Sažetak
Total Electron Content (TEC), proportional to the ionospheric error in Global Navigation Satellite Systems (GNSS), can be calculated using dual-frequency measurements. To improve the calculation accuracy TEC should be calibrated, i.e. the inter-frequency biases introduced in the satellites and the receiver should be removed. Data from GNSS reference stations is publicly available in Receiver Independent Exchange Format (RINEX). Several software tools can be used to process such files. Modifying pseudoranges and carrier-phase data by removing the calibrated TEC, a version of the original RINEX file that does not contain ionospheric error was made. Modification procedure’s validity was proven by performance evaluation in position domain. Such a modified RINEX file could be used as a reference in comparison of different ionospheric error correction methods in position domain, where the methods would also be represented forming RINEX files modified following the same procedure.
