Unlike alternative VoD systems that require annual calibration due to analogue drift, ShotTrack units use a high-precision digital timer chip that does not drift over time. We verify this timer against GPS timestamps by measuring the number of samples in exactly one second with 50 ns RMS accuracy. This consistently gives us timing accuracy of around 99.997%.
The only calibration needed is for the coaxial cable, which is easily set in the app. As long as the correct cable factor is applied, there is no need for ongoing recalibration. This is a key advantage of our system, offering greater reliability, less downtime, and no hidden maintenance costs.
