Abstract:On the basis of the GPS observations obtained at the Wuhan IGS station of CMONOC, the TEC and ROT of satellite transmission path on July 22 and the days before and after it were calculated. The results show that ionospheric anomalies existed during the solar eclipse, the TEC is lower than those on the days before and after it.8 hours after the solar eclipse, the ROT experienced a process of going down and recovery, the largest degradation is almost 0.3TECU/minute.
