Master student / Internship (m/f/d) in Information Technology or Physics

German Aerospace Center (DLR); Oberpfaffenhofen; Vor Ort; EUR 70.000 - 90.000; Vollzeit

Zusammenfassung

The DLR Institute of Communications and Navigation is seeking a skilled software engineer to implement real time approaches for adaptive optics software. You will define real-time requirements, evaluate Ubuntu PREEMPT_RT, and optimize inter-component communication between camera, wavefront processing, controller, and deformable mirror.

Applicants should have hands-on experience with C++, Linux, Python, Git, Docker, and real-time systems, and be motivated to join a mission-oriented research

Qualifikationen

• Experience developing real-time software for adaptive optics preferred.
• Proficiency with C++, Linux environments, and Python.
• Experience with Docker containers and containerization.
• Familiarity with version control (Git) and build systems (CMake).

Aufgaben

• Define the real-time requirements of the adaptive optics control loop.
• Evaluate Linux-based real-time solutions (e.g. Ubuntu with PREEMPT_RT).
• Introduce real-time thread scheduling, priorities and CPU affinity.
• Evaluate memory locking and preallocation to avoid delays.
• Optimize communication between camera, wavefront-processing, controller and deformable-mirror components.
• Investigate network/middleware impact on control-loop timing.
• Develop reproducible configuration and deployment procedures for the real-time system.

Jobbeschreibung

The DLR Institute of Communications and Navigation is dedicated to mission-oriented research in selected areas of communications and navigation. Its work ranges from the theoretical foundations to the demonstration of new procedures and systems in a real environment and is embedded in DLR's Space, Aeronautics, Transport, Security and Digitalization programmes.

What To Expect

Optical free space communications are an exciting technology under intense development to provide secure high bandwidth communications to all areas of the world. In order to provide reliable light reception at the Optical Ground Station, Adaptive Optics is used to sense wave-front aberrations in the light and correct it in real-time. This requires high optical precision, high performance control systems and accurate calibration procedures.

Your tasks

In this role, you will be responsible for implementing suitable real time approaches to our adaptive optics software.

Your Duties Will Include

• Defining the real-time requirements of the adaptive optics control loop
• Evaluating suitable solutions. E.g. Linux-based real-time solutions, such as Ubuntu with the PREEMPT_RT real-time kernel
• Introducing real-time thread scheduling, thread priorities and CPU affinity
• Evaluating memory locking, preallocation and other techniques for avoiding unpredictable delays
• Optimising communication between the camera, wavefront-processing, controller and deformable-mirror components
• Investigating the influence of network and middleware communication on control-loop timing
• Developing a reproducible configuration and deployment procedure for the real-time system

Your profile

Familiarity With Some Of The Following Is Desirable

• C++,
• Git
• CMake
• Linux Environment
• Python
• Docker containers
• Real time systems

We look forward to getting to know you!
