Abstract: Methods and apparatus for generating site health information are disclosed herein. An example apparatus is configured to generate a hub quality matrix, wherein the apparatus comprises a processor and memory including machine-readable instructions that, when executed, cause the processor to generate the hub quality matrix using at least two values of a data quality value based on the received location data, a receiver health value based on a receive rate of respective ones of the receivers, a locate gap value based on amounts of time between location estimations, a locate rate value based on a ratio of a first amount of the location estimations and a second amount of tracked participants at the site, and to output the hub quality matrix.

Abstract: A non-transitory computer-readable medium storing a plurality of computer-readable instructions executable by a processor, wherein execution of the instructions configures the processor to: obtain location data representing a ground path of a flight of an object; determine, from the location data, a first ground distance and a second ground distance traversed by the object during an ascent phase and a descent phase of the flight of the object, respectively; determine an initial angle of the flight of the object; determine an initial airspeed of the object based on the determined initial angle; determine an air drag value for the object during the flight based on the determined initial angle and the determined initial airspeed; output a flight path of the object, the flight path representing a three-dimensional path travelled by the object during the flight and determined based on the initial angle, the initial airspeed and the air drag value.

Abstract: Methods and devices for determining a load vector on an object are disclosed herein. An example method includes collecting location observations related to the object. The example method further includes filtering the location observations to determine an estimated model path. The example method further includes outputting a set of data from the estimated model path, wherein the set of data includes a model location, a model velocity, a model acceleration, and a model jerk. The example method further includes calculating a load vector from the set of data, scaling the load vector via a scaling index, and transmitting the scaled load vector to a remote device.

Abstract: Methods and apparatus for generating site health information are disclosed herein. An example apparatus configured to receive location data generated based on blink data transmitted by tags and received by receivers deployed at a site includes a processor; and memory including machine-readable instructions that, when executed, cause the processor to: generate a data quality value based on the received location data; generate a receiver health value based on a receive rate of respective ones of the receivers; generate a locate gap value based on amounts of time between location estimations; generate a locate rate based on a ratio of a first amount of the location estimations and a second amount of tracked participants at the site; and generate site health value by combining two or more of the data quality value, the receiver health value, the locate gap value, and the locate rate value; and outputting the site health value.
