Seamless Navigation in Urban Environment
This project developed an integrated solution to solve the multipath problem in Hong Kong. It integrates multiple sensors, including Micro-electromechanical Systems sensors, Wi-Fi, satellite in view, and multiple GNSS constellations together with 3D city model, to significantly reduce multipath effect by using advanced fusion algorithms and multipath modeling. With the project, we can significant increase coverage and reduce multipath errors in dense urban areas using the aforesaid algorithms. By integrating multipath mitigation methods developed in this project and DGNSS platform for mobile phone that was developed earlier, we are able to provide an integrated service to offer metre-level positioning accuracy in open areas and 10 meters accuracy in dese urban areas in Hong Kong.
This solution has won a Silver Medal in the Special Edition 2021 International Geneva Evaluation Days.
