Abstract
Space Domain Awareness (SDA) capabilities involve monitoring the space physical environment, analyzing potential adversaries and their actions, and gaining insight into adversary intentions and predicting possible responses. SDA assists the military in planning, integrating, executing and evaluating military missions in the space domain. The U.S. Space Force (USSF) identifies SDA as a priority for integrating commercial solutions, and posits it as one of the key technologies that have the profound impacts on future national security. As Chinese and Russian space activities become increasingly complex and threaten the global space domain, the importance of SDA cannot be underestimated. In a time where the space is increasingly weaponized and more gray zone activities are taking place in or through the space domain, SDA is critical in developing strategic counterweight and increasing space resilience. It has become a core issue in the formulation of space policies and strategic plans by many countries.
For Taiwan, in the face of the growing space security threat from the China, SDA is considered a crucial technological capability that Taiwan urgently needs to build to resist Chinese aggression. In addition to its strategic geographical location, Taiwan possesses advantages for developing satellite surveillance and can enhance its SDA data collection by establishing fixed and mobile radar stations. Taiwan also holds a leading position in the global semiconductor industry and, based on its technological advantages in artificial intelligence and big data processing, continues to develop high-speed supercomputers, and therefore possesses the computational power for SDA data analysis. Based on these technological advantages, Taiwan can establish an early warning mechanism through cooperation with democratic allies, which will help develop and strengthen its SDA capabilities, establish an asymmetric space warfare advantage, and respond promptly to space threats from China.
