low cost Real Time Kinematic) and continuous/discrete augmentation sensors

The flexible design will enable future sensor enhancements to GPS/GNSS (e.g. A Localisation Component was developed based on a hybrid data fusion approach utilising low-cost GPS receivers augmented by electronic fences and a map model to significantly improve worker to work site zone mapping.The Mobile Terminal architecture is organised in different layers: Mobile Terminal (MT), fully based mainly on standard (COTS) hardware components and designed to become labelled as a Safety Integrity Level 2 (SIL 2 according to CENELEC railway standards). The core components and innovative characteristics of the ALARP project were made up of the following features: This in turn will result in the hazard rate being reduced and the false alarm rate being lowered. The utilised methods will result in an enhanced Train Presence Alert Device, enjoying an improved and high detection rate. The main achieved results of the ALARP project can be summarised as the viability of overall system approach, the integration of the main expected features and the validation of the selected technical solution.
