Abstract:

Recently, according to the requirements of some im portant GPS research subjects in the fields of Geodesy, Geophy sics, Space -P hysics and Navig at ion in China, w e studied systematically how to correct the ef fects of the ionosphere on GPS, wi th high precision and accuracy.As the parts of t he main contributions, the research projects focus mainly on how to improve GPS survey by re-ducing ionospheric delay fo r dual/single f requency kinematic/static users :high accuracy co rrection of ionospheric delay for single/dual f requency GPS users on t he eart h and in space, China WAAS ionospheric modeling and the theory and met hod of monitoring of ionosphere using GPS.
