2002. 10 to present: innovative researcher, institute of geodesy, China academy of sciences (1)GPS space environment (ionosphere and troposphere).

(2) The theory and method of 2)GPS navigation positioning and orbit determination.

(3) The theory and method of 3)GPS measurement data processing.

(4) Modern measurement error theory

(5) Name of GPS Software and High-tech Application Project: Study on the Theory and Method of Ionospheric Delay Correction for Manned Spacecraft's Integrated Precise Orbit Determination.

This project has formed its own research characteristics in the field of GPS ionospheric delay correction theory and method, and its research level is in a leading position in China and has reached the international advanced level. Some achievements have been called "important original contributions" by international authoritative experts, especially the two comprehensive ionospheric delay correction methods for precise orbit determination of spaceborne single frequency GPS-IGGIRI scheme and APR-II scheme, which have great innovations and advantages in theory. It has also made a breakthrough in technology, solved some of the most difficult key technical problems in the precise orbit determination of Shenzhou IV spacecraft, played a key role in the precise orbit determination of manned spaceflight project and made important contributions. This achievement won two second prizes for military scientific and technological progress.
