Ionospheric critical frequency observation from ionosonde data for GPS positioning improvement over Malaysia

This research work was done to determine the critical frequency, fc, variation over Advanced Telecommunication Research Center (ATRC) UTHM by identifying the variability of the ionosphere from Ionosonde. The ionospheric variability was analyzed on diurnal variation basis at Low Solar Activity (LSA)...
