Abstract
A system for measuring the position of one or more object in an area of interest. The system has an ultra wideband position measurement system with a plurality of beacons which are each located in separate fixed positions with respect to the area of interest; and one or more portable tag which is attachable to the object and a Global Navigation Satellite System (GNSS). The portable tag has an ultrawideband receiver which receives UWB data for determining the UWB position of the portable tag with reference to the primary and secondary beacons, a GNSS receiver which receives GNSS data for determining the GNSS position of the portable tag with reference to GNSS system satellites, a kinematics module which creates kinematic data to determine movement of the tag based upon kinematic changes in the tag, a processor which comprises, a data augmentation module which calculates position data which represents the most accurate position for the portable tag based upon the UWB position, the GNSS position and the movement of the tag as calculated by the kinematics module.
