    LocationHarwell, Didcot
    CountryUnited Kingdom
    EducationGraduate
    Contract typePermanent
    Start datewithin 2 months
    Job Description

    Responsibilities

    • Lead Guidance Navigation and Control systems development and design activities for Astroscale missions: derive and maintain AOCS (Attitude & Orbit Control of the System)/GNC (guidance, navigation, and control) sub-system requirements, define and maintain AOCS/GNC sub-system design.

    • Contribute to system level activities, such as: developing mission CONOPS (Concept of Operations), defining FMECA (Failure Mode, Effects, and Criticality Analysis) and FDIR (Fault/Failure Detection, Isolation, and Recovery) processes and design, system test and verification activities.

    • Support control law and algorithms development – analyse, design, implement and validate (simulate) scenarios for RPO (rendezvous and proximity operations), working with flight dynamics engineers to develop passively safe trajectories for RPO. Design control laws to implement RPO & docking manoeuvres.

    • Support development of GNC hardware architecture, trade-off analysis of hardware towards an overall GNC hardware solution.

    • Support development of GNC software architecture, implementing algorithms into GNC flight software, towards an overall GNC software solution.

    • Support procurement engineers with trade-off and selection of GNC equipment.

    • Review and mentoring of AOCS/GNC activities and implementations, providing expert technical feedback, supporting internal review for our projects and providing guidance and mentoring to junior staff.

     

    Essential Skills

    • 3+ years of experience as an AOCS or GNC systems engineer involved in the design, implementation and testing of GNC solutions for actual spacecraft missions.

    • Experience of algorithm & control law development: use of GNC design and simulation software e.g., MATLAB, implementation of control laws and real world effects (non-linearities, signal noise, tuning), translating algorithms into operational flight software. Preferable to have experience of implementation of RPO and docking algorithms and solutions.

    • Experience of hardware trade-offs and hardware and software GNC architectural design.

     

    Desired Skills

    • 5+ years of experience as an AOCS or GNC systems engineer involved in the design, implementation and testing of GNC solutions for actual spacecraft missions.

    • Operational experience of on-orbit satellite operations.

    • Extended experience in control law design, beyond classical techniques: non linear design, optimal.  Any experience of self-learning algorithms (prediction, self-tuning) and AI (Artificial Intelligence e.g. supervised and unsupervised machine learning). 

    • Extensive knowledge of GNC sensor systems (trade-offs/ procurement, data processing) including cameras, IR and LiDAR. 

    • Understanding of safety across the GNC design spectrum: passively safe trajectories, safety critical flight software, operator and ground segment interaction (and level of autonomy), abort manoeuvres, and collision avoidance manoeuvres.

    • Knowledge of orbital debris removal including licensing, export, regulation, space law.

    • Knowledge of missions concerning active debris removal or RPO: RemoveDebris, CleanSpace / ESA projects e.g. e.DeOrbit, DEOS, ATV, ETS-7, DARPA Express.

     

    Location
