Delta-V assisted periodic orbits around small bodies

Delta-V assisted periodic orbits are introduced as a new type of periodic orbit around small bodies subject to strong solar radiation pressure. Delta-V assisted periodic orbits are made periodic by introducing a small deterministic delta-V within each period. This type of orbit has a simpler shape and provides higher flexibility than other periodic orbits and therefore enables missions with higher scientific value. The general theory of delta-V assisted periodic orbits is described, including the orbit design methodology, solution-space analysis, and stability analysis. This paper clarifies that delta-V assisted periodic orbits are useful and feasible options for small-body missions and exhibit unique dynamic characteristics.
