Details of this Thursday’s Connected Car webinar emerged as speakers gathered today to share their presentation materials. (You can join this free webinar here.) A key concept is that no single technology can provide the required position accuracy in all environments. A combination of core GNSS technologies is needed: SSR-RTK with correction data (satellite and LTE), multi-GNSS for large number of measurements, Multi-band reception for minimal convergence time and 3D automotive dead reckoning.

The webinar is sponsored by u-blox.

Speakers from Renesas Electronics, Toyota InfoTechnology, u-blox and Denso will present technical material of interest to engineers and system integrators as well as product managers, strategic planners and executives.

The topics covered in the webinar include:

• Recent developments in – and the potential safety impact of – V2X technology, by Chaminda Basnyake, Renesas Electronics

Driver and Pedestrian intent are both expressed Over-the-Air (OTA). Key: Basic Safety Messages (BSM) / Personal Safety Messages (PSM) / Signal Phase and Timing (SPAT). OTA also broadcasts an intersection map and GPS corrections.

• The status of V2X standards (traditional DSRC and emerging 3GPP), and the status of US spectrum and NHTSA regulations, by John Kenney, Toyota InfoTechnology Center

Spectrum choices and the possibility of unlicensed device spectrum sharing.
