China launched a new high-resolution remote sensing satellite capable of providing stereoscopic imagery on Sunday, state-run media said, marking another important step as Beijing seeks to reduce reliance on foreign technology in topographic mapping.
A rocket lifted off from the Taiyuan satellite launch centre in northern China at 11:22am local time, carrying the Gaofen-7 high resolution satellite into its designated orbit, the state-run CCTV said, citing China National Space Administration. Gaofen-7, a sub-metre resolution optical satellite, boasts the highest mapping accuracy among domestic peers, and can map China and even the world’s lands stereoscopically with a margin of error of less than a metre, according to CCTV. The satellite, which will be used for land surveys, urban planning and statistical investigation, will help end China’s reliance on foreign imports in high-resolution stereo mapping, CCTV added. The purpose of China’s satellite remote sensing project—the Gaofen series—is to help build an all-weather, 24-hour, global Earth remote sensing system by 2020 capable of monitoring the ground, atmosphere and oceans, CNSA said.reuters
