Abstract

Hong Kong and Macau's dense skyscrapers and narrow streets create the most challenging environment for satellite based vehicle positioning systems (VPS). In order to evaluate how modern vehicle positioning technologies perform in such an environment, various field tests have been conducted, which include Satellite based sensors, including GPS and a combination of GPS and GLONASS; and Satellite based systems aided with DR. Various data processing algorithms have also been investigated based on the data obtained from the above tests. This paper reports some testing results on vehicle positioning based on GPS and its integration with other sensors. Preliminary results from the tests show that less than 30% of areas in Hong Kong are visible to sufficient GPS satellites, and about 60% of the areas can be positioned if GPS and GLONASS are combined. It is also shown that when DGPS is aided with the DR, the real-time vehicle positioning accuracy can reach an order of approximately 20 metres. For the covering abstract see ITRD E114174.
