Where 'near GEO' mentions orbits that may interact with objects in GEO, for example Geosynchronous Transfer Orbit (GTO) and a little higher storage orbit for abandoned satellites. Less information is on hand about the space debris environment in and near GEO than in Low Earth Orbit (LEO), especially about micro debris. Because GEO is much farther from the ground than LEO, it is possible to detect only large objects near GEO from the ground based observatory, and catalogued objects in there are larger than approximately 1 m in diameter. There should be great number of unobservable micro debris in and near GEO. They will be fragments from break-up of spacecrafts, exhaust particles from solid apogee kick motor or natural meteoroids. In fact, two break-ups in or near GEO have been confirmed, that is CIS Ekran 2 in 1978 and US Titan 3C Transtage in 1992. An onboard surface inspection system to detect micro space debris impact in and near Geosynchronous Earth Orbit (GEO) is proposed in this paper. This system consists of a small camera, data handling and communication subsystem. It will be mounted on some geosynchronous satellite, and survey on surfaces of the mother satellite. When it may detect an image of crater on the surface damaged by the micro space debris, the image should be transmitted to ground for further analysis. Then it will be possible to determine physical properties of the debris impacted, i.e. size, mass and impact velocity. This type of observer will be useful to measure flux of so small debris in so high orbit, that it is impossible to detect them from ground-based facilities nor retrieve impacted samples from there.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
