D2.2 HELMET CONOPS

This document is the deliverable D2.2 HELMET CONOPS which describes Concept of Operations (CONOPS) for HELMET (High integrity EGNSS Layer for Multimodal Eco-friendly Transportation) solution from viewpoint of high-accuracy and high-integrity EGNSS applications in rail (RAIL) and automotive (AUTO) sectors. The HELMET solution is mainly focused on ERTMS and automated car driving and supported by Unmanned Aerial Vehicles and Systems (UAV, UAS) in terms of infrastructure inspection, infrastructure assets monitoring, traffic management, etc. The main HELMET objectives are: 1) to develop a cyber-secured multimodal, multi-sensor integrity monitoring architecture based on EGNSS to introduce High Integrity Location Determination System (LDS) for trains, automobiles and Unmanned Aerial Systems (UAS/RPAS) automation with the later aggregating the demand of IMTM (Inspection, Monitoring and Traffic Management) for rail and road assets and operations, 2) to assess the system performance by a Proof-of-Concept (PoC), and finally 3) to draw a roadmap for exploitation and future standardization and certification of HELMET results in terms of (a) the designed multi-modal augmentation and integrity monitoring architecture, and (b) high integrity and accuracy OBU algorithms fully customized for land transportation (rail and road) and supporting aerial operations. The HELMET CONOPS is used as a starting point for specification and justification of high-level user requirements for RAIL, AUTO and UAV user groups. The purpose of the HELMET CONOPS is to describe the operational needs, views, visions and expectations of the user’s groups without provision of technical details on HELMET. The CONPOS is written in user language and generally represents a set of user requirements. It means that the high-level user requirements specified in the deliverable D2.1 (User Requirements Specification) have been extracted from this deliverable. The HELMET CONOPS also defines high-level performance requirements, objectives and other HELMET rationales. It is a high-level (user) requirements document whose intention is to provide mechanisms for HELMET users to describe their expectations from HELMET solutions. The HELMET CONOPS deliverable includes: • Identification of different operational modes/ scenarios for RAIL, AUTO and UAVs applications; • Identification of various operational environments and constrains; • Derivation of High-level User Requirements for HELMET solutions; • Summary of High-level User Requirements for HELMET; • Description of High-level safety concepts; • Derivation of High-level safety requirements; • Overview of High-level User safety requirements; • Regulatory requirements for certification and authorization process. The HELMET CONOPS serves as a basis for specification of high-level functional and system requirements (to be done in D2.3) and related technical specifications. Further, user needs and performance measures identified in the CONOPS are the fundamental information for the HELMET Requirements Traceability Matrix and Validation Plan elaboration to be used to validate the HELMET concept at the end of its development phase. The overview of the regulatory requirements for certification and authorization process in the given application areas will be utilised for standardization activities of HELMET solutions to be performed within WP6.
