Oscar Hsu

Oscar Hsu serves as a WFIRST GN&C Systems Engineer, providing critical technical oversight for the guidance, navigation, and control systems of the Nancy Grace Roman Space Telescope mission. In this role, he acts as a key technical liaison between engineering teams and procurement stakeholders, ensuring that acquisition strategies align with mission-critical performance requirements for spaceflight hardware. His responsibilities include defining technical specifications, evaluating vendor proposals for system integrability, and validating compliance with NASA’s spaceflight standards for attitude determination, sensor fusion, and reaction control subsystems. Hsu’s work directly informs the development of solicitation documents and technical evaluation criteria for complex space-based instrumentation and autonomous control systems. While specific contractor relationships are not publicly detailed, Hsu’s technical domain necessitates collaboration with aerospace primes and specialized subsystem suppliers capable of delivering high-reliability GN&C hardware, including inertial measurement units, star trackers, reaction wheels, and flight software modules. He engages with vendors who demonstrate proven capability in radiation-hardened electronics, precision mechanical assemblies, and closed-loop control algorithm development, often requiring rigorous qualification under MIL-STD-810 and NASA-STD-7001. Hsu’s procurement patterns reflect a strong preference for open competition, with 100% of acquisitions conducted under non-set-aside authorities. There is no current emphasis on 8(a), HUBZone, or SDVOSB set-asides, indicating a focus on technical capability over socioeconomic criteria in this highly specialized domain. His primary NAICS classification is 336419, reflecting deep specialization in guided missile and space vehicle parts and auxiliary equipment manufacturing. He procures mission-critical components including flight-grade sensors, attitude control actuators, and autonomous navigation subsystems, requiring expertise in spacecraft dynamics, digital signal processing, and real-time embedded systems engineering.
