Abstrakt
The paper deals with comparison of two different methods for checking of automatically scaled ionograms. The first method is based on application of moving average filters on ionospheric characteristics. The second method uses complementary system for measurement of the ionospheric Total Electron Content (TEC). We show that both methods are comparable. However, the moving average filters based method gives slightly better results.
