任务简介
JB-3 2 名义上是一颗中国（PRC）遥感卫星，但美国情报机构表示其主要执行情报成像任务。JB-3 2 是美国太空司令部采用的名称。中国及其他地区的大多数新闻报道使用不同名称：ZY-2B（ZiYuan-2B 的缩写，译为资源-2B）和 Zhong Guo Zi Yuan Er Hao，译为中国资源二号。JB-3 2 上搭载的仪器没有可用信息，但官方称其旨在“用于国土普查、环境监测与保护、城市规划、作物估产、灾害监测和空间科学实验”。
原文
JB-3 2 was nominally a Chinese (PRC) remote sensing satellite, although US intelligence sources indicated it had primarily an intelligence imaging mission. JB-3 2 was 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. No information was available on the instruments onboard the JB-3 2, but officially it was intended 'for territorial survey, environment monitoring and protection, urban planning, crop yield assessment, disaster monitoring, and space scientific experiments'.
