Some results of GEO space debris observations and orbital determination under experimental operation

The Bisei Spaceguard Center (BSGC) is an optical observation facility for Near Earth Objects (NEO) and space debris with 50cm and 25cm telescopes. It is developed by the Japan Space Forum, and operated by the Japan Spaceguard Association from February 2000. At present, NASDA requests BSGC to observe space debris and has evaluated orbits obtained by a debris orbit determination system using observational data at BSGC. This paper shows some results of orbit determination, the debris identification program and ideas for future observations.
