Autonomous vehicles synchronization uses nanosecond level and PTP IEEE1588 profile AES67/IEEE 802.1AS. Vehicle platooning is part of a suite of features that autonomous cars might employ. A platoon is a group of vehicles that can travel very closely together, safely and at the high speed. Each vehicle communicates wireless with the other vehicles in the platoon. Beside, synchronisation is essencial for autonomous AI driven vehicles. It creates alternative to GNSS positioning system – the one that basis on multiple lidar sensors and object recognition. Such synchronized solutions are resistant for GNSS jamming/spoofing attack. Elproma NTS-pico3 is leading product on autonomous vehicle market today.
