The Validity and Reliability of Global Positioning Systems in Team Sport: A Brief Review. (2016, background): “(35) found when using 10Hz GPS devices to measure instantaneous velocities during running that all noise values (CV) were much smaller than the signal values (SWC), indicating that 10Hz GPS devices are sensitive enough to detect all physiologically significant changes in velocities.”
Global Positioning Systems (GPS) and Microtechnology Sensors in Team Sports: A Systematic Review (2013, methodology): “The gold standard criterion method used to investigate GPS validity for distance is to measure a course with a trundle wheel or tape measure and, for speed, use of timing gates at the start and finish [9] or a speed gun [10].”
Training Load Monitoring in Team Sports: A Novel Framework Separating Physiological and Biomechanical Load-Adaptation Pathways (2017, background): “the fact that reliability and validity of velocity-based measures is lower for movements with higher accelerations [10, 17], and the accuracy of GPS-based acceleration signals is known to be limited [18].”
Peak speed determination in football: is sprint testing necessary? (2018, methodology): “…showed a large association with timing gates during a 40-m sprint assessment, and the typical bias was trivial, corroborates previous work (Varley et al. 2012; Roe et al. 2016) and supports the notion that 10 Hz GPS is a valid proxy for timing gates (acknowledging that higher-resolution…”
