Localización de ob jetos en rangos cortos en real-time usando señales de radiofrecuencia

Abstract

The objective of this study was to define the reasons why study and implement systems that locate objects with transmission and reception devices with signals of radiofrequency and computers that process these signals, and then study the existing mathematical methods of locating objects by trilateration, technology in transmission devices, communication standards, low level and soft real time programming available, and models of operation and system design, choose the most suitable ones, and verify the feasibility of implementing a system to locate an object in real time in a small closed environment with the implementation of the concepts mentioned. In order to reach this objective there were several tests of locating an object in an closed environment that permit to analyze specific parameters such as the precision in the estimated position of the object and the response time provided by the system, the negative effects of the physical phenomena present in the environment on these parameters and how to mitigate them through an analysis of the margin of error in the estimated position of the object by an scaling of the margin of error and using techniques of real-time programming that optimize the response time of the system, to get a system that can be used as a complement to the Global Positioning System (GPS).
