Geodetic Kinematic Terrestrial Navigation using a MMS – Multi-constellation and multi-frequency Galileo/GPS/GLONASS performance comparisons

This paper presents a part of the research activities performed from 2019 to 2022 in the framework of WP 5.3 “Field campaign” and in particular, the activities “Land urban and extra-urban data measurement campaigns” of the European GRC-MS (Galileo Reference Center – Member States) Project - GSA/GRANT/04/2016. The dynamic data-collection campaigns were conducted by three participating member states (Portugal, Italy, and Romania), in three different environments: aerial, terrestrial, and maritime, respectively. This article presents a comparison of the results obtained for the terrestrial environment, considering the performance of Galileo used in conjunction with other GNSS systems, such as GPS, using different geodetic and navigational multi-constellation and multifrequency receivers/devices experimental dynamic activities. Starting from the user’s needs and requirements, the experimental setup and the methodology for the estimation of the reference («actual») trajectory are provided. These are complemented by numerical results and reasons for possible performance degradations analyses. The processed rover trajectories and the produced outputs were compared to the reference trajectory obtained from GNSS/INS (INertial System) integrated high-performance solution. Galileo-only and GPS-only solutions, so as multi-system solutions (GPS+Galileo, GPS+GLONASS and GPS+GLONASS+Galileo) were analysed. PVT (Position Velocity Time) solutions were computed using post-processing geodetic interferential techniques. From the performed analyses, some preliminary conclusions relative to the Galileo performances applied to terrestrial urban and extraurban navigation were derived. These activities need to be continued in the near future, taking into consideration the Galileo constellation improvements and the ITS (Intelligent Transport Systems) applications in order to improve the offered services and the road safety

Improve information provision for disaster management: MONITOR II, EU project

Management of natural hazards constitutes a common challenge in all country of the world. Until now, neither hazard mapping nor contingency planning have been transnationally coordinated and defined. These gaps will be tackled in MonitorII project (founded by the EU - South East Transnational Cooperation Program) with the development of a common methodology about risk assessment and risk management. The project partnership has so far carried out the following activities and achieved the following results: review of best practices in hazard mapping and contingency plans; definition of information needs and information flows in different phases of risk management; definition of novel concepts for the creation of simplified scenario models in the process, damage and intervention domain. In the project will be developed a Continuous Situation Awareness system, a software that support the disaster management in the different phases of the risk cycle. Within the broad range of hazards, MonitorII specifically deals with floods and landslides, but the concepts of the project could be applied to other types of hazards

Monitor II: new methods for linking hazard mapping and contingency planning

The present brochure deals with the state of the art of hazard mapping and contingency planning and provides a general framework for adaptations and improvements. This brochure is intended to provide information to • experts of hazard mapping and natural hazards • authorities competent for disaster management, esp. contingency planning. The goal of the brochure is to provide these groups with a better understanding of the tasks and needs of each other. The long term goal is to improve communication between these domain expert groups. As state-of-the-art analysis, this brochure reflects the discussion arising from the problems and issues encountered by the participating project partners in their testbeds
