Influence of ground base station on accuracy of airborne light detection and ranging

This article briefly describes the various components of the airborne light detection and ranging system, and analyzes error factors of the system. According to the Mianyang-Chengdu-Leshan inter-city railway station line engineering data of different base stations, we have differential treatment of the airborne GPS (global positioning system). Detailed comparative analysis of the forward/reverse separation mean value/distribution and photo positional accuracy of the calculated flight trajectories is performed. Finally we arrive at the ground base station layout scheme to improve data accuracy.
