Arctic Region Space Weather Customers and Space Situational Awareness Services Per Høeg, Kirsti Kauristi, Peter Wintoft, Magnus Wik, Claudia Borries

Objectives Identify how the ESA Space Situational Awareness Programme (SSA) Space Weather customer requirements need to be enhanced and tailored for the end-users in the Arctic region, and describe how these requirements can be fulfilled. Approach: Assessing the services in the four Expert Service Centres (ESC) and combining this knowledge with an user-survey. Clarifying how the products of the four Expert Service Centres (ESC) in the ESA Space Situational Awareness Programme (SSA) contribute to the requirements of SSA services for the Arctic. Clarifying how new products and services for the Arctic region need to be developed and implemented. Identifying end-user requirements and needs in public and commercial sectors, active in the Artic regions, through user-surveys and the interviews with key-companies. Analyse and map the survey results to the present SWE system and products. Suggest a roadmap for the development of future Arctic region SSA services.

Tailoring ESA Expert Service Centres (SWE) Services for the Arctic Regions Approach: Three SWE documents and databases perform the basis for the study: 1.Customer Requirement Document (CRD) 2.Product Specification Document (PSD) 3.System Requirement Document (SRD) 3

Tailoring ESA Expert Service Centres (SWE) Services for the Arctic Regions The Customer Requirement Document (CRD) identifies eight SWE service domains and end user groups: 1.Spacecraft design (SCD): Personnel involved in generating space environment specifications for the design of spacecraft. 2.Spacecraft operation (SCO): Flight Control Teams, operations support engineers, and science operations centre teams of European and national space agencies, public and private spacecraft operators. 3.Human space flight (SCH): The operation teams of human spaceflight including during launch, activities inside and outside of the ISS, future space tourism flight operators and future human missions in outer space. It is anticipated that they will be represented by space agencies and European entities operating sub-orbital or orbital flights for space tourists, e.g. EADS-ST, Virgin Galactic. 4.Launch operation (LAU): Personnel involved in launch operation. It is anticipated that they will be represented by space agencies and European entities operating launchers, e.g. Arianespace, EADS-ST, Virgin Galactic. 5.Transionospheric radio link (TIO): Service users from space-based systems using electromagnetic waves propagating through the ionosphere and for which service performance may be affected by ionosphere disturbances due to space weather events. The main users are GNSS but also some satellite communication and earth observation services are included. 6.SSA Space Surveillance and Tracking (SST): Personnel involved in the Space Surveillance and Tracking segment of the SSA system. This is therefore a space weather service internal to SSA. 7.Non-space systems operation (NSO): Such as pipeline, power grid operators, surveying industry, airlines. 8.General data service (GEN): Expert users in the space industry, third party service providers in a range of domains, the education sector and the general public (including amateur radio/disaster monitoring- communication) 4
