Wideband InterNetworking engineering test and Demonstration Satellite
Anomaly in the Solar Sensor Signal Processing

Japan Aerospace Exploration Agency (JAXA)

At 4:00 p.m. on March 2, 2008 (Japan Standard Time, JST), 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.
