China successfully launched the Shiyan Weixing-5 (SW-5) satellite into a preset orbit with the Long March-2D carrier rocket at 10:12 a.m. Monday at the Jiuquan Satellite Launch Center. The satellite will conduct technological experiments and environmental surveys. It is the 185th launch of the Long March series of carrier rocket. As previous launches from China, little information was released about this mission.
SW-5 uses the CAST-100 satellite platform and is possibly related to the medium size rapid surveying earth observation satellite platform that can house optical, SAR and other payloads for rapid target acquisition.
This was featured in one news article early in 2013 while mechanical tests were being performed on SW-5.
The first Shiyan satellite was launched on April 18, 2004, by a Long March-2C rocket from the Xichang satellite Launch Center.
This was China’s first experimental digital imaging system capable of stereo Earth-terrain mapping, also testing the digital imaging capability for the then new generation of Chinese military reconnaissance spacecraft in development.
