This paper shows a simulation process of retrieving ionospheric electron density from the Global Positioning System/Meteorology (GPS/MET) to examine the accuracy of the retrieval procedure for the COSMIC project3 during solar minimum and maximum periods. Results show that the error of the maximum electron density (NmF2) is under 25%, and the error is greater in the solar maximum than in the solar minimum period. The mean error of the height of NmF2 (i.e. hmF2) is less than about 13 km and seems to have no correlation with solar activity.3A Taiwan-US joint project for Constellation Observing System for Meteorology, Ionosphere, and Climate.
