| Summary: | We estimated the receiver and satellite differential code bias (DCB) based on the ionospheric total electron content (TEC) estimation method. The GPS network which has been operated by the Korea Astronomy and Space Science Institute (KASI) was designed to calculate TEC. The receiver and satellite DCB values were obtained from the weighted least square method with time interval for one hour. The results represented that the receiver DCB values are mostly varying within ±2 meter and are derived comparatively stable within three days. The estimated mean values of the satellite DCB show the maximum and minimum values of 4.09 nano-second (ns), --6.28ns respectively. We could detect great variations of TEC over 9 TECU difference at any time when the DCB sets were applied to TEC estimation. |
