System level studies to design optical surveillance networks in the frame of the EUSST Support Framework

摘要

The "Decision of the European Parliament and the Council Establishing a Space Surveillance and Tracking Support Framework" [1] was adopted on April 16th 2014. It has established the SST Support Framework with the objective of ensuring the long-term availability of European and national space infrastructure, facilities and services through the establishment of an SST capability at European level and with an appropriate level of European autonomy. The specific objectives of the SST Support Framework are: ? to assess and reduce the risk to in-orbit operations of European spacecraft from collisions, ? to reduce the risks related to the launch of European spacecraft, ? to survey uncontrolled re-entries of space objects into the Earth's atmosphere ? to seek the prevention of proliferation of space debris.
