Abstract: A system for measuring the position of one or more object in an area of interest. The system has one or more portable tag which is attachable to the object and four or more beacons each positioned in separate fixed locations in or near the area of interest, The beacons have a primary beacon function and a secondary beacon function and the portable tag measures the time referenced signal from the beacon using its primary beacon function and the time referenced echo from the beacons using their secondary beacon function to calculate the position of the portable tag with respect to the beacon. A controller switches said beacons between their primary beacon function and their secondary beacon function to create a plurality of calculations of the position of the portable tag.

Abstract: A system and method for measuring the position of one or more object in an area of interest. The system has a primary beacon located at a first fixed position in or near the area of interest which generates a time referenced primary signal, two or more secondary beacons located at different fixed positions in or near the area of interest which generate time referenced secondary signals and one or more portable tag, the portable tag being attachable to the object. The portable tag has a portable tag circuit for calculating the distance of the portable tag to the primary and secondary beacons by means of a time of flight calculation which uses, the known position of the primary and secondary beacons, time referenced signals and delay information associated with the time referenced signals, such that the portable tag calculates its own position.

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.
