IRONMAN Puts Draft Zones to the Test With Race Ranger and Aero Expert Marc Graveline

Precision: The core technology uses UWB for ultra-precision within 30 meters, providing accuracy within 10cm.
Update Frequency: Measurements are taken and displayed up to 8-10 times per second, ensuring up-to-date information for riders.
Technology Integration: The system transitions from GPS for initial athlete detection to UWB for the critical, high-precision distance measurement when athletes are close.
Latency: Years of research have focused on minimizing the delay (latency) between a rider crossing a threshold and the light signal changing, making it imperceptible.

For what it’s worth, they claim accuracy within 10cm (4”) in the 0 to 30 meter distance and ~ 10 updates per second. If that’s the actual case, it seems more than fit for the task to me.
