TACOT
Trusted multi-application receiver for trucks

Background & Objectives

GNSS systems are widely used in a multitude of applications around the world. This success is due to their global high-performance services. Nevertheless, these systems do have some drawbacks, as GNSS signals:

  • are unavailable or only partially available indoors or in masked environments;
  • can be subject to jamming, meaconing or spoofing.

These issues hinder / slow down the adoption of GNSS in applications which require high service availability or a good level of confidence in PVT information.

Why this project is important for EGNOS/GSA/SatNav?

TACOT will demonstrate that a GNSS based “trusted” PVT necessary to enable liability critical / legally binding applications can be achieved at relatively low cost thanks to EGNOS and Galileo.

Objectives

Trusted information will form the basis of numerous GNSS applications, in particular applications that are regulated, or those where legal liability is an issue. In this context, the overall objective of the TACOT project is to prepare for the introduction and promote the use of EGNOS and Galileo in the road transportation industry through the addition of a secure GNSS function to the Digital Tachographs (DT), providing reliable data to any ITS application.

The integration of the TACOT trusted GNSS function in existing ITS applications and services will directly benefit the road community. Indeed, this new function will allow the use of GNSS in applications requiring a minimum level of confidence in the PVT information. In the specific case of tachographs, this solution will notably offer the possibility to record start and end positions for truck journeys, as required by the regulations. This reliable function will also benefit other ITS domains (regulated or not) such as: PAYD, anti-theft systems and Fleet Management Systems. Furthermore, it shall also benefit industry by authorizing new applications and services using the trusted PVT at a relatively low cost.

How does it work?

See the pictures below.

Next Steps

The next steps will be to bring the trusted PVT module to the Digital Tachographs / ITS applications markets.

Work performed & results

TACOT will design a trusted GNSS module supplying PVT information with a confidence indicator. Basically this module will perform a smart merge of several sensors to analyse the consistency of information. TACOT will also modify the existing DT (digital tachograph) design to integrate this GNSS function.
To demonstrate the capability and interests of the trusted PVT function in the DT and for ITS applications, a prototype will be developed and tested on board trucks, with a Fleet Management System.
