3D Modeling Of GNSS Vector Tracking Receiver in Urban Area

Abstract

3D maps may be treated as a new data source for urban navigation and used to improve positioning accuracy in urban canyons However, 3D digital maps are not available in most cities. This paper proposed a new approach to build a 3D model by using a GNSS VT receiver. The system architecture was described first, and then the method of 3D modeling by analyzing received data was presented. The premise for building the 3D model is signal classification. Analysis of data collected by the VT receiver was described in detail. Using a GNSS signal recorded in a dense urban environment showed the effectiveness of the proposed approach.
