ABSTRACT In this study, the first results of the next-generation dual-frequency multi-constellation SBAS-based kinematic positioning in Australian urban environments are presented and analysed. As the standalone GNSS positioning is unable to deliver the accuracy required for absolute positioning in Intelligent Transport Systems (ITS), more advanced technologies are needed, and the Australian SBAS with PPP capabilities is a candidate. Kinematic tests were run in scenarios characterised by four environments: high-density urban, low-density urban, suburban and tree-canopy. SBAS positioning performance was evaluated in the different environments, with a focus on its capability to provide lane identification and thus aid ITS applications.

在澳大利亚城市和郊区道路环境中使用第二代 SBAS 的初步结果

摘要 在这项研究中，介绍和分析了澳大利亚城市环境中基于下一代双频多星座 SBAS 的运动学定位的第一个结果。由于独立的 GNSS 定位无法提供智能交通系统 (ITS) 中绝对定位所需的精度，因此需要更先进的技术，具有 PPP 功能的澳大利亚 SBAS 是候选者。运动学测试在具有四种环境特征的场景中运行：高密度城市、低密度城市、郊区和树冠。SBAS 定位性能在不同环境中进行了评估，重点是其提供车道识别的能力，从而有助于 ITS 应用。
