OICETS' communications technology is mostly compatible to the optical ground station which was built by German Aerospace Center (DLR) for communications tests in the ongoing projects CAPANINA (Communications from Aerial Platform Networks) and TerraSAR (Synthetic Aperture Radar)-LCT-IOV. Therefore, DLR and JAXA would like to execute a downlink experiment from OICETS to DLR's optical ground station. Purpose of this experiment was to demonstrate the feasibility of high-speed optical data downlinks from LEO (Low Earth Orbit) (e.g. earth-observation) satellites to simple, inexpensive optical ground terminals for future use. The cooperative project was named as 'the Kirari Optical Downlink to Oberpfaffenhofen (KIODO)'. DLR and JAXA entered into Joint Research Agreement on the date of the last signature, April 28, 2006. The Joint Research Agreement remains effective until December 31, 2006. The first meeting was held on February 14, 2006 at DLR Oberpfaffenhofen, Wessling, Germany. The second meeting was on April 26, 2006 at JAXA Tsukuba Space Center, Japan. In those meetings, the period of experiments was determined from June 7-30, 2006. The KIODO trials were successfully conducted during that period, and the third meeting was held on December 5, and 6, 2006 at DLR Oberpfaffenhofen to discuss the results. This document describes the objectives of KIODO project, introductions of the facilities, experiment scenarios, and interface controls through the section two to the section five. In the section six, the results of feasibility assessments are summarized. The section seven shows the schedule. The experimental conditions and measured data in each trial are given in the section eight. The results are summarized in the section nine and the detailed discussions on some issues are described in the section 10., 資料番号: AA0063468000, レポート番号: JAXA-RM-07-003E}, title = {Report on DLR-JAXA joint experiment: The Kirari Optical Downlink to Oberpfaffenhofen (KIODO)}, year = {2007} }
