摘　　要：在GPS现代化下,研究多频卫星导航定位的关键技术,利用现有的双频观测值去模拟L5载波相位观测值,然后根据网络RTK基准站连续观测的特点,利用基准站坐标精确已知的条件,研究多频模式下基准站间的整周模糊度求解。通过分析,在不同基线长度下,多频模式下的基准站间模糊度求解比双频模式下更加可靠,求解整周模糊度更加便捷。The key technologies of multi-frequency ambiguity resolutions are studied under GPS modernization.The L5 carrier phase observations are simulated by using the existing dual-frequency observations.Then according to the characteristics of the continuous observations of network RTK,the ambiguities between base stations are resolved by use of multi-frequency.By analyzing the different baseline length,ambiguity resolutions in multi-frequency mode are more reliable and more convenient.
