LOCATION AND TRACKING OF PEOPLE WITH COMBINED USE OF RF INFRASCTURE AND DEAD RECKONING MODULES
摘要
A system for tracking persons and other assets in a structure, having a mutli-function tracking tag and a network of fixed RF receivers forming a gateway array. The location of the person being tracked is calculated by a computer using an algorithm that weights each separate signal according to the probability of its accuracy, thus using data with the least error. A preferred algorithm is shown in Fig. 2.
