人类至今已先后将5000多颗卫星、飞船、航天飞机和空间站等航天器送入太空。然而,太空并未因此变得杂乱无序。一个神奇的力量引导着这些航天器始终按照自己的轨道飞行,偶尔偏离轨道,也能很快“迷途知返”;一旦发生了故障,就能得到及时抢救和精心照料;即使意外失控陨落,人们也能及早预知,防患于未然。这个神奇的力量就来自庞大的地面测控网。由于特殊的地理位置和航天政策,中国的地面测控网更具特色。在“神州”5号飞船发射成功并顺利返回地面之际,为使广大读者了解中国的地面测控网,我们特组织刊发此稿。
So far, more than 5,000 satellites, spacecraft, space shuttle and space station spacecraft have been sent into space by mankind. However, space has not become cluttered. A magical force guides these spacecraft to always follow their own orbit, occasionally deviate from orbit, and can quickly “go astray”; in the event of a fault, they can get timely rescue and meticulous care; even if the accidental fallout, people Can also predict early, take preventive measures. This magical power comes from a huge network of ground monitoring and control. Due to its special geographic location and space policy, China’s land survey and control network is more unique. On the occasion of the successful launch of “Shenzhou” spacecraft No. 5 and its smooth return to the ground, we have published this draft for the benefit of readers in China.
