Errata: "Optimal Variable-Thrust Transfer of a Power-Limited Rocket between Neighboring Circular Orbits"

Minimum-fuel tiansfers between neighboiing circulai orbits for low-lmust piopulsion systems ha\e been studied The analysis is based on the simplification that only small deviations fiom an oiiginal circular orbit aie allowed, so that the gravitational terms in the equations of motion may be linearized A completely analytical solution is detei mined, and the lesultant thrust-vector control progiams aie compaied with those obtained pie^iously by Hinz for constant-thrust acceleration
