Senior🎓
Top SchoolBret Witt is a Guidance, Navigation & Controls engineer with a decade of experience building robotics and space software, now applying his skills at Astranis while completing an M.S. in Mechanical Engineering at UW–Madison. His background spans hands-on simulation and control work at JPL and university labs, including terramechanics, lunar mobility, state estimation, and risk-aware planning for Mars and Moon missions. Comfortable across ROS/ROS2, reduced-order and Gaussian process models, and real-time simulation stacks, he blends academic rigor with mission-driven engineering. Based in Honolulu, Bret brings a practical curiosity—having tutored math and CS and transitioned from a CS bachelor’s into advanced mechanical systems—which helps him translate complex algorithms into reliable onboard and simulation software.
