環(huán)境監(jiān)測(cè)衛(wèi)星

environmental monitoring satellite

　　China has successfully launched two environmental monitoring satellites, the HJ-2A and HJ-2B satellites, from the Taiyuan Satellite Launch Center.

　　The HJ-2A and HJ-2B are 16-meter optical satellites with high mobility, precision control and stability, as well as strong load adaptability and long lifespans.

　　They will support the monitoring of natural disasters and land utilization, regulation and protection of water resources, dynamic monitoring of crop areas and assessment of yield, as well as quake emergency rescue.

　　中國從太原衛(wèi)星發(fā)射中心成功發(fā)射了HJ-2A和HJ-2B兩顆環(huán)境監(jiān)測(cè)衛(wèi)星。

　　HJ-2A和HJ-2B光學(xué)衛(wèi)星，長(zhǎng)16米，具有移動(dòng)性 強(qiáng)、控制精度高、穩(wěn)定性高、負(fù)載適應(yīng)性 強(qiáng)、使用壽命長(zhǎng)等特點(diǎn)。

　　這些衛(wèi)星將強(qiáng)化對(duì)自然災(zāi)害、土地利用和水資源的監(jiān)測(cè)，為作物面積的動(dòng)態(tài)監(jiān)測(cè)和產(chǎn)量評(píng)估以及地震應(yīng)急救援提供支持。
