Stuart Buchan, PhD

Space systems engineer specialising in spacecraft avionics, embedded software, and AI-enabled onboard compute. At Fugro SpAARC, I build mission-ready flight systems using RISC-V, FPGAs, and C/C++. Previously, at Curtin University’s Binar Space Program, I led flight software development for four satellites launched to low Earth orbit, including Western Australia’s first spacecraft. My work spans flight-proven systems and research in spacecraft autonomy and resilience, with a strong interest in strengthening U.S.–Australian cooperation in the space sector.

Experience

Software Systems Engineer
Fugro SpAARC · Perth, WA

Australia’s remote operations and flight software centre supporting NASA, Intuitive Machines, and the Australian Space Agency.

  • Ported NASA’s core Flight System (cFS) to RISC-V SoCs, enabling low-cost, export-compliant processing options for allied space missions.
  • Led development of a web-based cFS table builder that eliminated manual hex editing and reduced configuration time by 5×, enabling safer spacecraft configuration by non-programmers.
  • Emulated candidate flight computers on FPGAs ahead of hardware delivery to validate compatibility with NASA payloads for Australia’s lunar rover mission and support an on-schedule Preliminary Design Review.
  • Built a CI-ready embedded Linux image with QEMU-based virtualisation to support remote development and early software validation on candidate flight-computer architectures.
  • Supported mission operations for Intuitive Machines’ IM-2 lunar mission, helping deliver Australia’s first in-flight command transmission to the Nova-C lander during cislunar transit and extend continuous U.S.–Australia mission coverage.
  • Co-designed a cloud-based collision avoidance service with NASA, fusing Starling and Starlink ephemeris to automatically flag conjunctions under 10 m and support bilateral space traffic management workflows.
Lead Embedded Software Engineer
Binar Space Program, Curtin University · Perth, WA

Curtin University CubeSat program developing compact spacecraft to grow Australia’s sovereign space capability through missions in low Earth orbit.

  • Led flight software development for four satellites launched to low Earth orbit, including Western Australia’s first satellite, Binar-1.
  • Led and mentored engineers and university students across the Binar-2, 3, and 4 missions, expanding local capability in spaceflight software development and operations.
  • Architected the flight software stack in C/C++, including drivers, board support packages, and hardware abstraction layers, improving reuse, performance, and maintainability across missions.
  • Established a CI/CD pipeline with automated testing and rigorous code review to improve software quality and reliability for flight systems.
  • Presented "Binar Space Program: Mission Two Payloads and Operations Plan" at the 2023 AIAA/USU Small Satellite Conference in the United States.
Engineering Teaching Staff
Curtin University · Perth, WA

Laboratory supervisor for mechatronics courses covering microcontrollers, semi-autonomous robotics, and model-based design.

  • Mentored second-year engineering students in applying theoretical concepts to practical robotics and autonomous systems projects.
  • Designed and delivered hands-on workshops to build practical skills in embedded systems and engineering problem-solving.
  • Developed an alternative software environment during COVID-19 that enabled students to continue coursework remotely on personal laptops when standard lab software was unavailable.
Research Engineer
Desert Fireball Network, Curtin University · Perth, WA

Part of the Global Fireball Observatory, a collaboration studying meteorite falls and fireball events worldwide.

  • Constructed, deployed, and maintained automated fireball observation cameras supporting planetary science data collection across the network.
  • Coordinated setup, calibration, and operation of observation equipment, improving reliability and increasing useful observation time.
Software Engineering Intern
CSIRO Astronomy and Space Science · Perth, WA

CSIRO division responsible for major radio astronomy facilities, including contributions to the Square Kilometre Array.

  • Co-developed a navigation and visualisation platform for monitoring measurement points on the Australian Square Kilometre Array Pathfinder telescopes.
  • Designed and implemented anomaly detection algorithms in Python to improve the efficiency and accuracy of radio telescope data analysis.

Education

Doctor of Philosophy
Curtin University · Perth, WA

Thesis: Pushing the Boundaries of Spacecraft Autonomy and Resilience with a Custom Software Framework and Onboard Digital Twin

  • Identified software errors as a significant contributor to CubeSat mission failures, accounting for approximately 35% of total mission failures.
  • Utilised a "Learning From Incidents" approach to identify recurring factors leading to software failures in historic space missions.
  • Applied reliable software design principles to satellite software development, demonstrated through a case study on Western Australia's first satellite, Binar-1.
  • Developed an onboard digital twin for the Binar CubeSat platform running on a memory-constrained flight computer, demonstrating fault prediction and autonomous fault prevention.
  • Successfully integrated the software framework onto Binar-2, 3, and 4 along with the novel onboard digital twin for in-orbit testing.
Bachelor of Engineering (Honours) in Mechatronic Engineering
Curtin University · Perth, WA — CWA: 81.75%
  • Graduated with First Class Honours.
  • Recognised for academic excellence with five letters of commendation from the Mechanical Engineering Board of Examiners.
