Summary
The KODEN is a first in-orbit laser communication demonstration between a low earth orbit satellite called OICETS/Kirari and an optical ground station at the National Institute of Information and Communications Technology (NICT) in Koganei, Tokyo. Optical links could always be established even under atmospheric turbulence when partly clear skies were predominant in March, May, and September, 2006. The uplink and downlink bit error ratios were measured to be 10−7–10−3. This achievement is a milestone for future high-data-rate satellite communications.
Zusammenfassung
Das Akronym KODEN steht für die erste erfolgreiche Demonstration eines Laserkommunikationsexperiments zwischen dem Satelliten OICETS/Kirari in erdnaher Umlaufbahn (LEO) und der optischen Bodenstation des staatlichen Institutes für Information und Kommunikation (NICT) in Koganei, Tokio. Trotz atmosphärischer Turbulenzen konnte die optische Verbindung stets hergestellt werden, unter vorwiegend wolkenfreiem Himmel in den Monaten März, Mai und September 2006. Die Fehlerbitraten der beiden Kommunikationskanäle lag zwischen 10−7–10−3. Das Experiment stellt einen Meilenstein in der Entwicklung zukünftiger Satellitenkommunikationssyteme mit hohen Datenraten dar.
