Overview
The general objective of the ERSEC project is concerned with the broadening of the scope of application to road transport of the EGNOS/GNSS (and later Galileo) through an appropriate integration and data fusion with measurement data coming from other measuring instruments. More specifically, the S&T objective of the project is to develop a measuring system - to be used on board of vehicles - able to output the position on the road map of the equipped vehicle and of all the obstacles (such as other vehicles, peoples and any kind of fixed or mobile objects) around it with a measurement accuracy of the order of 0.1 metre at a sampling rate of 100 Hz.
The proposed approach is based on an intelligent data fusion of the EGNOS/GNSS sensor positioning measurement, the Road-GIS digital local map data and the measurement data obtained from an instrument set installed on board of the vehicle, including vehicle dynamic sensors and environmental sensors. Beside the hybridization with other sensors, the optimal use of EGNOS (and Galileo in the future) key differentiators (accuracy, integrity) will be a key factor for the success of the project. This challenging target is required to open the possibility to apply the above positioning data to improve the performance of active road safety systems aimed to avoid collision and off road accidents. Furthermore, ERSEC will open new business opportunities for European companies besides collision avoidance applications, resulting in highly accurate and reliable positioning. The scope of the ERSEC project covers the study and development of a prototype of the ERSEC measuring system and two demonstrators. A vehicle will be equipped with the ERSEC prototype measuring system and a set of trials performed. Furthermore, the ERSEC prototype system will be integrated in a vehicle equipped with a Collision Avoidance System and trials will be performed in order to evaluate the positive impacts on road safety of the EGNOS-GNSS data availability.
