System impacts of propulsion Passivation

Space debris mitigation requirements specific to propulsion systems are scrutinized and compliance of OHB reference propulsion architectures is assessed. The risk of generating debris due to a failure in a propulsion system is assessed with a focus on the specific risk of a hypervelocity impact on a propulsion tank containing residuals.

The engineering activities, delta-qualifications or hardware development which can support the recommended propulsion passivation strategies are presented and prioritized.

Automatic Spacecraft Status Characterisation By Data Mining Mission History

The main purpose of this project, as mentioned in the SoW, was to analyse historical mission data and search for new features which would be useful in the telemetry checking, command verification and procedure writing process in the future.
Features of a signal (or parameter in this context) are defined as characteristics that can be measured or calculated over a given time window (such as mean, standard deviation or minimum of a signal).

Concept Definition and Demonstration of RAMS In-Orbit Data Utilisation

RAMS and risk assessments performed in the course of the system design, verification and operation of space systems rely on the availability of realistic input data. This input data is coming mainly from three different sources:
- MIL-HDBK-217F, Notice 2 for EEE components
- manufacturer supplied information (e.g. pyrovalves, reaction wheels)
- expert judgement based on experience and on the adaptation of data from space and non-space applications.

Autonomous Planetary Payload Survival Support System (APPS)

The objective of the APPS study has been to investigate the feasibility, architectural and system design, and potential performance of a non-nuclear system whose single goal is to provide survival and servicing support to a planetary payload element, in order to ensure its operations despite the absence of sunlight for extended periods. The principle aim is to advance concepts and overall approaches to meet this goal, and to provide a framework for the future development of key technologies.
