Abstract The ionosphere delay is an important source of error in GPS measurements. TEC can be calculated by using dual-frequency GPS observations, and then highprecision region Ionosphere Model can be established. The quality of GPS observations and satellite elevation angle are closely related and different data processing methods have some influence on the results. Two different weighting methods are used and their results are analyzed .It shows that using a high elevation angle for weighting will get more accurate results.
