	| Abstract | 
	This paper investigates an integrated navigation framework based on effective 2D point cloud data considering the under-bridge environment. The proposed method newly devised an integration framework in the GPS-challenged environment under bridge through combining horizontal point cloud data and inertial measurements. In this, the efficiency of data processing and integration was substantially reflected for the real-time navigation performance. In order to consider various bridge environments, we explored the bridge geometry and map approximation to realize the practical application possibility of the proposed algorithm. Finally, a detailed bridge environment simulator study was conducted to validate the performance of the proposed technique.  |
