Observation of Light Curves of Space Objects Hirohisa Kurosaki Japan
Observation of Light Curves of Space Objects Hirohisa Kurosaki Japan Aerospace Exploration Agency Toshifumi Yanagisawa Japan Aerospace Exploration Agency Atsushi Nakajima Japan Aerospace Exploration Agency Abstract Geostationary orbit and low earth orbit have many artificial satellites, and the accidents of these satellites affect every area such as weather forecasts and communications. In the optical observation, the periodical change of the brightness which is caused by the type and the shape of the satellite is seen. In the case of LEO debris, since the movement is fast, it crosses the field of view in several seconds. We used an observation method to get the data of LEO debris. In case of the GEO debris, the rate of motion is slow in comparison with LEO debris. Fixed stars are observed by the same position on the image when the telescope is operated in sidereal tracking mode. Then, space objects are recorded on the image with streaks of light. In this paper, the observation and the detection method of light curve of geostationary orbit debris are discussed. Observing the changes of the operative satellites with some time intervals may help to detect the abnormalities and accidents of them. 1. INTRODUCTION Artificial satellites that have finished their missions and used rockets are called space debris. Most of them are not under any control. The space debris problem must be solved to perform future space development and maintain safety. Many artificial satellites indispensable for human activities circle the earth. If one of these satellites malfunctions, many human activities are impacted. An artificial satellite is monitored to control its trajectory while it is in operation. -

Solid-rocket Among the more than 8700 objects larger than 10 cm in Earth orbits, motors use aluminium as a catalyst (about 15% only about 6% are operational satellites and the remainder is space by mass) and when burning they emit debris. Europe currently has no operational space surveillance aluminium-oxide particles typically 1 to 10 system, but a powerful radar facility for the detection and tracking of microns in size. In addition, centimetre-sized space debris and the imaging of space objects is available in the form objects are formed by metallic aluminium melts, of the 34 m dish radar at the Research Establishment for Applied called ‘slag’. -
Satellite Systems
Chapter 18 REST-OF-WORLD (ROW) SATELLITE SYSTEMS For the longest time, space exploration was an exclusive club comprised of only two members, the United States and the Former Soviet Union. That has now changed due to a number of factors, among the more dominant being economics, advanced and improved technologies and national imperatives. Today, the number of nations with space programs has risen to over 40 and will continue to grow as the costs of spacelift and technology continue to decrease.

Classification of Geosynchronous Objects
esoc European Space Operations Centre Robert-Bosch-Strasse 5 D-64293 Darmstadt Germany T +49 (0)6151 900 www.esa.int CLASSIFICATION OF GEOSYNCHRONOUS OBJECTS Produced with the DISCOS Database Prepared by ESA’s Space Debris Office Reference GEN-DB-LOG-00211-OPS-GR Issue 20 Revision 0 Date of Issue 28 May 2018 Status Issued Document Type Technical Note Distribution ESA UNCLASSIFIED - Limited Distribution European Space Agency Agence spatiale europeenne´ Abstract This is a status report on geosynchronous objects as of 1 January 2018. Based on orbital data in ESA’s DISCOS database and on orbital data provided by KIAM the situation near the geostationary ring is analysed. From 1523 objects for which orbital data are available (of which 0 are outdated, i.e. the last available state dates back to 180 or more days before the reference date), 519 are actively controlled, 795 are drifting above, below or through GEO, 189 are in a libration orbit and 19 are in a highly inclined orbit. For 1 object the status could not be determined. Furthermore, there are 59 uncontrolled objects without orbital data (of which 54 have not been cata- logued). Thus the total number of known objects in the geostationary region is 1582.
