| 摘 要： | 为了提高接收机码间偏差的计算效率和精度,利用CODE中心发布的全球VTEC地图和卫星码间偏差,通过内"预测-校正"法快速解算接收机码间偏差,并结合VTEC多项式对内插结果进行误差项改正。新算法解算的码间偏差与IGS发布的数据差值基本维持在0.2 ns以内,表明该算法计算精度较高,且效率明显高于传统方法。

A New Algorithmfor Fast Solving Receiver DCB |
| |
| Abstract: | In order to improve the computational efficiency and precision of the receiver DCB,put forward using the CODE center released global VTEC maps and satellite DCB,calculating receiver DCB by "remove-restore",and combining the VTEC polynomial internally inserted result error correction.Between the new algorithm of calculating DCB values and IGS data maintained within 0.2 ns of error,show that the new algorithm precision is higher and efficiency is significantly higher than the traditional method. |
