Definition

The total velocity increment consumed by a station-keeping strategy over one year, typically measured in m/s. It is the primary metric for evaluating the cost-effectiveness of different orbit types and station-keeping strategies. This study finds that large-amplitude DROs have the lowest annual cost, while NRHOs generally have the highest.
