I am currently an Assistant Professor in the Department of Aeronautical and Aviation Engineering at The Hong Kong Polytechnic University. I received my BEng degree from Nanjing University of Science and Technology (NJUST), China, in 2012, and obtained my PhD degree in Control Science and Engineering also from NJUST in 2018. Prior to my current position, I held roles as a Postdoctoral Fellow and Research Assistant Professor in the AAE department at PolyU.
Our lab is focused on positioning, navigation, and timing (PNT) research, specifically concentrating on PNT signal processing. These signals include GNSS, cellular, low-Earth orbit satellite signals, and various other signals that can contribute to PNT. Our aim is to improve the accuracy of positioning and navigation, especially in challenging environments like urban areas, and to enhance the security of positioning and navigation, which is crucial for applications such as autonomous driving, low altitude vehicles, and others.
Our research received support from the Hong Kong Research Grants Council (RGC), National Natural Science Foundation of China (NSFC), Guangdong Basic and Applied Basic Research Fund, among others. We also collaborate with industry partners to implement our technologies into real-world products.
I am currently seeking enthusiastic new PhD students, Postdocs, and Master students. If you have a strong interest in our research area, please send me 1) a statement about your research, 2) your CV, 3) transcripts, and 4) any other supporting documents.
PhD candidate, Sergio, will present his research on GNSS positioning with multicorrelator as an alternative to direct position estimation (DPE) at ION Pacific PNT conference, which will take place from April 13 to 16, 2026, in Hawaii. Visit Section B6 Emerging PNT Consumer Applications on Wednesday, April 15, 2026.
23 Feb 2026Our paper on golden section (GS) search-based GNSS multipath mitigation for enhanced urban positioning is now available at IEEE Xplore. We use the GS algorithm to directly estimate the direct-path code delay under multiple reflections and even when the reflections are dominant.
23 Jan 2026We proposed an OFDM-based LEO navigation signal and validated its navigation performance with simulations and experiments. By jointly designing the signal and receiver, we achieve high-precision ranging with relatively low complexity under low SNR and large carrier frequency offsets. The paper is accessible in the journal NAVIGATION.
