The latest space debris related research and technology activities in the European Space Agency

第6回スペースデブリワークショップ (2014年12月17日-19日. 宇宙航空研究開発機構調布航空宇宙センター(JAXA)(CAC)), 調布市, 東京

6th Space Debris Workshop (December 17-19, 2014. Chofu Aerospace Center, Japan Aerospace Exploration Agency (JAXA)(CAC)), Chofu, Tokyo, Japan

This talk will address ESA's progress in space debris research and technology in 4 domains:

1. ESA operates a conjunction analysis system and currently monitors 10 satellites. The system uses the JSpOC CDM data. A number of novel techniques have been developed including automation in the processing of the data, new algorithms for low delta-v approaches and independent manoeuvre screening. ESA's conjunction assessment system and related statistics and highlights will be presented.

2. Since many years, ESA develops object databases, as well as risk assessment and mitigation analysis software. Methods for the verification of the compliance to on-ground risk and orbital lifetime assessment have been developed. ESA, as an operator of objects in very unusual orbits such as high-eccentric and Lagrange Point orbits has developed novel disposal options which have been validated with these new means. The means and related technology will be presented along with recent examples.

3. Further, ESA runs an ambitious SSA program, for which a system architecture has been designed and a demonstrator phased-array radar has been developed. In addition to this, it operates its own 1m-telescope on Tenerife which has discovered a population of high area/mass objects. Recent radar and optical as well as laser ranging measurements concentrate on the identification of the attitude motion of uncontrolled objects, like Envisat. An overview over the current measurement systems and recent results will be presented.

4. Finally, ESA has been investing in the technology for rendez-vous and capture of uncontrolled objects. Various solutions have been scrutinized in system studies. In parallel, the effect of active removal and the criticality of a given objects in LEO orbit has been studied. This presentation will show ESA's analysis results and the recent plans for the e.Deorbit mission for the controlled removal of an uncontrolled target in LEO.
