| 摘 要： | 在GPS网络RTK中,利用不同的内插算法,生成的流动站误差改正数不同,它们对定位结果的影响也不同。通过算例分析表明,选择合理的内插算法,不仅可以生成与流动站真实误差较为接近的误差改正数,还可以提高整周模糊度的解算成功率和导航定位的精度。

| Abstract: | Different correction terms of moving station and influences on positioning can be generated when different interpolation methods utilized in GPS-network RTK.The paper gives a test in the end,test results show that it can not only gain correction terms which will be close to real errors of moving stations but also improve the successful ratio of fixing ambiguities and precision of navigation and positioning if reasonable interpolation methods are selected. |
