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.
