英文摘要	To achieve decimeter or even centimeter high precision positioning solutions, correct carrier phase observations and rapid convergence, generally 30 minutes under normal occasions are necessary. So the integer ambiguity associated with carrier phase must be resolved reliably and quickly. With the development of GNSS, users can get carrier phase data of more frequencies which will help to reduce time and provide more opportunities for reliable ambiguity resolution, because they can form more frequency combinations with longer wavelengths. However, in spite of significant research in the development of efficient algorithms for multi-frequency carrier phase ambiguity resolution, full performance potential of the additional frequency signals cannot be demonstrated effectively without actual multi-frequency data. We investigate traditional ambiguity resolution methods with real GPS data. According to the results, this study provides a modified method using the linear combinations of carrier phase measurements to determine the ambiguity resolutions and test it with real data. It can provide a efficient solution without using reference stations.; State Administration of Science, Technology and Industry for National Defense [JCKY2016110B004]; CPCI-S(ISTP); 459-463
