I received my first degree in automatic control from Beijing University of Chemical Engineering in 1994. I then worked as an electronic engineer for Beijing Control Technology Development Company and as a customer support engineer for Lenovo until I pursued my MSc study in UK. In 2004, I has successfully completed my MSc course in computing and information in the University of Bedfordshire and have been awarded an MSc with distinction.

Although doing a PhD is always considered to be very challenging thing to do, I would like to take the challenge after being a full-time mother for a number of years. University of Nottingham is always my first choice with its good reputation, especially, in the area of GNSS research. I believe there will be more career opportunities in GNSS area in future because satellite positioning and navigation is becoming part of ordinary people's life and there will be even more demanding of GNSS technology in future.

Research Summary

My research topic is integrating multi-constellation GNSS and terrestrial positioning technologies for autonomous machine control applications.

Recently, the Global Positioning System (GPS) has been integrated into the designs of bulldozers, drills, excavators, pavers, farming equipment and graders that are produced by most of the major manufactures for mining, construction, agricultural and environmental applications. GNSS antenna(s) are usually installed on the working tool for the existing systems, such as blade. It has been found that the antenna(s) on the blade is very easy to be damaged, which contributes to one of the highest maintenance costs. Therefore, it is highly desirable to move the GNSS antennas to the cabin roof because it is the safest place for the GNSS antenna installation. In order to move GNSS antennas away from the working tool, a platform, in which the antennas will be installed on the roof of driving cabin and far away from working tools, has been proposed. More specifically, in the proposed system, multiple GNSS receives are used for the cabin roof attitude determination and then integrated with other sensors' position solutions to obtain the position of the working tools.
