| Abstract: | Starting from the common LAMBDA algorithm with baseline length constraint,a combined search method of ambiguity resolution is put forward,which enhances the success rate and reliability and ensures the validity and usability of the single epoch algorithm.The results of calculation of several groups of GPS data indicate that the single epoch algorithm with dual-frequency data can get very high success rate and heading accuracy,and demonstrate that the GPS heading determination algorithm is feasible and reliable in practice. |

| Keywords: | GPS heading determination dual-frequency data single epoch algorithm |
