□ Development of Space Situational Awareness Technology 'Development of Space Situational Awareness Technology' is a project to develop a comprehensive response system and countermeasures to protect people's safety and space assets from the reentry of space objects and collision between space debris and space assets.
In January 2015, the Korean government announced the Korea Astronomy and Space Science Institute as a "Space Environment Monitoring Agency" based on Article 15 of the Space Development Promotion Act (establishment of the basic plan for space risk, etc.) and Article 15.2 And establishing and implementing the basic plan for space risk and its implementation plan related to the case of the space risk, warning and research and development, and implementing it, so that the state is prepared for the space risk.
This basic plan contains three goals: rapid response to space risk, examples and alarms, ability to monitor and analyze space risks, enhancement of capabilities against space risks, and expansion of base. The Korea Astronomy and Space Science Institute 1) Research and development and planning related to space risk countermeasures technology 2) Establishment and operation of related institutions and civil / government / military joint response system 3)Establishment and operation of international cooperation system for prevention and preparation of space risk . The development of the technology to cope with the space risk is aimed at the development of the optical wide area surveillance system for space object observation, the development of the space surveillance radar system, and the development of the space risk analysis technology.
We also support the establishment and operation of the national space risk response system of the Ministry of the Science Technology & ICT, which is the competent authority against the space risk, and support for the construction of the disaster safety system including the establishment of the space risk response manual.
To cope with the space risk, the space risk subcommittee of UN COPUOS participates in the construction of infrastructure and technology for securing independent space surveillance capability and joint action of space risk through international cooperation is very important.
