摘要 在全球导航卫星系统(GNSS)网络RTK综合误差内插法(CBI)的基础上,提出了一种改进的综合误差内插方法(MCBI)。该方法把综合误差分为对流层模型改正、一阶电离层影响和除一阶电离层影响外的其他综合影响3个部分。实例证明了该方法不仅在精度上比综合误差内插法要高,而且更利于流动站的应用。 On the basis of the combined bias interpolation (CBI) method of GNSS network RTK, a modified combined bias interpolation (MCBI) method is proposed. MCBI computes the troposphere delay using the troposphere model and estimates the first order ionosphere delay. Then MCBI separates the combined bias into three parts: the first order ionosphere delay, the troposphere delay computed by troposphere model and residual error. The example shows that the precision of MCBI is higher than that of the CBI and very convenient to use.
