Diseño de un sistema prototipo para transmisión de imágenes de estaciones meteorológicas a través de la red celular para brindar soporte al personal técnico de meteorología del INAMHI

Abstract

Nowadays to give a weather forecast, weather sensors and mathematical models are been used, however this methodology is not sufficiently precise and correct to perform this task, so that the forecaster needs to observe the clouds pattern of a certain point during a period of time. This procedure may seem relatively simple, however it is impossible for meteorologist to be present in several places at the same time, in order to resolve this issue a prototype system for sky image transmission has been developed. The pictures obtained are sent via the cellular network to the communications center INAMHI (National Institute of Meteorology and Hydrology) in order to be used for weather forecasting. For the development of the prototype has been used the open source hardware platform Raspberry Pi, a camera fitted with a fisheye lens, a GPS (Global Positioning System) receiver and a 4G LTE (Long Term Evolution). The information is transmitted every 5 minutes during the day and it is received in a FTP (File Transfer Protocol) server located at the INAMHI institute.
