Artificial satellites are man's design tools that allow us know more about space and our planet, these satellites are designed with the idea of capturing and sending endless data and variables and being discharged to the ground and make a relevant analysis . But this process can be divided into three parts, the first, the capture of this data, whether temperature, images, atomic particles, etc. The second one, the fact of download this information and how it manages to bring these data to the earth. This second phase is the focus of this article, because depending on the type of data you are interested download some changes are needed in the transmission equipment, modified frequencies, antennas, protocols and other variables discussed in this paper; and finally the third phase is to give sense to this data, analyze it and to find an application or use in society.
