Description of the job

Airbus Defence and Space (Toulouse) is looking for an intern for a 6 month internship.

Agile satellites performing quick line-of-sight reorientation generally make use of open loop commands. This concept allows quick reorientations while keeping a reasonable control bandwidth. The open loop computation is based on an estimate of the system dynamics. Hence the open loop efficiency relies on a good knowledge of the system dynamics.

Recent R&D studies have explored new concepts of combined inertia and actuator alignment estimation. Preliminary simulations tend to show a real enhancement of estimation performance with respect to current in-flight calibration concepts. These concepts, based on Kalman filtering theory, make use of sensors and actuators telemetries to estimate the satellite inertia and the actuator alignments.

This internship will start on 3 rd April 2017 (subject to some flexibility).

Profil recherché

Tasks & accountabilities

The objective of the internship is to test the new estimation concept on real flight data to consolidate the performance and the tuning of the algorithms.

You shall handle the telemetry data and convert them in the suitable format; then the data will be fed to the MATLAB/Simulink prototype of the estimation algorithm.

After defining some evaluation criterion of the estimates, the performance of the filter will be assessed and updates/optimization of the concept will be investigated.

Required skills

You are in the 2nd year of a master's or the 5th year of engineering school, university or equivalent specializing in Aerospace Engineering.

You ideally have an initial experience in this domain.

You have knowledge of:

·  Filtering and estimation
·  Space dynamics
·  Matlab / Simulink.

You are a strong team player and have excellent interpersonal skills.
