Company presentation

The National Center for Space Studies offers France’s space policy to the public authorities and implements it in 5 major strategic areas: Access to Space, Science, Observation, Telecommunications and Defense. More than ever, the conquest of space is at the heart of the daily life of citizens with key economic and societal benefits.

The 2,450 CNES employees work in 4 centers of excellence: the Toulouse Space Center for the design of orbital systems, that of Guyana for the implementation of European launchers, the Launcher Department in Paris for development launch systems and the Paris Headquarters for the development of space policy.

Presentation of the entity/management/BU

In Toulouse, within the Orbital Systems Department, the “SCAO Mechanism and Equipment” service of the “On-board Techniques” sub-department, collects all the skills relating to space mechanisms and SCAO equipment. It has laboratory resources both for the field of mechanisms and that of SCAO equipment. These means make it possible to carry out a diversified experimental work in the implementation and testing of equipment, it is an asset for the acquisition of skills.The service is involved in supporting projects by taking charge of the development, validation and supply of SCAO mechanisms and equipment. On the other hand, it intervenes during the orbital phases for the monitoring of SCAO mechanisms and equipment. Finally, he is in charge of R&T studies in order to develop and promote new technologies for the future, in his areas of expertise.

The “SCAO Architecture” service of the “Flight Dynamics” sub-direction is in charge of the Attitude and Orbit Control System (SCAO) of orbital vehicles, and of the balloon payload pointing system. In his area of ​​expertise, he contributes to orbital systems projects at all stages of their development, from the design phase to the pre-launch, validation and operational orbit phases. He is preparing the future of his profession through R&T studies which can go as far as demonstration in orbit.

The mission

For each phase of a space mission, the Attitude and Orbit Control Subsystem (SCAO) of a space vehicle is in charge of instant orientation (angles, rotational speeds, angular accelerations ) of the vehicle or of a payload to ensure the performance of the mission. A control loop is made up of sensors, actuators and estimation and control laws.

By joining the “SCAO Mechanisms and Equipments” service, then the “SCAO Architecture” service, you will acquire complete knowledge of satellite attitude control systems, from equipment, attitude sensors and actuators, to complete system including estimation and control algorithms.

You will initially build a database of existing equipment of interest for CNES space missions, with their characteristics (mass, size, performance, etc.). You will then refine the knowledge of the performance of some of them by tests on test benches and / or the development of a dedicated test bench for the characterization of magnetometer.

You will then participate in the design of architectures for attitude and orbit control systems, and algorithms that control the attitude of satellites. You will contribute to the development of simulators and to the validation tests of the performances and the robustness of the envisaged solutions, will analyze the results in order to establish the performance reports (score, stability, etc.). You may participate in flight validation of the behavior of the satellites.

Profile of candidate sought:

  • You are undergoing apprenticeship training in a general engineering school, including courses in filtering or signal processing and automation, electromagnetism, CAD, computer science, electronics.
  • You will use calculation and simulation tools like Matlab / Simulink and a CAD tool.
  • A good level of English will be essential for reading or writing technical documents.
  • You are interested in the space field, love teamwork and know how to take initiatives to fulfill your objectives.
  • Autonomous, dynamic, you have analytical and synthesis capacities.

By joining CNES as an apprentice engineer “satellite control and stabilization”, you will develop the most advanced skills, which will open up professional perspectives in the field of flight dynamics, space operations or the design of space systems.
