Name: IMU & GNSS VEHICLE ODOMETRY
Object: Development of a new odometric sensor based on a GNSS receiver and an inertial platform (IMU)
The IGLOO project aims at developing a new odometric sensor based on a GNSS receiver, a 6-axis inertial measurement unit (IMU) and a dynamic model of the train, capable of delivering a speed based on information from navigation satellites. This sensor will have to be integrated into an on-board subsystem ERTMS (European Rail Traffic Management System). The performance of the sensor will be validated through comprehensive testing under real operational conditions.
Currently, M3 Systems is developing a data collection tool, MultiPDR, which will be used to record data from various inertial units, as well as GNSS signals. Long-term data collection on trains is planned for the end of 2019. These will be used to:
