The new project will develop robotic satellite technologies to reliably connect with other satellites to perform in-orbit repairs and maintenance. It will be led by the University of Sydney and is supported by SmartSat CRC and NSW-based industry partners Abyss Solutions, ANT61, Space Machines Company, Sperospace and Spiral Blue.
Servicing satellites in orbit is challenging due to harsh space conditions, potential risk of damaging expensive assets through collision during docking, and difficulties maintaining stability during maintenance.
Leading the project is Dr Xiaofeng Wu, Senior Lecturer in Space Engineering in the School of Aerospace, Mechanical and Mechatronic Engineering. He said developing foundational Australian ISAM capabilities will help meet Australia鈥檚 future sovereign needs and equip local companies with advanced technologies, providing them with advantages in the global ISAM and broader space industry.
鈥淎ustralia needs to start laying the groundwork now to compete in this vital and emerging $US14.3 billion market. The University of Sydney is ideally positioned to play a leading role in establishing the country鈥檚 first integrated set of core capabilities for autonomous orbital robotics. This core capability set will enable Australian industry to undertake advanced, fit-for-purpose, autonomous robotic satellite missions to meet commercial, civil and defence needs," Dr Wu said.
SmartSat CRC Chief Executive Officer Professor Andy Koronios said research into ISAM technologies is critical for Australia to help our local industry join the emerging global supply chain in this increasingly important field.
鈥淲ith the number of satellites and spacecraft in orbit increasing rapidly, there鈥檚 a greater likelihood of malfunctions and collisions. Being able to service and upgrade satellites in-situ, thereby extending their lifespans, will be a crucial capability for governments and the private sector alike,鈥� Professor Koronios said
This project brings together four technology areas into one research project, ensuring an end-to-end approach to address complex challenges facing in-orbit repair and satellite maintenance.聽

The ISAM project will address:
- High-level, AI-driven onboard automation for mission operations, ensuring real-time performance in harsh space conditions.
- Advanced sensing to detect far-away objects and aid navigation in challenging lighting
- Fault-tolerant navigation systems for accurate detection and tracking in a variety of space environments聽 and small objects, while using limited hardware and computational resources.
- Safe control strategy to stabilise the servicing satellite while the robotic manipulator is in operation, avoiding damage to spacecraft
The project's aim is to build end-to-end software technology聽and demonstrate it on the ground, with the aim of deploying it on future satellites.
DECLARATION
The University will receive $1.05million from SmartSat. The remaining amount is an in-kind contribution from the University of Sydney and the project鈥檚 industry partners, which will work with the University to integrate their technologies and demonstrate the feasibility of a future all-Australian satellite servicing mission. 聽
