| Abstract: | RTK positioning technique based on carrier phase observations can acquire centimeter level positioning accuracy,while,the key technique is to fast fix ambiguities and compute the ambiguity parameters on kinematic condition.LAMBDA method which fixs ambiguities quickly is adopted to finish initialization,and cycle slip is detected in real time;then,new ambiguities are searched and fixed.A software is programed with C++ to realize this algorithm.By testing the field data,this method and software are verified t... |
