SP3 - SINTECH

SP3

The objective of the SINTECH sub-project was to analyse, adapt and enhance communication technologies in order to properly integrate them into the vehicle and infrastructure platforms. Prototypes mainly existed as software implementations and were fed into SAFEPROBE and INFRASENS activities, where such software modules were integrated into the vehicle and infrastructure prototypal platforms.

Main technologies considered in SINTECH were:

  • Co-operative relative localisation: highly accurate and reliable localisation system; Reliable, very accurate, real-time relative positioning
  • GNSS-based Positioning (GPS, Galileo)
  • Communication-based Positioning (UWB, WLAN)
  • Image-based Positioning (Landmarks recognition)
  • Local temporary vehicle maps for safety applications

  • Ad hoc dynamic vehicle-vehicle-infrastructure network; in order to exchange time-critical, safety related information this requires:
    • Reliable, fast, secure, potentially low cost protocols for local V2V and V2I communication
    • Routing protocols with multi-hop forwarding and geo-cast functionalities Geographical addressing
    • Channel control (multi channel operation, power control, data rate selection)
    • Priority access

The communication technology used was IEEE 802.11p. With the ECC Decision of 14 March 2008 on the harmonised use of the 5875-5925 MHz frequency band for ITS a dedicated frequency band for safety related V2V and V2I communications has been made available.
