| 摘 要： | 探讨了GPS长距离基线精确解算方法及其解算精度与观测时间的关系.研究表明,充分利用载波相位各组合观测值特点的L5-L3解法比L3解法好;长距离基线解算时,观测时间达到一定长度后,其精度趋于稳定,再观测更长时间精度提高很少,甚至不提高. |
| 关 键 词： | GPS 长距离基线 精度 组合观测值 |

| Abstract: | In this paper,firstly,methods for resolving precisely GPS long distance baselines are discussed.It shows that L5-L3 method is better than L3 method,because the former uses properties of some combinations of GPS dual frequency carrier phase observations fully.Secondly,the relation between the precision of GPS long distance baselines and their observing time is discussed. It can be seen that the precision becomes more and more stable when observing time is enough long (about 4 h),and that the precision is not improved more when the time prolonged further. |
