GREET

This activity aims to develop a GNSS receiver platform for rail (the GREET Receiver Platform), which will help realize the important potential of GNSS as a component of the on-board multi-sensor train localization unit (TLOBU). Fusion with other sensors (e.g. Inertial Measurement Unit (IMU), tachometer, track geometry, etc.) will be mandatory to mitigate the known impact of local effects on GNSS performance and allow the use of a localization unit, with the required safety level, across all the European rail network, from main lines to regional lines, from mountainous areas to urban environments.

The following key features are for seen for the GREET receiver platform:
- Capability to provide the positioning solution with the input from the GNSS sensor, inertial sensors, and route information.
- Capability to continuously monitor the signal and measurement quality.
- Capability to provide the integrity, availability and accuracy of the system.
