Determination of nighttime VTEC average in the Klobuchar ionospheric delay model
The Klobuchar model has been widely used to correct the ionospheric delay in applications. However, the NVTEC (Nighttime Vertical Total Electron Content) of the Klobuchar model employs an empirical constant of 9 TECU (Total Electron Content Unit) at L1 frequency. In this paper, the rationality and r...
