Intern in the Electrical Department - AOCS and Pointing Architecture Section
Noordwijk, NL
Location
ESTEC, Noordwijk, Netherlands
Our team and mission
The Attitude and Orbit Control System (AOCS) & Pointing Architecture Section provides functional support to ESA projects in the technical field of AOCS & pointing systems for ESA missions on the following applicative directorates: Earth Observation, Science, Resilience, Navigation & Connectivity.
The AOCS & Pointing Architecture Section carries out technological research, harmonisation and standardisation in the field of AOCS and Pointing systems, with a focus on subsystem competitiveness, and innovation for performance, robustness and process improvements.
Candidates interested are encouraged to visit the ESA website: http://www.esa.int
Field(s) of activity for the internship
As an intern in the AOCS & Pointing Architecture Section, you will develop an AOCS & pointing performance assessment tool and its time-domain simulator with a robust tuning pipeline to enable early mission feasibility assessment and architecture trade-offs.
The objectives are:
- to model and document the main performance drivers with focus on gyroless architectures and Star Tracker accommodation (including fusion of non-orthogonal Star tracker Optical Heads, dynamic-stellar estimator, and tachometer-stellar estimator);
- to consolidate the controller tuning optimisation (already implemented in the tool) with robust control synthesis & analysis for further optimised performance, with a generic design & tuning pipeline and the documentation of the process (including of the comparison with respect to the initial optimised tuning);
- to consolidate the architecture trade-off capacities (already implemented in the tool) by performing and documenting systematic performance evaluations over sets of Hardware suites (sensors and actuators) for architecture trade-offs, for different missions;
- to consolidate the early micro-vibrations impact assessment (already implemented in the tool) with improved Reaction Wheel disturbance spectrum (waterfall plots catalogue) & high frequency dynamics envelope and the documentation of the models & process (how to set the dynamics envelope without a full satellite Finite Element Model);
- to consolidate the verification & validation of the tool & simulator with built-in verification tests and documentation;
- to consolidate the tool & simulator documentation, with a user manual & hands-on training (setting of the tool, configuration for a new satellite mission, running early performance assessment and performing architecture trade-offs, controller optimised tuning, and running consolidated performance assessment with further improved robust tuning).
This updated version of our tool will be used for early definition of future Earth Observation and Science missions during the internship.
