Estudio y diseño de un prototipo de sistema GPS diferencial móvil en tiempo real, para la localización de equipos ubicados a la intemperie para un área de cobertura de 10 km

Abstract

In the present work, a positioning error correction system has been implemented to analyze the behavior of the DGPS (Differential Global Positioning System) and for the effect have been considered: real time, inverse differential correction and geodesic control points IGM (Institute Military Geographic). The development of the project is carried out by the configuration of the radio modem ZRT Data of RF DataTech receiver and transmitter using the WinA4P software in order to obtain the necessary data for the study. Using the serial ports of the computer, the information is taken from both the base GPS and the mobile GPS (rover) and with the position correction program made in LabVIEW to have usable and coherent data for the analysis of obtained results. For the implementation of the platform for the transmission - reception of information, radio modems that work within the VHF frequency range are used and the information is displayed in real time. Additionally, through the graphic interface of the computer, the data acquired by the system can be exported to a file.txt so that the user can analyze them.
