User and Mission Requirements

User and Mission Requirements

The user and mission requirements are derived from a host of national and international standards and regulations.


While the system of international space treaties (e.g. the Outer Space Treaty of 1967) provide rather rough guidelines on space debris, more recently the UN Committee on the Peaceful Uses of Outer Space – particularly the Working Group on the Long-term Sustainability of Outer Space Activities – has drawn up a much more comprehensive and concrete set of guidelines.

Based on the guidelines of the Inter-Agency Space Debris Coordination Committee (IADC) two branches of recommendations and requirements were established. A) the European Code of Conduct for Space Debris Mitigation and B) ISO 24113 and ECSS-U-AS-10C.


The European Code of Conduct for Space Debris Mitigation is a voluntary agreement between European national space agencies and ESA. It shall ensure that no new space debris is generated by future missions and it is mandatory for ESA projects with the requirements on space debris mitigation for ESA projects.

Within Europe, ECSS-U-AS-10C is now the primary source of debris mitigation requirements. ESA updated its Space Debris Mitigation Policy document in 2014 to adopt ECSS-U-AS-10C as its standard for space debris mitigation.


All these requirements influence national standards and reports which have again an influence on the requirements itself.

Debris Guidelines

The TeSeR post-mission-disposal (PMD) module shall be compliant to ECSS and ISO.

Based on the user requirements a list of high-level mission requirements is derived.
