Impact of controlled and semi-controlled re-entry on Spacecraft design

There is increased attention being given to safeguarding Earth's orbital environment, as reflected by the number of relevant regulations that are being set forward by national governments and international organisations. Among others, ESA has published a Space Debris Mitigation Policy for Agency Projects (ESA/ADMIN/IPOL(2014)2), supported by the corresponding ESA Space Debris Mitigation Compliance Verification Guidelines (ESSB-HB-U-002).

Autonomous Star Trackers in a Modern Attitude and Orbit Control System

The purpose of the study is to investigate the use of ASTs as sensors in modern AOCS. Relatively recently ASTs have developed into a mature technology offering high-performance autonomous attitude determination in relatively small packages.

The investigations into using ASTs used two different types of mission for reference. A large, high- performance scientific mission XMM, as one, and a typical geostationary telecoms mission as the other. Using baseline specifications for ASTs (AD(2) & AD(3)) the studies were performed with focus upon different aspects including:
