|Abstract:||Connected and autonomous vehicles (CAV) utilize vehicle to anything (V2X) communication technology to transmit information between the vehicle itself and the intelligent entities (e.g. other vehicles, infrastructures, other road users, cloud servers, etc.). Dedicated short-range communication (DSRC), as a V2X implementation approach that is developed to support a variety of CAV applications, unfolds a new horizon for the vehicular world. With previous experiments, Network RTK (N-RTK) GNSS positioning suffered from wireless network performance and satellite visibility either separately or both at the same time. As for wireless network conditions in the UK, according to recent statistics, 12.7% of the UK territory could not receive 2G/3G signal from any telecom operator. Most of these “black spots” exist in places far away from city (e.g. highway, village). Moreover, wireless signal coverage provided by different telecom carriers varies significantly. In this paper, we evaluate the DSRC and its real-world performance under complex real-world testing scenarios. An innovative approach which utilizes DSRC to extend N-RTK coverage through collaborative positioning and navigation is presented. The work also covers the assessment to service otherness between each telecom carrier when working individually and their complementary performance when integrated with DSRC devices. The N-RTK availability improvement is analyzed. This work is partly funded by the Innovate UK, a governmental innovation agency, through its i-MOTORS project, one of the eight CAV1 projects awarded in 2016.|
