Communication system design and implementation for one pico-satellite and four earth stations using AX.25

This paper will describe all the hardware and software necessary to implement a pico-satellite network and 4 earth stations. The mission of the CubeSat, Colombia 1, Distrital University's project, consists of taking ECG signals at an earth station and send it via pico-satellite to another. It was initially described as a network in the laboratory as wire is then implemented as happened to a wireless network.
