The reports considers the problem of developing the optimum thrust angle programs for two constant mass, constant thrust spacecraft engaged in pursuit and evasion in near-earth orbit. The problem is formulated as a differential game in which the pursuer attempts to minimize the final separation distance while the evader attempts to maximize it. The problem is approached by linearizing the equations of motion about a circular reference orbit at the earths surface. The validity of the linearized equations is verified by comparing a linearized trajectory to six non-linear trajectories. The fixed-time and free-time two point boundary value problems are solved for the linear case.
