implement MCPI using parallel computation have shown additional speedup.1,2,3,4 This paper details a graphics card based massively parallel implementation of perturbed orbit propagation with MCPI.
