We are looking for a degree educated Engineer to support our customer (ESOC) in the aspects of Flight Dynamics operations for:

–             ENVISAT Orbit Operations

–             GOCE Routine Operations

–             SENTINELS Development

–             SWARM Development.

Required Start Date

1. January 2012




Submission Deadline




ESOC, Darmstadt


Technical Requirements

– In-depth familiarity with applied mathematics, especially vector/matrix algebra, and numerical integration techniques

– Sound knowledge of physics, especially mechanics

– Familiarity with Flight Dynamics operations (operational experience) with emphasis on orbital dynamics

– Prior experience with production of Flight Dynamics documentation and software systems.

– High sense of operational responsibility

– experience with UNIX, FORTRAN 77/95, Matlab or Mathematica

– Familiarity with Sun/Solaris and previous FD operational experience, especially Low Earth Orbit operations, are definite assets

Academic Requirements

A university degree in mathematics, physics, engineering or equivalent with high grades.

Specific Requirements

You must be able to conduct all activities in an orderly and disciplined manner, shall be able to work calmly and correctly under stress and must be able to work with the minimum of supervision.

The working language for the activities covered by this post is English and therefore the Contractor must be able to work effectively in this language and have knowledge of the other.


Background information


Provide routine operations support within the orbit subsystem for the Earth observation mission Envisat and Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) missions.

Orbit determination and control for Goce and Envisat are supported by the NAPEOS infrastructure. The automated routine operations require manual intervention for orbit maintenance and special requests.

ESA is developing five new missions called Sentinels specifically for the operational needs of the GMES (Global Monitoring for Environment and Security) programme.  The Sentinel missions are based on a constellation of two satellites to fulfil revisit and coverage requirements, providing robust datasets for GMES Services. Currently 5 families of earth observation satellites (the “sentinels”) have been identified and the corresponding high-level mission requirements documents have been issued. Each family (e.g. Sentinel-1) shall consist of two satellites launched at about one year apart and operated in tandem for typically 7 years. The orbits are sun synchronous near circular with an altitude and local time of ascending node optimized for the particular mission.

 The objective of the Swarm mission is to provide the best ever survey of the geomagnetic field and its temporal evolution, and gain new insights into improving our knowledge of the Earth’s interior and climate. The Swarm concept consists of a constellation of three satellites in three different polar orbits between 400 and 550 km altitude.
