Ambiguity resolution to multi-frequency carrier phase observations under RTK Mode
Wu Yu · Engineering of Surveying and Mapping · 2013
The key technologies of multi-frequency ambiguity resolutions are studied under GPS modernization.The L5carrier 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.
