Sistema de localização híbrido baseado em nuvem para ambientes internos e externos

Abstract

With the emergence of global positioning systems (GPS), several applications could be designed based on location services, logistics chains, games, agriculture, business, security, among other applications. In this way, GPS allows obtaining locations in an external environment with some accuracy and about one centimeter of accuracy using the GPS with real-time kinematics (RTK). RTK GPS systems, however, are still expensive and rely on individual base stations and have their performance degraded indoors, or even outdoors in the presence of trees or clouds. Also, there is a growing need to locate mobile devices, such as tablets and smartphones, or even indoor mobile robots, where GPS does not work well. Thus, this work proposes a hybrid location system capable of using different technologies to provide indoor and outdoor location of mobile robots or other devices. For outdoor location, the GPS technology was used. For indoor location, Animalltag Chiip 01 Bluetooth Beacons trilateration and Wifi Node MCU (ESP8266) trilateration were used. Moreover, a cloud system was developed for the hybrid location system to process, store and visualize data.
