许多野生动物都有着神奇的迁徙本能,人们常常为它们在长途跋涉中表现出来的近乎完美的导航本领而赞叹不已,同时也梦寐以求着人类在某一天也能具有这样的能力.从远古时代的黄帝战蚩尤时.发明了第一种定问工具“指南车”开始,在其后漫长的年代里,人类相继发明厂磁罗盘、六分仪、无线电定位导航系统和惯性导航系统.然而,由于受到导航定位精度、导航作用范围、气象环境影响等等限制,这些导航系统还不能完全满足人类的需要.直到二十世纪九十年代,一种全新的高精度授时导航定位系统诞生了,它就是被人们称之为二十世纪九十年代人类最伟大的一百项重大科技成就之一的GPS全球卫星定位导航系统.
Many wild animals have miraculous migratory instincts, and people are often amazed at the near-perfect navigational skills they show in their long journey, while also dreaming of humankind’s ability to do so on a single day. In the long years since then, human beings have successively invented the magnetic compass, sextant, radio positioning navigation system and inertial navigation system. However, due to the fact that Navigation and positioning accuracy, the scope of navigation, weather and other environmental constraints, these navigation systems can not fully meet human needs until the 1990s, a new high-precision time-service navigation and positioning system was born, it is People call it the GPS global positioning satellite navigation system of one of the greatest hundred hundred major scientific and technological accomplishments of mankind in the 1990s.
