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。
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.
