Abstract
The recent increase in small satellites and diverse satellite missions has heightened the need for flexible and highly reliable ground station software. However, most existing open-source ground station software is implemented with the entire system in mind, making it difficult to accommodate diverse missions. Even when accommodating diverse missions, it is necessary to edit configuration files with a wide range of descriptions or make internal service modifications. Furthermore, as the number of available ground station services increases, there is an urgent need for systems that can support a wider range of interfaces. In addition, modern satellite development requires flexible support for diverse use cases, such as ground testing, software-in-the-loop simulation (SILS), and hardware-in-the-loop simulation (HILS). To address these needs, the proposed system THESEUS (Telemetry Handling & Extensible Satellite Environment for a Unified System) is highly modularized, with functions such as database logs and user interfaces divided into small, independent components. The proposed THESEUS system adopts a highly modularized design that divides functions such as database logs and user interfaces into small independent components. This design allows for easy reconfiguration in response to changing requirements from the development stage to the operational stage (ground testing, SILS, HILS, and production operations). In this presentation, we will introduce open-source ground station operation software that has been redesigned from a system already in use at our laboratory. This system adopts a scalable, distributed architecture that automatically establishes connections with available ground stations based on satellite orbit information and can switch operations as needed. Furthermore, a versatile API and cache server enable flexible changes to operational sequences. Furthermore, the distributed architecture, in which each component is independent yet interconnected, makes it easy to reconfigure modules according to operational requirements. For example, new data logging and convenience features can be developed as independent modules and seamlessly integrated into the overall system. This system has been applied to the operation of the ONGLAISAT satellite and has achieved good results in terms of both real-time performance and stability. Compared to conventional monolithic systems, the addition of new functions is simplified, secure connections with multiple ground stations are guaranteed, and rapid adaptation to operational scenarios involving different ground station facilities is possible. With its excellent scalability, the system can be seamlessly utilized in SILS, ground testing, in-orbit operation, and HILS phases. This paper discusses the main design and implementation points of the system, the results obtained from in-orbit operation, and prospects for future improvements.
