Bangkok: Thailand has made a significant stride in space technology with the development of THEOS-3, a new resource exploration satellite that showcases the country's engineering prowess and commitment to sustainable self-reliance. The satellite, a product of the Thai-made research initiative, symbolizes the advancement of Thai engineering and the successful transfer of internationally recognized knowledge.
According to Thai News Agency, the development of THEOS-3 originated from the architectural design and core blueprints of THEOS-2A, a collaborative project between the Geo-Informatics and Space Technology Development Agency (GISTDA) and SSTL from the UK. Thai engineers utilized the flight software and core control system from THEOS-2A as a foundation, further refining them to emphasize system flexibility. The satellite's design allows for modifications in mission equipment and cameras for future missions. A key advancement is the power system, which now permits solar panels to deploy on both sides, enhancing charging efficiency and extending the satellite's lifespan.
THEOS-3's camera capabilities have been tailored to meet Thailand's spatial needs. The satellite features four medium-resolution cameras, increasing the swath width to approximately 20 kilometers. This adjustment is aimed at supporting broad-scale national applications, such as agricultural surveying, flood management, and disaster surveillance. The satellite will enable agencies to monitor disaster situations in real-time, reducing the revisit time for imaging the same area to just one day.
A crucial element of the project is its focus on "domestically produced" components, aimed at strengthening Thailand's space technology supply chain. Initially targeting 10% domestically produced parts, Thai engineers have achieved over 20%. Key components like the aluminum structure, solar panels, and some electronic circuits are manufactured by Thai companies. These components undergo stringent quality control by GISTDA engineers to ensure they withstand extreme space conditions. With a budget of approximately 300-400 million baht, the investment focuses on research, development, and system integration, promising to reduce future satellite production costs.
The project is currently in its mid-stage, with engineering simulation equipment being delivered for testing. In the coming months, a major review meeting will initiate the assembly and system testing process for the actual model, set for space deployment next year. The launch of THEOS-3 is a testament to Thailand's readiness to emerge as a developer of space technology.
