Joint Galileo Optimization and VANET Enhancement

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

In GLOVE, solutions integrating GNSS and VANETs are studied: they may play a key-role in providing a competitive advantage in the field of GNSS receivers and integrated Navigation Platforms.


The integration of GNSS and the WAVE transceiver is a key enabler for VANET services, but has not been standardized. The simplest solution is that the GNSS receiver feeds both the navigator and the WAVE transceiver with the time-position information required. This architecture is intuitive but it is too rigid to deliver new services.
Even more VANETs show weaknesses (scalability, hidden terminals) that could be improved with time and position information, as available from GNSS.


GLOVE investigates the mutual benefits coming from the cross-domain integration between (i) Galileo/EGNOS GNSS (Global Navigation Satellite System) and (ii) VANETs (Vehicular Ad-Hoc Networks).
Such integration is already foreseen on vehicular On-Board Units (OBU), but has not been extensively studied to exploit all the potential benefits of a closer coupling between the two domains.
GLOVE proposes to cover this area, in strong synergy with other research projects. The problem is split into three steps, corresponding to the functional blocks constituting the overall GLOVE OBU:

  • a GNSS receiver (OBUg) also integrating information other than GNSS signals (e.g. from the VANET domain);
  • a VANET transceiver/router (OBUv) benefiting as much as possible from both time and space information;
  • a block (OBU^) performing the integration between Galileo/EGNOS and VANET data, expected to improve existing vehicular services and to enable new ones.
How does it work?: 

It works as follows:

a) The information about position coming from the GNSS receiver is merged with additional information (mutual position from VANETs, on-board sensors, position on the map).
b) VANETs can better multiplex their transmissions, exploiting universal time-space coordinates as available from GNSS (e.g. for better channel access and efficient forwarding).
c) New services are integrated in the navigator (e.g. VANET-aware routing and visualization).


Expected results of the project include both theoretical (architectures, performance evaluations, analysis of weaknesses and points of strength of the envisioned solutions) and practical ones (demonstration of the solutions and of the related services).
Both of them have a scientific relevance, as explained within Annex B, thus adhering to the topic Galileo.2011.1.3-1.
The results are also expected to:

  • overcome some current weaknesses of VANETs, leveraging the GNSS signal
  • improve Galileo positioning, leveraging VANET
  • widen the Galileo potential, improving and widening the set of on-board services to the driver.

In particular, practically demonstrable results and prototyping have been enforced during the negotiation phase.

Next Steps: 

The Consortium will keep ETSI informed about the results achieved in order to facilitate the exploitation of results (concerning VANETs).
