ECSS Communications — Short Contact Periods (space-systems/ecss/e50-short-contact-periods)

Size a space link against the contact periods a mission actually gets, under ECSS-E-ST-50C Rev.2 clause 5.6.3. Use when the task is deciding whether short contacts can move the data a spacecraft produces: subtracting link acquisition and setup time from each pass, converting the usable time into a deliverable volume through the coding rate and framing efficiency, walking the schedule so the onboard store fills between passes and drains during them, flagging a pass consumed entirely by its own setup, and reporting overflow and whether the backlog is stable.
