NASDA's Optical Inter-Orbit Communications Engineering Test Satellite was to be launched by a J-1 in 1998 to LEO. It will demonstrate laser satellite-to-satellite links and pointing and tracking technology. Launch was delayed since the pad was needed for other launches. Eventually J-1 was cancelled and the satellite was finally launched by a Russian Dnepr in 2005. OICETS was renamed Kirari ('glitter') after launch.
The 8194/8474A laser system will be used to communicate with Artemis. An S-band link will be used to DRTS and the ground.
Size is 0.8 x 1.1 x 2.5m, box + 2 panels 9.4m span. Mass 570 kg. Orbit will be 550 x 610 x 97. Control from Tsukuba.
OICETS carries out a high precision acquisition and tracking experiment with Artemis; the optical inter-orbit comms experiment using LUCE, with Artemis; and evaluation of the optical components and of the vibration environment.
In Dec 2005 it made the first 2-way lasercom signal exchange with Artemis.
The Dnepr final stage carried a capsule with commemorative objects for Turkmenistan.
