Description (English):

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.

Abstract

Overview

ISO 22086-2:2024 defines the functional requirements and data sets for nomadic devices used with a network‑based precise positioning infrastructure for land transportation (NETPPI‑LT). Focused on lane‑level positioning and integrity monitoring, the standard specifies what nomadic devices must receive, monitor and compute to achieve GNSS‑based lane accuracy and to alert when positioning error exceeds an alert limit. It covers the required measurements, message content between nomadic devices and the control station, and the set of GNSS threats and errors to be detected, mitigated or removed.

Key technical topics and requirements

Nomadic device functions: reference network selection and request, fault detection and isolation (FDI), range correction and positioning, and protection level (PL) computation.
Required GNSS measurements: GNSS type, satellite PRN, pseudorange (code) and carrier‑phase measurements, navigation message, signal quality (C/N0 or SNR), lock time, and loss‑of‑lock indicators.
Data and messaging: definitions of message sets for requesting and receiving network and augmentation information, including correction information and integrity information exchanged between nomadic device (ND) and control station (CS).
Network modalities: support for on‑demand (unicasting) and broadcasting provisioning of corrections and integrity information over mobile and one‑way links (e.g., LTE, 5G, WAVE, DMB).
Integrity monitoring: identification of GNSS threats to monitor, error sources to remove or mitigate, and computation of protection levels to provide instantaneous upper bounds on positioning error.
Conformance with ITS models: aligns with the GNSS‑based positioning terminal model (EN 16803‑1) and the PoTi (position and time management) facilities layer (ETSI EN 302 890‑2).

Practical applications and users

ISO 22086‑2:2024 is intended for stakeholders building or integrating lane‑level positioning and integrity services:

Automotive OEMs and ADAS/autonomy suppliers implementing lane‑level navigation and safety functions.
Nomadic device and GNSS receiver manufacturers developing devices that consume NETPPI‑LT corrections and integrity messages.
Telematics and ITS service providers operating control stations and correction broadcast services.
Transportation authorities and system integrators deploying network RTK / NRTK services for road safety and traffic management.
Fleet management and logistics platforms requiring high‑integrity lane awareness.

Adoption enables reliable lane‑level positioning for use cases such as lane‑specific warnings, precise vehicle localization for cooperative driving, and safety‑critical ITS applications.
