TECDEMO ver.0.2 2006/02/25 by T.TAKASU (ttaka@gpspp.sakura.ne.jp)
1.Description
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.
