title = "Analytic approximation for fixed-angle low-thrust trajectories via linear perturbation theory",
abstract = "This paper presents an analytic perturbation solution to the equations of a spacecraft moving in a single plane under constant, fixed-angle, low-level thrust, and influenced by an inverse-square gravitational field. The solution is derived by using linear perturbation theory, which treats the motion of spacecraft as a linear combination of Keplerian motion and perturbed motion caused by the low thrust. Comparisons with direct numerical integration show relatively low errors and advantages in calculating speed for the approximate solution.",
