Start: October / November
LISA is the first space mission to establish the new field of gravitational wave astronomy, observing highly energetic eventswithin the entire event horizon of our universe. As the instrument is distributed over a constellation of three spacecraft with ultra high relative measurement precision needs, LISA is among the most ambitions missions ever flown. Nevertheless, developments for ground based observatories, a long mission formulation phase as well as the very successful precursor mission LISA Pathfinder, have pushed this observatory into the range of today's technical capabilities.
The main objective of drag-free attitude control system (DFACS) is to ensure free fall of the test massdes in dedicated degrees of freedom by shielding the test mass from all external disturbances. In LISA, the main concern is the ensitive axis along the line of sight of each telescope. In order to detect the changes in the interferometer arm associated with the passing of a gravitational wave, any non-gravitational disturbances have to be minimized in the frequency band of interest.
Tasks & accountabilities
One of the critical DFACS elements, and also focus of this work, is the gravitational reference sensor (GRS) featuring large-gap electrode housings with caging and release mechanisms as well as electrodes providing electrostatic test mass actuation and sensing capabilities in all six test mass degrees-of-freedom. The main GRS functionalities will be directed through front-end electronics (FEE) boxes, enabling the force and torque actuation capabilities.
The main tasks involve:
· Literature research on the precursor mission LISA Pathfinder and the gravitational reference sensor
· Review LPF flight data release tests and derivation of worst case test mass release conditions
· Analysis of the GRS FEE architecture and functionalities
· Analysis of different (state-of-the-art) actuation methodologies to identify potential alternatives for the well-proven actuation approaches used for LISA Pathfinder
This job requires an awareness of any potential compliance risks and a commitment to act with integrity, as the foundation for the Company’s success, reputation and sustainable growth.
