Here, the data logger as gPTP master regularly sends its internal timestamp to all connected gPTP slaves, which use this information to correct their internal timestamps. In this way, all parts of the logging system are put on a common time base and discrepancies due to runtime differences are eliminated. Possible differences between the timers of the individual capture modules and the data logger are also dynamically corrected. This ensures that all vehicle buses, LVDS adapters such as camera, LiDAR or radar sensors connected to the data logger are recorded in a correspondingly synchronized manner.
All incoming data now has the exact same time stamps, which makes it extremely easy for the development departments to process and analyze the recorded data.
