A Calculation Method of Ionospheric TEC Using Triple-Frequency GNSS Observations
Abstract Triple-frequency GNSS observations with different frequency combinations are used to obtain ionospheric TEC. Corrections to hardware delay are made using the product provided by IGS. The results show that TEC offsets using observations of different frequency combinations are significantly reduced after applying IGS hardware delay corrections. Furthermore, a method for producing the final TEC is proposed.
Key words :
