PHS Space undertakes the following tasks within TeSeR:
1) Examine options for the preliminary design and configuration of a multi-purpose concept with respect to two primary functions (shielding during the mission and deorbiting after the mission) and three secondary functions (impact detection during the mission, post-mission collision avoidance of trackable objects, and post-mission sweeping of small debris).
2) Review TeSeR project outputs and identify a set of general design rules for implementing post-mission deorbiting capability in spacecraft with a view to possible ISO standardisation.
