Abstract: In this paper, the GPS network of Nanning rail transit is adopted as an example. The relative ionospheric model is adopted in consideration of the ionospheric activity in Nanning. The short period variation of the ionospheric delay in each station is analyzed, compared with the values release by the authoritative organization. Some conclusions are made finally.

Key words: ionosphere, delay, GPS network, urban rail transit
