L5 Mission Design Targeting Strategy

A numerical method for targeting both the transfer orbit and Trojan orbit around the triangular points in the Sun-Earth system is implemented and then tested with a conic approach. This method generates end-to-end trajectories from a low Earth parking orbit at 200-km altitude and 28.5 ° inclination, using a high fidelity model allowing for injection velocity corrections at the parking orbit. Either the position or velocity at arrival in the Trojan orbit around L5 may be targeted. During the injection velocity correction, we use the classical and hyperbolic elements to target the desired orientation and radius of periapsis.
