GalaxEye is hiring a GNC Lead for DG-2 Nexus, a kg class smallsat. The role carries two mandates: acting as GalaxEye's technical authority over a turnkey ADCS procured from an external vendor, and building our internal ADCS design and analysis capability in parallel. You must be able to independently reproduce and challenge the vendor's analysis rather than manage it at arms length.
Job Type: Full time.
Location: Banglorenorth, Karnataka, India
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 CDH
- 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
Desirable
- Earth observation mission GNC agile, slew-intensive tasking
- Smallsat ADCS in the kg class
- Flexible body dynamics and jitter analysis
- Hardware- or processor-in-the-loop test setup
- Flight software interface algorithm handover and VV
- Orbit determination and GNSS processing
- On-orbit commissioning and anomaly resolution
- Familiarity with the ADCS supplier landscape
Qualifications
- Degree in Aerospace Engineering, Control Systems or a closely related discipline; postgraduate qualification preferred
