Senior Research Associate

Developed a preprocessing system (mainly including geometric correction,

radiometric correction, and image mosaic) of satellite remote sensing images.

Particularly, designed and programmed the geometric correction modules,

establishing mathematical models of spaceborne CCD cameras.

Established a satellite remote sensing data receiving, processing, and archiving

system. Participated in a two month training course held at Macdonald Detwiller and

Associates (MDA) ltd., Canada for understanding of the system.

Performed system engineering for space mission design and satellite development.

Developed electrical power systems for small satellites, KITSAT-2 and KITSAT-3.

Established a long-term strategic plan for the research center.

Managed research and development teams for satellite subsystem design and

manufacture and leaded a strategy planning team.
