利用GPS双频码观测值进行最小二乘平差估计tec（总电子含量）。电离层在350km高度采用局地或全球tec模型近似为单层模型。估计卫星/接收机dcbs（差分码偏差）以及tec模型系数。
Estimate tec (total electron content) by least-sqaure adjustment using GPS dual-frequency code observables. Ionosphere is approximated as the single- layer model at the height of 350km with local or global tec model. Satellite/receiver dcbs (differential code biases) are estimated as well as tec model coefficients.
