Abstract

Doppler Orbitography and Radio positioning Integrated by Satellite(DORIS) is a high precision satellite orbit determination and ranging system based on Doppler shift measurements from dual frequency signals propagated between ground stations and a satellite. The Doppler shift measured on the 2.036GHz signal and an additional 401.25MHz is a very potential means for scientific researches on ionosphere. In this paper, global Total Electron Content(TEC) measuring principle of the DORIS system is analyzed, and an algorithm is presented to derive the space variations of TEC from the DORIS ionospheric correction data. Finally comparison of TEC latitudinal profiles are done to with the NeQuick model. And some advices on the improvement of the DORIS system are put forward for advantaging ionospheric sounding and tropospheric sounding.
