Análisis e implementación del servicio de outernet por medio de micro satélite para la recepción de información en el laboratorio de microondas y comunicaciones de la Facultad de Informática y Electrónica

Abstract

The purpose of the present titling work is the analysis and implementation of the outernet service through micro-satellites for the information reception in the laboratory of microwaves and communications of Informatics and Electronics Faculty. The project consists of three phases, in the first phase, three types of antennas are designed: Double Cross, Turnstile and Yagi; the first two destined to the reception of satellite images and the third one for obtaining the telemetry of the Cube Sat of OSCAR-AMSAT family; six scenarios are also considered based on weather conditions, antenna type and place of reception inside and outside the city, the information that is captured is encoded by using a USB dongle called RTL-SDR, device with free software such as Wxtolmg, SDRsharp, Orbitron and Fox Telemetry Anlisys Tool that works for the decoding of the information, thus completing the second phase; Finally this information is stored in a local server based on WAMP-SERVER integrating services as an Apache server, Mysql and language based on PHP to be distributed through a LAN network reaching the third and final phase of implementation. Images with different levels of SNR are obtained according to each scenario, resulting the Double Cross antenna more suitable than the Turnstile antenna for the reception of satellite images, the best scenario being a wide environment away from contamination by other communication systems that exist in the big cities and as for the OSCAR-AMSAT satellites, the yagi that is designed and implemented, worked correctly. It is recommended for future works to implement the outernet service with the Dreamcatcher card because it has better features than the RTL-SDR dongle. Keywords:
