Full title and description

ISO 24246:2022 — Space systems — Requirements for global navigation satellite system (GNSS) positioning augmentation centres. This standard specifies requirements for GNSS positioning augmentation centres that distribute correction data and integrity information to deliver higher-accuracy and higher-integrity positioning services for civil and commercial users.

Abstract

This document defines functional and technical requirements for GNSS positioning augmentation centres, covering real-time sub‑meter to decimetre‑level positioning, real‑time centimetre‑level positioning and post‑processed geodetic positioning. It also specifies stakeholder roles (planner, designer, administrator) and required software functions for augmentation‑centre operation.

Scope

ISO 24246:2022 applies to GNSS positioning augmentation centres that produce and distribute correction and integrity data for different service classes: (a) real‑time sub‑metre to decimetre positioning, (b) real‑time centimetre‑level positioning, and (c) post‑processed geodetic positioning. The standard covers roles and responsibilities (planner, designer, administrator) and the principal software functions required to operate augmentation centres.

Key topics and requirements

• Defined performance classes for positioning accuracy and integrity (sub‑metre/decimetre, centimetre, geodetic post‑processing).
• Requirements for distribution of correction data and integrity information to users (real‑time and post‑processing modes).
• Clear assignment of stakeholder roles and responsibilities: planner, designer, administrator.
• Specified software functions and operational capabilities required at augmentation centres (monitoring, generation and dissemination of corrections, integrity monitoring).
• Interfaces and message/format considerations (typical deployments rely on established correction message formats and distribution protocols such as RTCM and IGS/RTS products — noted here as commonly used complements to the ISO requirements).
• Performance monitoring, service assurance and operational procedures to ensure maintained accuracy and integrity (inferred from the standard’s emphasis on defined accuracy/integrity classes and software functions).

Typical use and users

Primary users include GNSS augmentation‑service providers and operators of positioning augmentation centres, system and software designers for GNSS infrastructures, satellite and space‑system engineers, national metrology and surveying organisations, geodetic service providers, and regulatory bodies overseeing GNSS‑based services. (User list is a summary interpretation based on the standard’s scope and intended service classes.)

Related standards

Standards and specifications commonly referenced or used alongside ISO 24246 include RTCM correction message standards and IGS real‑time and post‑processing product specifications (for precise orbits, clocks and other products used by augmentation centres). ISO 24246 is developed under ISO/TC 20/SC 14 (space systems), so related ISO space‑system standards from the same technical committee may also be relevant.

FAQ

Q: What is this standard?

A: ISO 24246:2022 is an international standard that sets requirements for GNSS positioning augmentation centres — the facilities that generate and distribute correction and integrity data to improve positioning accuracy for civil and commercial users.

Q: What does it cover?

A: It covers functional and technical requirements for augmentation centres supporting three service types: real‑time sub‑metre to decimetre positioning, real‑time centimetre‑level positioning, and post‑processed geodetic positioning; and it specifies stakeholder roles and required software functions.

Q: Who typically uses it?

A: Operators of GNSS augmentation services, GNSS system integrators and designers, geodetic and surveying organisations, and regulators or certification bodies that assess augmentation‑service performance. This is a practical summary derived from the standard’s scope and target service classes.

Q: Is it current or superseded?

A: ISO 24246:2022 was published in June 2022 and is the current published edition (Edition 1). The ISO entry shows the document as published and subject to ISO life‑cycle review processes. Users should check ISO or their national standards body for any amendments or revisions after 2022.

Q: Is it part of a series?

A: It is an ISO standard produced under ISO/TC 20/SC 14 (space systems). While not identified as a numbered "series" in the title, it is related to other space‑system and GNSS‑related standards and is commonly used alongside correction/message specifications such as RTCM and IGS product specifications.

Q: What are the key keywords?

A: GNSS, augmentation, augmentation centre, corrections, integrity, real‑time positioning, centimetre‑level, post‑processing, RTCM, IGS.
