The Naval Space Surveillance Center (NAVSPASUR) uses an analytic satellite motion model based on the Brouwer-Lyddane theory to assist in tracking over 6000 objects in orbit around the earth. The satellite motion model is implemented by a Fortran subroutine, PPT2. Due to the increasing number of objects required to be tracked, NAVSPASUR desires a method to reduce the computation time of this satellite motion model. Parallel computing offers one method to achieve this objective. This thesis investigates the parallel computing potential of the MAVSPASUR model using the Intel iPSC/2 hypercube multi-computer. The thesis developed several parallel algorithms for the NAVSPASUR satellite motion model using the various methods of parallelization, applies these algorithms to the hypercube, and reports on each algorithm's potential reduction in computation time. A diskette containing the Fortran software is available upon request from email@example.com.
