Bio

Qi Liu was born in China in 1997. He received his Bachelor's degree from Southeast University (SEU) in 2019. Since then, he has been taking a successive posgraduate and doctoral program in the BDS Navigation and Positioning group of SEU. From February 2023 to February 2024, he was a visiting researcher at the SPCOMNAV research group.

On November 3, 2024, he completed his PhD entitled "Research on Key Technologies of Smartphone Adaptive Positioning for Multiple Scenarios" at SEU.

Research interests

His research interests lie in the field of satellite and terrestrial positioning using GNSS and 5G technologies, now extended with the use of LEO satellites, either for dedicated PNT or as a source of signals of opportunity (SOP).
