Guidance, Navigation and Control Engineer
Craft reliable flight control systems for astronomical research platforms.
What is a Guidance, Navigation and Control Engineer?
GNC engineers in astronomy develop and implement control algorithms for telescopes, satellites, and other space-based instruments. Their work ensures precise pointing, tracking, and stabilization, enabling accurate data collection. They work with sensors, actuators, and embedded systems to achieve optimal performance.
You spend most days indoors in labs and offices choosing sensors, drafting mechanical design documents, and developing control hardware and software. Work alternates between writing specifications, running qualification or hardware-in-the-loop tests, and coordinating with contractors and team members via email and meetings. Attention to detail drives tasks from component selection through documentation and integration.
The hats you wear
The Algorithm Architect
Designs and develops novel control algorithms to meet specific performance requirements, ensuring stability and accuracy of the system. Often involves mathematical modeling and simulation.
