Master Thesis: LISA Calibration Procedures & Accuracies

LISA: Laser Interferometry Space Antenna

• ESA Cosmic Vision Mission measuring gravitational waves (e.g. from black holes in space;

• Constellation mission acts as a giant detector based on a Michelson interferometer;

• Most complex control and estimation architecture ever flown in space (60 degrees of freedom);

• Measurement accuracies up 10-15 ms-2 at frequencies of about a millihertz;

• Calibration (=estimation of spacecraft noises sources, such as sensor misalignments, sensor biases, actuator biases, internal gravitational gradients) is driving LISA Performance;

• ESA Study lead by Airbus Friedrichshafen, with a large heritage from LISA Pathfinder;

Tasks

• Support the functional analysis of the LISA constellation;

• Identify the control and estimation loops including the required performance;

• Identify the calibrations procedure and in detail:

 The required accuracies to reach the LISA mission performance;

 The calibration procedures: duration, manoevres, (Kalman) filters to be used;

 The achievable calibration accuracies.

Organisation

• Master thesis (6 months, from Spring 2020 on, starting date free);

• Please send motivation and CV directly to simon.delchambre@airbus.com.
