This role involves designing and optimizing the architecture, algorithms, and integration of sensors and actuators to maintain precise satellite orientation. Key tasks include developing advanced control algorithms, modeling system performance, integrating ADCS hardware, and validating functionality through simulations and testing. Post-launch, the role supports on-orbit operations, including calibration, manoeuvre planning, and troubleshooting to ensure mission success.
Responsibilities
* System Architecture and Design: Lead the development and evolution of the spacecraft ADCS architecture, including the design and integration of sensors, actuators, reaction wheels, magnetoquers and control algorithms to achieve mission requirements.
* Algorithm Development: Design and implement advanced ADCS algorithms to support various pointing modes and attitude control scenarios, ensuring precise control over satellite orientation and stability.
* Simulation and Modeling: Perform detailed sensor and actuator characterization, modeling, and simulation to predict system performance and optimize the design. Develop and utilize satellite simulators for system validation.
* Hardware Integration: Specify, evaluate, and select ADCS components, including reaction wheels, magnetorquers, star trackers, IMUs, and sun sensors. Integrate these components into the spacecraft, ensuring seamless interaction with other subsystems.
* Testing and Validation: Develop and execute hardware-in-the-loop (HIL) tests, ground-based simulations, and in-orbit commissioning to validate ADCS performance. Troubleshoot and resolve issues during the integration and testing phases.
* On-Orbit Operations: Support on-orbit guidance, navigation, and control (GNC) system calibration, commissioning, and operations, including maneuver planning and fault management.
Fundamental Requirements
