Job Description

Are you looking for a final year project? Would you like to discover the work of an engineer? Then apply now! We look forward to you joining us. The AOCS, GNC & FD department is in charge of attitude and orbit control systems (AOCS), Guidance/Navigation/Control (GNC), flight dynamics (FD), and control engineering for all kinds of spacecraft. This includes aspects such as modelling, design, synthesis, and verification & validation of the AOCS/GNC system.

Location: Friedrichshafen / Immenstaad

Start: September 2022

Thesis Title

Derivation of Linear Fractional Transformation (LFT)-Based Model with Probabilistic Uncertainties for the Use in Worst Case and Robustness Analysis of the LISA Mission

Thesis Topic

LISA is the first space mission to establish the new field of gravitational wave astronomy, observing highly energetic events within the entire event horizon of the universe. As the instrument is distributed over a constellation of three spacecraft with ultra-high relative measurement precision needs, LISA is among the most ambitious missions ever flown. One of the main challenges for gravitational wave detection is to shield the test masses from external disturbances and to minimize any non-gravitational impact.

Based on the heritage of the precursor mission LISA Pathfinder (LPF) and the equations of motion for a LISA spacecraft, the main objective of the thesis is to derive a model of the multi-body system dynamics based on Linear Fractional Transformation (LFT) using probabilistic uncertainty methods. The model serves as baseline for robustness, sensitivity and worst-case analysis with respect to uncertain parameters affecting stability and performance of the system.

You Will Learn About

The LISA mission, S/C systems engineering, multi-body dynamics and modelling, probabilistic uncertainty modelling, being part of project team in a challenging space mission
