| Abstract: | Galileo system is one of the commonly used positioning systems at present. This paper uses self-edited software to carry out a dual-frequency and triple-frequency short baseline solution experiment of Galileo system under the condition of non-combined model. Research has found that for a 9 km short baseline, the Galileo dual-frequency short baseline solution under the non-combined model has a horizontal accuracy better than 5 cm, and an elevation accuracy better than 10 cm. The triple-frequency combined solution accuracy is significantly improved compared with that of dual-frequency. The horizontal accuracy is better than 3 cm. The elevation accuracy is better than 4 cm. |
