In order to support the technology development and product improvement for future satellite navigation payloads, Airbus Defence and Space is looking for a PhD student in the field of Advanced Navigation Payloads (d/f/m) You are looking for a PhD and want to get to know the work of a job title? Then apply now! We look forward to you supporting us in the Navigation Payload Engineering department (TSEDA8) as a Doktorand (d/f/m)! Location: Taufkirchen Start: As soon as possible Duration: 3 years Your location Our site is just a stone's throw away from Munich, the beautiful capital of Bavaria. Are you into sports and other outdoor activities? The Alps and Lake Starnberg are within an hour’s reach, offering a multitude of recreational options. Your benefits An exciting topic with the potential that your found solutions will become state-of-the-art to be implemented in next generation navigation/telecom satellites. Attractive salary and work-life balance with an 35-hour week (flexitime). International environment with the opportunity to network globally. Work with modern/diversified technologies. At Airbus, we see you as a valuable team member and you are not hired to brew coffee, instead you are in close contact with the interfaces and are part of our weekly team meetings. Opportunity to participate in the Generation Airbus Community to expand your own network. Your tasks and responsibilities Airbus Defence and Space is currently designing and manufacturing the second-generation of Galileo satellites. The digital processed navigation payload with advanced antenna is in charge of generating the GNSS signal with low distortions in order to meet the challenging Signal-In-Space (SiS) performance requirements. This PhD thesis is aiming towards the next batch of G2 payloads with the overall objective to support reducing payload Size, Weight and Power (SWaP), simplifying RF performance requirements towards amplifiers and antenna, improving SiS performance and enhancing on-board autonomous detection of failure and signal impairments. In order to approach those objectives, the PhD thesis tasks may include: Analysis and Improvement of Advanced Navigation Antenna incl Digital Processing Analysis of architectural concepts Definition for an efficient signal processing with particular need for low distortions and robustness to RF chain and Navigation Antenna performance variations Analysis and Improvement of advanced On-Board autonomous signal distortion equalisation techniques Representative modelling, in particular for non-linear, frequency dependent channel characteristics of high-power amplifiers Analysis of concepts and definition of improved equalisation technique for GNSS signals in digital enhanced payload / antenna Improve knowledge of specific performance topics of new G2 signals (e.g. understanding SiS performance for small bandwidth signal) Modelling of navigation signal generator, digital feed, equalisation, RF payload and navigation antenna Development of Matlab-based simulator Validation on hardware Implementation in Hardware, Software and FPGA and Validation Trade-offs for Space Implementation incl functional architecture with space-grade FPGAs Implementation in COTS hardware, FPGA and software Validation with on-ground demonstrator
