Experience:
- 2004 - present: Senior Research Fellow at the School of Surveying and Spatial Information Systems, University of New South Wales (UNSW), Australia. Current focus is the development of a GPS/INS/Locata triple integration device.
- 2002 - 2004: Research Fellow at the Royal Melbourne Institute of Technology (RMIT) university, Australia. Responsibility at RMIT was to develop a GPS-based multisensor integrated system for sport applications.
- 2000 - 2002: STA Research Fellow supported by a Japanese STA Fellowship at the National Aerospace Laboratory of Japan (NAL, now the Japanese Aerospace Exploration Agency JAXA), focused on the development of a GPS-based attitude determination for a spaceplane.
- 1999 - 2000: Senior Engineer at the Beijing Institute of Control Engineering (BICE), Chinese Academy of Space Technology. At BICE concentrated on the development of a spaceborne GPS-based attitude determination system; GPS-based device for spacecraft rendezvous and docking; and involved in research on the Chinese 2nd generation satellite navigation system (now known as COMPASS).
- 1997 - 1999: Postdoctoral Research Fellow at BICE, focused accurate attitude determination using GPS for satellites.

-
Hands-on skills and engineering experience on GPS mobile/autonomous /aircraft/spacecraft applications.
Past Projects:
-
FPGA-based Real-time GPS/INS Device. Implemented hardware and software for the time-synchronization, and the tight/loose integration Kalman filtering, under the Australian CRC-SI Project 1.3 “Integrated Positioning and Geo-referencing Platform” (2004 – 2007, UNSW).
-
GPS for Sport Applications. Developed 10Hz precise PVA (position, velocity and acceleration) algorithm, implemented prototype system, and software packages on Windows and iPAQ, under the Australian CRC for microTechnology Project 2.5 “Interface Technology for Athlete Monitoring” (2002-2004, RMIT).
-
GPS-based Attitude Determination. Developed a GPS attitude determination receiver for space applications, implemented a C/C++ library for GPS based attitude determination algorithm (1997-2000, BICE). Algorithm development for a JAXA’s spaceborne GPS attitude determination receiver (2001-2002, NAL). Implemented an attitude determination device using two AllStar GPS OEM boards for a satellite based medical service system on ambulance (2000-2002, NAL).
-
GPS Relative Navigation for spacecraft rendezvous and docking. Developed algorithm and a prototype system by combination of GPS pseudorange, Doppler, and carrier phase measurements (1997-2000, BICE).
-
GPS/AHRS integrated system. Developed a prototype system and software packages (1995-1996, NWPU).
-
DMAS software. Windows-based software developed for the Data Management and Analysis System for the Long-March series rockets, implemented DSP in frequency and time domains, including spectrum analysis, frequency filtering, and later extended with Kalman filtering and RTS smoothing (1995 – 1996, NWPU).
-
GPS/Digital Map Integrated System. The outcome of the project was awarded “Awards to the Progress in Science and Technology” by the Chinese Aviation Industry Corporation in 1993 (1991-1993, NWPU).
