DECIVEL: The IG wins Technology Transfer grant for R+D of kinematic determination of track and linear structures
DECIVEL aims at building a pre-commercial product together with the company Al-Top based in Barcelona. The product will integrate an existing track geometry measuring trolley with an advanced INS/GNSS trajectory determination system –the DECIVEL– based in the integration of the recent miniaturized electromechanical Inertial Measurement Unit (IMU) technology, GNSS carrierphase multiconstellation receivers and on research results of the Institute of Geomatics (IG).

The device is a [railway] kinematic high-precision track-geometry measuring and determination system that will boost the productivity of the existing trolley by replacing a static, expensive, time consuming surveying procedure by a kinematic, fast one. DECIVEL will be exported worldwide using the existing worldwide distribution network of Al-Top.

The fast, accurate and low-cost procedure introduced by DECIVEL contributes to the safety and quality of train transportation. Al-Top’s current trolley will be modified to host DECIVEL. DECIVEL includes an evolution of and leverages IG’s experimental mTAG prototype (data collection and synchronization Hardware & Software system) and NAVEGA (real-time and off-line time-Position-Velocity-Attitude INS/GNSS determination software). DECIVEL has been preceded by GeoTRAM, co-funded by the Spanish Ministry for Science and Innovation (MICINN), a project that validated the DECIVEL concept. DECIVEL is, from the technology point of view, a low-risk development project.

The project will be supported by the European Union's Development Funds through the Catalonian Autonomous Government's PROVA'T programme.
