Vehicles Cooperative Navigation Using GNSS for Coordinates and DSRC for Mutual Heading

Cooperative navigation is a promising set of approaches for increasing the accuracy of navigating of vehicles as well as road safety in difficult environment such as urban canyons. DSRC (Dedicated Short-Range communication) is the radio-communication standard for vehicles. Usually cooperative navigation is based on sharing GNSS and other primary sensors measurements between nearby vehicles via DSRC (or other telecom systems such as 3G/4G). In addition to communication, the on-board IEEE 802.11p DSRC receiver allows to measure the angle between vehicle’s building axes and direction of received signal (from nearby vehicle). DSRC signals could share GNSS measurements and mutual headings of other surrounding vehicles. On-board fusing of surrounding vehicles’ coordinate and corresponding heading angles measurements leads to increasing of navigating accuracy. Here the possible effect of proposed approach is estimated. (Abstract)
