Abstract:	Raw data of several reference stations, which are equiped with cross correlation receivers, are col- lected with at last 10 Hz data rate to estimate the iono- spheric delay in the observed region during one week of September 1994. Firstly the collected raw data per station are analyzed with regard to multipath, noise, cycle slips and track- ing losses. The correlation between measurements under the same observation conditions are discussed to demonstrate the modified steps in preprocessing and real time processing to get a cleaned pseudo ion- ospheric delay as a sum of receiver bias, satellite bias and true ionospheric delay. The influence of proces- sing parameter like elevation mask and data rate are shown. To subdivide the pseudo ionospheric delay it’s neces- sary to estimate the satellite and receiver biases. The developed algorithm is applied to all participated sta- tions and to several combinations of stations to rec- ognize the stability of the estimation and it’s depen- dence of processing parameter and used stations. The such estimated receiver and satellite biases are used to calibrate the stand alone solutions of every reference station. Snapshots of the ionospheric behaviour about the observed region are given and discussed.
