Standards List

This document specifies contents and formats of positioning information that is exchanged between appliances, features, and systems in motion or at rest, for safety, reliability and resilience of navigation. It is applied to onshore, maritime and aerial applications using space-based positioning and other sensing.

This document specifies architectural basis of space-based positioning, navigation and timing (PNT) services for civil land, maritime and aerial applications using a global navigation satellite system (GNSS).

This document provides requirements and recommendation for space-based systems that, using satellite radionavigation services, provide high accuracy positioning of rovers. It is particularly intended for rovers whose operation requires meeting specific safety requirements, including in situations of low visibility. This document also provides methods to verify the system requirements, as well as complementary information on particular applications (Annex A), mobile mapping systems (Annex B) and augmented positioning (Annexes C and D).

This standard applies to road vehicles. For a set of scenarios, a minimum set of assumptions regarding reasonably foreseeable behaviors of other road users are defined that shall be considered in the development of safety-related models for automated driving systems (ADS). This standard further defines a list of attributes common to contributed safety-related models and methods to help verify whether a safety-related model takes the minimum set of assumptions into consideration. An informative annex instantiates several examples of how the proposed minimum set of assumptions could be employed in ADS development. Sources of uncertainty, such as prediction or perception errors, are out of scope to this standard. This standard does not guarantee the safety of the overall system in all scenarios.

The goals and metrics of a data storage system for automated driving (DSSAD) are defined in this standard. Functions and common technical requirements for data storage are identified. Data elements relevant to automated driving system (ADS) Level 3, Level 4 and Level 5 are defined. The usage of data among diverse end users is also defined. A compendium of data elements used in vehicles of categories M1 and N1 regarding their EDR and DSSAD for partial and fully automated vehicles is provided in this standard. An on-board diagnostic (OBD) port lockout/near field communication (NFC) protocol for protection against data manipulation via the vehicle diagnostic port is provided. This standard is made available without prejudice to national and regional laws related to data privacy, protection, and personal data processing. Users are responsible for compliance with all such laws and regulations. This standard may be frequently updated to include relevant data definitions and data elements toward the development of automated vehicles. The overall goal is to create a data collection standard for automated driving that includes functional requirements for automated vehicle gateways and security guidelines for cloud-based automotive data recorder requirements.

This document delineates the performance, functional, interface, and environmental parameters for Differential GPS (DGPS) reference stations, integrity monitors and Transmitter/RSIM interface modules. The intent of this document is to facilitate both the manufacture and the purchase of service provider equipment in order to make the use of DGPS more economical and deployable through standardization. It will encourage consistency from one service provider to the next and thereby facilitate the use of DGPS.
This document is specific to the maritime area only in that the data link modulation specifications and certain control parameters are given for Minimum Shift Keying (MSK) Modulation in the Medium Frequency (MF) band in which Marine Radiobeacons operate. Otherwise, this document is readily applicable to many other DGPS applications including terrestrial and satellite links.
Performance parameters are defined in order to establish common terms of reference for evaluation, comparison, and certification. Where appropriate, minimum performance levels are specified; otherwise, minimum performance depends on the requirements for the specific application, and will be published in the service provider's broadcast standard.
A set of Reference Station/Integrity Monitor (RSIM) Messages is defined in order to standardize equipment interface parameters and to facilitate the flow of information between the various equipment (Reference Station, Integrity Monitor, Transmitter/RSIM Interface Module, and Control Station) regardless of the manufacturer. Within this specification, RTCM Recommended Standards For Differential NAVSTAR GPS Service pseudorange correction and ancillary messages are denoted as RTCM messages, and RTCM SC104 RSIM messages are denoted as RSIM messages. Type 1 RTCM messages are denoted RTCM No. 1, and Type 1 RSIM messages are denoted RSIM No. 1.

Networked Transport of RTCM via Internet Protocol (Ntrip) is an application-level protocol that supports streaming Global Navigation Satellite System (GNSS) data over the Internet. Ntrip is a generic, stateless protocol based on the Hypertext Transfer Protocol HTTP/1.1. The HTTP objects are extended to GNSS data streams.
Ntrip is designed to disseminate differential correction data or other kinds of GNSS streaming data to stationary or mobile users over the Internet, allowing simultaneous PC, Laptop, PDA, or receiver connections to a broadcasting host. Ntrip supports wireless Internet access through Mobile IP Networks like GSM, GPRS, EDGE, or UMTS.
Ntrip consists of three system software components: NtripClients, NtripServers and NtripCasters. The NtripCaster is the actual HTTP server program, while NtripClient and NtripServer act as HTTP clients.
Ntrip is meant to be an open non-proprietary protocol. Major characteristics of Ntrip???s dissemination technique are the following:
It is based on the popular HTTP streaming standard; it is comparatively easy to implement when limited client and server platform resources are available.Its application is not limited to one particular plain or coded stream content; it has the ability to distribute any kind of GNSS data.It has the potential to support mass usage; it can disseminate hundreds of streams simultaneously for up to a thousand users when applying modified Internet Radio broadcasting software.Regarding security needs, stream providers and users are not necessarily in direct contact, and streams are usually not blocked by firewalls or proxy servers protecting Local Area Networks.It enables streaming over any mobile IP network because it uses TCP/IP.

The scope of this standard is a generalized autonomous system standard framework using light autonomous road vehicles as a concrete example. To that end, this version of the standard includes extensive prompt lists applicable to light autonomous road vehicles (both passenger and cargo vehicles). Many of the prompts will apply to other autonomous ground vehicles and even other types of autonomous systems, but no specific attempt has been made to include extensive prompts for other applications, nor to segregate road vehicle prompts from more general prompts.

The present document captures the findings of the study item, 'Study on channel model for frequency spectrum above 6 GHz' [2]. The purpose of this TR is to help TSG RAN WG1 to properly model and evaluate the performance of physical layer techniques using the above-6GHz channel model(s).
This document relates to the 3GPP evaluation methodology and covers the modelling of the physical layer of both Mobile Equipment and Access Network of 3GPP systems.
This document is intended to capture the channel model(s) for frequencies above 6 GHz up to 100GHz.
