Abstract The establishment and data processing of ionospheric model based on the integration of GPS/GNSS systems were introduced in the paper.The result of analysis for influence of adding GLONASS data on global ionospheric model taking the result of 001~031 days in 2010 as an example indicates that combination of GPS and GLONASS data does not improve accuracy,on the contrary,the RMS at grids points is increased due to the influence of weaker quality during GLONASS observing.
