摘要
介绍了北斗卫星导航系统的发展和地理国情监测中的基本情况。通过北斗卫星导航系统单点定位解算验证系统精度。分析了卫星数量、PDOP值、多路径效应、位置精度和速度精度,表明北斗卫星导航系统和GPS系统的定位精度相当。
The development of BEIDOU satellite navigation system and general information of geography national condition monitoring.The BEIDOU satellite navigation system accuracy is verified by single-point positioning.The satellite number,PDOP value,multipath effect,position accuracy and velocity accuracy are calculated.The results indicate that the accuracy of BEIDOU satellite navigation system is the same as the GPS.
