Abstract

Ionospheric anomaly in south of China will degrade the performance of SBAS grid models severely. Characteristics of ionospheric delay errors are analyzed with observations from the mid and low latitudes area in China for various solar activities and ionospheric conditions. Results show the error distribution is symmetric, unimodal, and overbounded by a biased normal error distribution. The biased distributions would reduce the overbounding capability of the estimated bounds. Ionospheric anomaly contribute to the complicated spatial and temporal variations of the delay errors as storms, and even is the main influencing factors under certain condition.
