Developed by ITS Chrono, the ATLAS FLASH module is a new-generation on-board GPS beacon combining high-precision real-time tracking with dynamic flag signaling directly to the driver. Designed to meet the requirements of professional automotive and motorcycle competitions, ATLAS FLASH establishes a direct and instantaneous link between Race Control and each vehicle, significantly improving safety, responsiveness, and operational control. Based on a high-frequency multi-constellation GNSS architecture and robust 2.4 GHz radio communication, ATLAS FLASH ensures reliable and ultra-fast data transmission, even in the most demanding environments. ATLAS FLASH integrates natively into the ITS ATLAS ecosystem, providing a complete and coherent solution for safety management and real-time tracking.
