| 摘 要： | GPS卫星无线电导航系统预计在1995年投入正式运行。GPS信号中的P码仅供美军和特别用户使用,C/A码则向全世界民用开放。C/A码受选择可用性(SA)影响,导航静度下降到一个适当水平。为提高GPS定位精度,各国都争相研究差分GPS(DGPS)。本文从GPS误差入手,主要就DGPS原理和实现方法进行讨论。

| Abstract: | It is predicted that GPS-the satellite navigation system will come into useby 1995.While the P code of GPS signals will be used exclusively by the U.S.militaryand other special users,the C/A code Will be open to civil users all over the world.Sincethe SA affects the accuracy of the C/A code,many countries are studying differential GPSin an effort to improve the positing accuracy of GPS.Beginning with the GPS errors,thispaper discusses the theory and implementing method of differential GPS. |
