Definition

The time between two consecutive station-keeping impulses. It is a key design parameter: longer intervals typically reduce annual cost but increase position deviation. Stable or weakly unstable orbits (e.g., DROs, NRHOs) permit much longer intervals than unstable halo orbits.

Application Value

Impulse interval is a key station-keeping design parameter: longer intervals reduce annual propellant cost but increase position deviation. Stable orbits like DROs permit much longer intervals than unstable halo orbits.
