JB-3 2



JB-3 2 is a Chinese (PRC) remote sensing satellite that was launched by a Long March 4B rocket from Taiyuan Satellite Launch Center (TSLC) at 03:17 UT on 27 October 2002. JB-3 2 is the name adopted by the USSPACECOM. Most news reports from China and elsewhere use different names: ZY-2B (acronym for ZiYuan-2B, translated as Resource-2B), and Zhong Guo Zi Yuan Er Hao, translated as China Resource 2. There has been a Zhangguo Ziyuan 2 (2000-050A) obviously omitting the "A" after "2", condensed by the USSPACECOM as ZY 2. No information is available on the instruments onboard the JB-3 2, but it is intended "for territorial survey, environment monitoring and protection, urban planning, crop yield assessment, disaster monitoring and space scientific experiment".
