Abstract
Both GPS Computerized Ionosphere Tomography (CIT) and BackScatter Ionosonde (BSI) can provide two-dimensional electron density profile in large scale. Based on the result of three separate vertical ionosonde, GPS computerized ionosphere tomography and backscatter ionosonde, this paper compares the two-dimensional electron density profiles of GPS computerized ionosphere tomography and backscatter ionosonde. The results show that both methods reconstruct two-dimensional electron density profiles very well and reflect spatial structure of ionosphere. These two methods show high accuracy in the biggest electron density and peak height of F2 layer in contrast with the result of Vertical Ionosonde (VI).
