Project Title: Development of a Hong Kong Positioning Infrastructure based on GPS, Beidou, and Ground based Augmentation System
Hosting Institution: The Hong Kong Polytechnic University (PolyU)
Abstract: Since 2001, the Lands Department of HKSAR government has developed a GNSS active control network (Hong Kong Satellite Positioning Reference Station (SatRef) network) to support high accuracy positioning in Hong Kong. This project aims at developing a fundamental positioning infrastructure to provide multiple location based services to support economic development in Hong Kong, based on the existing Hong Kong SatRef network. The objectives of this project are: 1) to further enhance the performance of the SatRef network by integrating GPS and Beidou - the Chinese satellite navigation system, to achieve more reliable Real-Time Kinematic (RTK) positioning with the accuracy of 1 centimetre for survey and engineering applications; 2) to implement GNSS heighting in Hong Kong to improve engineering surveying efficiency; 3) to provide a reliable platform with DGNSS technologies for mobile operators in Hong Kong and surrounding territories to support personal and vehicle navigation with the accuracy of one metre. The completion of this project will provide a reliable and high precision augmentation system to support the technology advances in surveying, logistics operation, Geographic Information System (GIS) applications, and location-based services in Hong Kong. Also, as the Beidou system is developed by China, and the Chinese government would strongly encourage the widespread use of the system for national. In China, the GPS RTK networks have been established in all the major cities and provinces. The technologies developed in this project can be directly applied to those networks.
