Real-time GPS Ionospheric TEC Estimation over South Korea
Ionosphere is one of the largest error sources when the navigational signals produced by Global Positioning System (GPS) satellites are transmitted. Therefore it is very important to estimate total electron contents (TEC) in ionosphere precisely for navigation, precise positioning and some other a...

Ionosphere is one of the largest error sources when the navigational signals produced by Global Positioning System (GPS)
satellites are transmitted. Therefore it is very important to estimate total electron contents (TEC) in ionosphere precisely
for navigation, precise positioning and some other applications. When we provide ionospheric TEC values in real-time, its
application can be expanded to other areas. In this study we have used data obtained from nine Global Navigation Satellite
System (GNSS) reference stations which have been operated by Korea Astronomy and Space Science Institute (KASI) to detect
ionospheric TEC over South Korea in real-time. We performed data processing that covers converting 1Hz raw data delivered
from GNSS reference stations to Receiver INdependent Exchange (RINEX) format files at intervals of 5 minutes. We also
analyzed the elevation angles of GPS satellites, vertical TEC (VTEC) values and their changes. |
