GNSS Signal Quality Evaluation in Finland. Preliminary Study

Abstract

This is the Final Report describing the GNSS-Signal Quality Evaluation in Finland (GLAS) –Preliminary Study project implementation. The project duration was from 1st October, 2016 – 28th February, 2017 and included identification of end-users, user requirements, initial service definition, and proof-of-concept demonstrator. This report also briefly describes the project structure and the future project plan. Section 1, 2, and 3 are an introduction to this document and the GLAS project. It describes the project scope and schedule for the first phase of activity, including a brief discussion about future phases of the project. Section 4 presents an executive summary of the report covering the most significant conclusions from this study. Section 5 lists the end-user groups and example end-users identified in the stakeholder analysis. This list was essential for inviting respondents to the project web-survey. Section 6 describes the results and conclusions of this web-survey – indicating the expectations and requirements of end-users. The complete web-survey results are provided in Appendix 3. Section 7 describes the conclusions from the detailed in-person interviews conducted with 4 (expert) end-users to know better their expectations and opinions. The detailed transcripts of the interviews are presented in Appendix 1. Section 8 presents conclusions from the comparative study of state-of-the-art services similar to GLAS-service available globally. The comparative table is provided in Appendix 2. Section 9 describes the FinnRef reference GNSS network and its capabilities, because that is envisaged as one of the data sources for the proposed service. Section 10 compiles all the information from previous Sections to offer an initial service definition for the GLAS-service based on which the first roll-out version of the service will be implemented. Finally, Section 11 describes briefly the proof-of-concept demonstrator service implemented as a prototype of the proposed GLAS-service
