Abstract Over the last century numerous techniques have been developed to analyze the movement of humans while walking and running. The combined use of kinematics and kinetics methods mainly based on high speed video analysis and forceplate have permitted a comprehensive description of locomotion process in terms of energetics and biomechanics. While the different phases of a single gait cycle are well understood there is an increasing interest to know how the neuro-motor system controls gait form stride to stride. Indeed it was observed that neurodegenerative diseases and aging could impact gait stability and gait parameters steadiness. From both clinical and fundamental research perspectives there is therefore a need to develop techniques to accurately track gait parameters stride-by-stride over a long period with minimal constraints to patients. In this context high accuracy satellite positioning can provide an alternative tool to monitor outdoor walking. Indeed the high-end GPS receivers provide centimeter accuracy positioning with 5-20 Hz sampling rate .
