【摘要】 随着自动驾驶技术的快速发展与应用,无人系统的车载需求日益上升,而高精度定位是无人系统安全与实用的重要前提。本文基于实地跑车实验,在车载静态、车载动态环境下,对集成模块和组合模块两种不同组合方式的UBLOX定位模块精度进行分析。在车载静态实验中,集成模块和组合模块平面位置精度分别为0.5m和2m;二者的速度精度均在0.5m/s内。在车载动态实验中,集成模块在东向和北向上的位置精度均在2m内,组合模块分别在10m、15m以内;在速度精度方面,二者均在2m/s内。综上,在常见车载环境中,集成模块定位精度均优于组合模块定位精度,本文的研究结果对用户选择定位模块的组合方式提供了一定的帮助。更多还原

【Abstract】 With the development and application of autonomous driving technology, the vehicle demand of unmanned system is increasing. And high-precision positioning is an important prerequisite for the safety and practicality of unmanned system. In this study, we analyze the accuracy of UBLOX positioning module in two different combinations of integrated module and combined module in vehicle both static and dynamic environment. In the vehicle static experiment, the plane positioning accuracy of integrated module is 0.5 m, while combined module is 2 m. They have the same speed precision within 0.5 m/s. In dynamic testing, the accuracy of integrated module is within 2 m both in east and north. In combined module, it is lower with 10 m in east and 15 m in north. In speed, both are less than 2 m/s. In summary, the positioning accuracy of integrated module is better than that of combined module in the common vehicle environment both static and dynamic, which may help users to select the combination of positioning modules.更多还原
