A range error reduction technique for positioning applications in sports
Abstract In recent times, ultra‐wideband (UWB)‐based positioning systems have become popular in sport performance monitoring. UWB positioning system uses time of arrival to calculate the range data between devices (i.e. anchors, tags), and then use trilateration algorithms to estimate position coord...
