Drawing on the mission and system requirements outlined in the EROSS+ project, the EROSS IOD project has crafted the initial design for a demonstration mission set for launch by 2027. This mission is planned to be both cost-effective and innovative in its approach.
The mission is designed to demonstrate various in-orbit operations such as rendezvous, fly-around, and the capture of a Client satellite under both prepared and unprepared conditions, as well as robotic manipulations involving the transfer of payloads between spacecraft. It will feature one Servicer satellite equipped with all necessary technologies for these operations, alongside a Dummy Client satellite (standing as a typical orbiting client), equipped minimally to simulate future satellites prepared for these services.
A detailed mission scenario has been developed, specifying the functions and operations required. These encompass the emerging technologies as well as traditional spacecraft components, from power supply to structural elements. The key goal for this year has been to validate the feasibility of the entire mission, culminating in a Preliminary Design Review. This review is crucial as it builds confidence in the mission’s viability and prepares the ground for eventual execution.
Concurrently, there has been a focus on advancing the technologies critical to the mission’s success. This includes the development of the robotic subsystem, which involves autonomous on-board algorithms, software, and hardware components such as robotic arms, and USB-like and refuelling interfaces. The rendezvous technology, too, has seen enhancements with the integration of cameras and lidars, as well as improvements in image processing, guidance, navigation and control systems.
To streamline the development process, a continuous integration approach has been adopted. This method integrates all functions into the targeted payload computer early in the development cycle, allowing for immediate quality checks.
This year’s efforts have enabled all partners to make significant progress in refining their technologies and preparing for preliminary design reviews at the level of each subsystem, setting a solid foundation for the future stages of the project.
