Analysis of Higher-order Ionospheric Effects on CMONOC Coordinate Variations
Abstract By designing different scenarios, we can solve stations of CMONOC, in order to analyze the influences of higher-order terms ionospheric delay and receiver clock error to CMONOC stations’ coordinates, and the differences of higher-order terms ionospheric delay's effect under different geomagnetic models. The results show that as solar activity becomes more active, the change of higher-order terms ionospheric delay to CMONOC stations' vertical coordinates can reach 1.2 cm. The influence on the receiver clock error is close to 4.4 mm, the influences of the higher-order ionospheric delay model under different geomagnetic conditions are little. Finally, we discuss and analyze the effect of latitude, baseline length and direction to the higher-order terms ionospheric delays.
Key words :
higher-order terms ionospheric delay
