GNC Lead

Responsibilities

• Own ADCS requirements, pointing budgets — accuracy, knowledge, stability, jitter, agility, settling — and their flow-down from mission needs
• Own the ADCS SRD and the ADCS-to-bus ICD
• Run vendor technical evaluation and selection; review and independently verify vendor design data packs, analysis and simulation results
• Define and agree the acceptance test campaign; witness and accept vendor testing
• Own sensor and actuator accommodation — mounting, alignment, FOV, thermal, magnetic cleanliness, EMC
• Build and own GalaxEye's internal closed-loop 6-DOF ADCS simulation, including flexible body dynamics and environmental disturbances
• Design attitude determination and control: sensor fusion and estimation, control laws, mode design and transition logic, FDIR and safe mode
• Size actuators and define momentum management strategy
• Run Monte Carlo campaigns for performance and robustness verification
• Provide mass properties, MOI, CG and alignment constraints to the mechanical team; ADCS processing and telemetry requirements to C&DH
• Interface with the Missions team on manoeuvres and attitude control during burns
• Own GNC content at MCR, PDR, DDR, CDR and FRR; own on-orbit commissioning and ADCS performance characterisation

Requirements

• 7+ years in spacecraft GNC/ADCS
• Has taken at least one ADCS through to flight and on-orbit operation
• Deep attitude dynamics and control fundamentals — able to derive, not only apply
• Has built closed-loop ADCS simulations in MATLAB/Simulink, Python or equivalent
• Attitude estimation — Kalman filtering, sensor fusion, star tracker and gyro integration
• Pointing budget derivation and allocation across error sources
• Actuator sizing and momentum management
• Has specified or accepted an ADCS or comparable subsystem from an external supplier
