标准摘要
[中文适用范围]： 完整描述 本文档规定了使用基于网络的陆地交通精确定位基础设施 (NETPPI-LT) 进行车道级定位和完整性监控的游牧设备的功能要求，NETPPI-LT 是基于 ISO/TR 22086-1 中描述的全球导航卫星系统 (GNSS) 的车道级定位系统。本文档确定了要监控的 GNNS 威胁以及要消除或减轻的错误，以实现车道级准确性和完整性。它还规定了游牧设备和提供 GNSS 校正和完整性信息的控制站之间的消息中应包含的数据集。此规范使游牧设备能够支持车道级定位和完整性监控。本文档未涉及每个提供商或供应商可能不同的启用技术和方法。 [外文原描述]： This document specifies the functional requirements of nomadic devices for lane-level positioning and integrity monitoring with the network-based precise positioning infrastructure for land transportation (NETPPI-LT), a lane-level positioning system based on global navigation satellite systems (GNSS) described in ISO/TR 22086-1. This document identifies the GNNS threats to monitor and the errors to remove or mitigate to achieve lane-level accuracy and integrity. It also specifies the data sets to be contained in messages between the nomadic device and the control station providing GNSS correction and integrity information. This specification enables the nomadic device to support lane-level positioning and integrity monitoring. Enabling techniques and methods, which can be different for each provider or vendor, are not addressed in this document.
