中国发射两颗巴基斯坦卫星
China launched two satellites for Pakistan on a Long March-2C rocket from the Jiuquan Satellite Launch Center in northwest China at 11:56 a.m. Monday.
本周一上午11点56分，中国在酒泉卫星发射中心用一颗长征长征二号C火箭将两颗巴基斯坦卫星送入太空。
The PRSS-1 is China's first optical remote sensing satellite sold to Pakistan and the 17th satellite developed by the China Academy of Space Technology (CAST) for an overseas buyer.
A scientific experiment satellite, PakTES-1A, developed by Pakistan, was sent into orbit via the same rocket.
After entering orbit, the PRSS-1 is in good condition with its solar panels unfolded smoothly, according to CAST.
The PRSS-1 will be used for land and resources surveying, monitoring of natural disasters, agriculture research, urban construction and providing remote sensing information for the Belt and Road region.
The satellite, which has a designed life of seven years, is equipped with two panchromatic/multispectral cameras, with a resolution up to a meter and a coverage range of 60 km.
Designers say the two cameras are among the best exported remote sensing cameras made by China. They can be used to monitor plant diseases and pests.
Each camera has independent image processing, storage and transmission capability. The design of lossless compression could greatly improve the quality of the images, according to designers.
A specially designed orbit will ensure the satellite operates steadily and will optimize the image quality.
