Young Graduate Trainee for Spacecraft Operations and Propellant Usage (Gaia)

This post is classified F1.

Location

ESOC, Darmstadt, Germany 

Our team and mission

This trainieeship opportunity placement is in the Mission Operations Department’s Astronomy & Fundamental Physics Division, which is tasked with preparing the ground segment and operations teams for the launch and operations of ESA’s science missions in the areas of  astronomy and fundamental physics and later performing the flight operations themselves. Missions assigned to the Division include Gaia, XMM, Integral, Euclid and Plato. This opportunity is within the Flight Control Team of the Gaia mission.

The Gaia mission:

Gaia is a Cornerstone ESA Science mission tasked with detecting and accurately mapping the positions of a billion stars to unprescedented accuracy. It was launched in December 2013 and is planned to be operational for at least seven years in an L2 lissajous orbit, 1.5 million km from Earth. Data is downlinked through daily contact with the ground using an X-band GMSK link with a rate of up to 650Gbits/day. More information on the mission, space and ground segment design can obtained using the following links (http://sci.esa.int/gaia/)

(http://www.esa.int/Our_Activities/Operations/Gaia_operations).

Candidates interested are encouraged to visit the ESA website: http://www.esa.int

Field(s) of activity

The Gaia mission operates in a dynamic and thermal performance envelope beyond that of classic space missions. It has very high stability requirements for temperature, vibration and attitude and as such has allowed the detection of disturbances that would escape notice on other missions (e.g. micro meteoroid impacts detected through attitude disturbances and thermal variations in the structure).

The spacecraft attitude is maintained by a cold gas micro-propulsion system that primarily counteracts the Sun radiation pressure. Micro-propulsion systems are also planned for use on future astronomy missions such as Euclid and Lisa.

The control software for the spacecraft attitude takes as its input rate measurements from the payload instrument and attitude inputs from the star tracker which are used to follow a pre-programmed scan law by applying thrust to the micro-propulsion system. Any discrepancy in the input to the software results in a rotational rate error being calculated by the control software and a counteracting thrust being applied. The main part of the proposed project is to study and acquire knowledge of Gaia’s attitude control system and to identify and quantify all the drivers of propellant usage. The output of this analysis may result in proposals for improvement of operational parameters to reduce propellant usage.

In addition to the above core project, the task will also involve general training on spacecraft operations, ground segment and flight segment onboard systems. You will familiarise yourself with the operational facilities used under the mission and may perform additional tasks related to spacecraft mission operations.
