Wideband InterNetworking engineering test and Demonstration Satellite
"KIZUNA" (WINDS) Completion of the Critical Operation Phase
The Japan Aerospace Exploration Agency (JAXA) shifted the attitude
control mode of the KIZUNA (WINDS) to the regular control mode and
completed its critical operation phase at 8:35 p.m. on March 1, 2008
(Japan Standard Time, JST [1135 UTC]).
The satellite is in good health.
We will further maneuver the orbit from the drift orbit to the
geostationary orbit (at about 143 degrees east longitude) sometime
around March 14. We will also carry out the initial functional
verification of the onboard equipment for about four months with the
National Institute of Information and Communications Technology
(NICT,) the cooperative development partner.
We would like to express our profound appreciation to all of you who
have supported and cooperated with the launch and tracking operation
of the KIZUNA.
We found an output anomaly in the redundant line of the solar sensor
for the attitude control system during the critical operation phase.
However, this anomaly does not effect the KIZUNA's operations as the
main line is working properly. In addition, we will mainly use the
Earth sensor and the inertial reference unit (or gyro) from now on,
thus the anomaly will not cause a problem. We are currently
investigating the cause.
