POLARIS - Detailed Service Analysis (Galileo). Subtask 2: User Tools
Overview
Background & policy context:
Polaris is a software tool that will provide a link between the Galileo System design and users. Polaris analyses Navigation Performances and includes a graphing utility with an interface to an internal GIS application. Polaris is divided in five subsystems: the Graphical User Interface (GUI), a program core, the GIS subsystem, the GNSS subsystem and the user application subsystem. The GIS subsystem will provide users access to a GIS database. This database needs 3D maps. However nowadays 3D maps are very expensive and for the purpose of Polaris such realistic maps
are not necessary. In fact, this situation can be override by leaving the user create 3D maps from 2D realistic maps. Actually, the 3D Environments Tool shall be developed in order to create such 3D maps.
This SUM will help any user to effectively work with the 3D Environments Tool and to get a better knowledge of all the functionalities provided by the system.
Objectives:
Polaris
provides the means to demonstrate the benefits to be gained with a wide variety of combinations of systems and sensors in different user environments. Polaris has been designed to cope with different levels of user expertise. A non-expert user of the tool will be able to assess the performance of any combination of standard navigation devices in their particular operating environment. The navigation expert will also have the added advantage of being able to fine tune the individual components for a more rigorous analysis, particularly in terms of the GNSS and SBAS elements, thanks to Polaris’ advanced Graphical User Interface (GUI).
Methodology:
The major objective of this task is to provide models for ‘real-life’ navigation application environments. This includes trajectory modelling (assigning realistic position and velocity profiles for each application) and environment modelling (describing the impacts of signal obstruction, reflection and interference, etc). Details of these activities are documented in D4.4.2 “Characterisation of Applications”.
