"KIZUNA" (WINDS) Anomaly in the Solar Sensor Signal Processing
At 4:00 p.m. on March 2, 2008 (Japan Standard Time, JST [0700 UTC]),
the Japan Aerospace Exploration Agency (JAXA) found an anomaly in the
signal processing of the main system of the sensor that detects the
direction of the Sun (Sun sensor) onboard the Wideband Internet working
engineering test and Demonstration Satellite, KIZUNA (WINDS,) which
was launched on February 23, 2008.
Currently the satellite attitude is stably controlled with its Earth
sensor (which detects the direction of the Earth) and the gyro.
JAXA is investigating the cause of the anomaly while revising the
operation process in order not to cause any trouble for the future
operation of the satellite.
