“…If it is reduced to half, objects four times darker can be detected. The typical seeing size at BSGC is about 2 arcsec, 14) whereas that at YO was 5.7 arcsec when we observed the GEO object. As a result, the BSGC system can detect objects (5.7/2) × (5.7/2) times darker than the YO system can.…”

In this paper we propose a new method known as "the stacking method" to detect small pieces of unknown GEO debris, in which several images taken with a CCD camera are used to detect this debris. With this method, the streaks of stars are completely eliminated, and the sky background fluctuation decreases significantly. This allows the detection of very dark debris that is not visible on a single image. We tested this method by using the 45 cm telescope at the Yatsugatake Observatory and a small CCD camera manufactured by Nakanishi Image Laboratory (N.I.L). The globular cluster M13 was observed to evaluate the method and to calculate the limiting magnitude. The three regions of the geostationary orbit were also observed to search for unknown GEO debris. One possible piece of GEO debris about 1 m big was detected as a result of analysis that used the stacking method. The limiting magnitude shows that we can detect GEO debris of about 50 cm in size. With this method, by means of observation using the facilities at the Bisei Spaceguard Center (BSGC), a 1 m telescope, and an SITe CCD camera, we may be expected to detect GEO debris of about 10 cm in size.

This paper proposes a new method known as ''the line detection method'' to detect small pieces of low Earth orbit (LEO) debris. A direction is assumed for the line created by small LEO debris on a CCD image and the values of pixels along that direction are accumulated to improve the signal-to-noise ratio. This method can detect LEO debris that is 30 to 40 times darker than debris that can be detected by usual methods. We tested this method by using the 35-cm telescope and back-illuminated CCD camera at the Mt. Nyukasa Astronomical Observatory. One small piece of LEO debris with a radar cross section of 0.0047 m 2 was detected. By using this method, the 1-m telescope and back-illuminated wide-field camera at the Bisei Spaceguard Center (BSGC) are expected to be able to detect LEO debris with a size of a few cm. The line detection method will be used to probe the LEO small debris environment and contribute to solving the space debris problem.

“…Vice versa, the NEAT system in Maui has been successfully used to survey high-altitude artificial objects in space (Africano et al 2001). One system, the Bisei Space Guard Center (BSGC), consisting of 0.5 and 1-m telescope has been conceived as combined NEO and space debris survey system already from the beginning (Isobe et al 2004(Isobe et al , 2000. A comprehensive review on the NEO programs may be found in Stokes and Evans (2002).…”

Space debris-man-made non-functional objects of all sizes in near-Earth space-has been recognized as an increasing threat for current and future space operations. The debris population in near-Earth space has therefore been extensively studied during the last decade. Information on objects at altitudes higher than about 2,000 km is, however, still comparatively sparse. Debris in this region is best detected by surveys utilizing optical telescopes. Moreover, the instruments and the applied observation techniques, as well as the processing methods, have many similarities with those used in optical surveys for 'astronomical' objects like near-Earth objects (NEOs).The present article gives a general introduction to the problem of space debris, presents the used observation and processing techniques emphasizing the similarities and differences compared to optical surveys for NEOs, and reviews the results from optical surveys for space debris in high-altitude Earth orbits. Predictions on the influence of space debris on the future of space research and space astronomy in particular are reported as well.
