- Rainfall rate and rain attenuation contour maps for preliminary “Simon Bolivar” satellite links planning in Venezuela Angel Dario Pinto-Mangones Nelson Alexander Pérez-García Juan Manuel Torres-Tovio Eduardo José Ramírez Samir Oswaldo Castaño-Rivera Jaime Velez-Zapata John Dwiht Ferreira-Rodríguez Leidy Marian Rujano-Molina Ingeniería integration Contour maps time conversion satellite links rain rate prediction Predicting precipitation rate and rainfall attenuation are key aspects in planning and dimensioning of wireless communication systems operating at frequencies above 10 GHz, such as satellite communication systems at Ku and Ka-bands. In this paper, contour maps of rainfall rate and rain attenuation are developed for the first time in Venezuela. It is based on 1-min rain rate statistics obtained from measurements carried out in Venezuela over a 30 years period with a higher integration time. The Rice-Holmberg model, refined Moupfouma-Martin model and Recommendation ITU-R P.837-7 for rain rate estimation were used, while Recommendation ITU-R P.618-13, Ramachandran-Kumar model, Yeo-Lee-Ong model and Rakshit-Adhikari-Maitra model were used for rain attenuation prediction in “Simón Bolívar” satellite links in Venezuela. The results of both types of maps represent a useful tool for preliminary planning of those links in the country, specifically, in Ku and Ka-bands. 2019 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49662418004 https://www.redalyc.org/journal/496/49662418004/ https://www.redalyc.org/journal/496/49662418004/html/ https://www.redalyc.org/journal/496/49662418004/49662418004.epub https://www.redalyc.org/journal/496/49662418004/movil 10.15446/dyna.v86n209.73774 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.209 Vol.86
