The course will be held in attendance in SoSe 2022.
Lehrinhalte
This lecture will provide the scientific, technical and operational background in relation to the sources, surveillance and mitigation of space debris. This covers risk assessment aspects: source and sink terms, particle flux models, aerodynamics and aerothermal aspects during atmospheric re-entry and related on-ground risk assessments; all major aspects of space surveillance: ground-based radar and telescope systems, orbit determination methods (batch least square, Levenberg-Marquardt, Kalmanfilter), residuals, covariances, operational collision avoidance; As well as space debris mitigation aspects: long-term environment projection models, international guidelines, passivation methods, shielding concepts, methods for post mission disposal and verification of measures;
On successful completion of this module, students should be able to:
[list=1]
[*]Name the sources of space debris and describe the human-made particle environment and the consequences of particle impacts;
[*]Analyse and determine the risks to a space mission due the natural and human-made particle environment and limit this this risk by suitable technical measures;
[*]Determine the on-ground risk caused by the atmospheric re-entry of a space object;
[*]Lay-out a space mission according to applicable space debris mitigation guidelines and verify the resulting setup along with international standards;
[*]Perform the main tasks of flight dynamics in operations (orbit determination and manoeuvreplanning) and explain the operational processes in the context of collision avoidance;
[*]Present the main technical aspects of space surveillance, lay-out the required sensor systems and apply the related computational methods;
