This paper studies the trajectory characteristics of the spacecraft propelled by a ground-based photonic laser propulsion (PLP) system. An spaceborne PLP system was studied in the past years, but a ground-based PLP system may also helpful in space missions. In this paper, a PLP sytem is assumed to be installed in the surface of a celestial body. The equations of motion of the spacecraft in the body-fixed frame is derived,and the corresponded Jocobi integral is found. Contours of zero-velocity lines are presented and trajectories of example missions will be provided as potential applications in the final paper.
