Full title and description

Space systems — Space-based services for a high accuracy positioning system with safety requirements. This Technical Specification defines system-level requirements and recommendations for space‑based systems that, using satellite radionavigation services, provide high‑accuracy positioning of rovers where specific safety requirements apply (including low‑visibility operations).

Abstract

This document provides requirements and recommendations for space‑based systems that, by using satellite radionavigation services, deliver high‑accuracy positioning for rovers with safety needs. It includes methods to verify the system requirements and complementary information on particular applications (Annex A), mobile mapping systems (Annex B) and augmented positioning (Annexes C and D).

Scope

ISO/TS 22591:2021 sets out system requirements and recommended practices for space‑based services that enable high‑accuracy positioning of rovers using satellite radionavigation. The scope targets rover applications that have safety‑critical performance needs (for example, operation in low‑visibility conditions) and specifies verification methods for the system‑level requirements; annexes provide application notes for specific use cases, mobile mapping and augmentation techniques.

Key topics and requirements

• System‑level performance requirements for high‑accuracy positioning (accuracy, availability, continuity and integrity considerations for rover operations).
• Safety requirements and recommendations for rover operation in constrained or low‑visibility environments.
• Verification and validation methods to confirm system conformance with the specified requirements.
• Guidance on use of satellite radionavigation services and augmentation techniques to meet high‑accuracy and safety objectives (covered in annexes).
• Application notes addressing particular use cases and mobile mapping system considerations.

Typical use and users

Primary users include space system designers and integrators, satellite navigation service providers, developers of rover and autonomous ground vehicles, teams responsible for safety and certification of high‑accuracy positioning systems, research organizations working on space‑based navigation, and national/regional standards bodies referencing technical rules for rover positioning and safety verification.

Related standards

Related work is produced by ISO/TC 20/SC 14 (Space systems and operations). Relevant complementary standards and documents include other ISO space‑systems publications on positioning and system verification, plus GNSS and augmentation system standards from international navigation bodies; ISO/TS 22591 is also being followed by a committee draft (ISO/CD 22591) intended to update/replace the TS.
