Abstract: [ANGLÈS] The goal of this thesis was to study the feasibility and scalability, in terms of communications, of the ABS project which is being developed at the Technical University of Catalonia UPC BarcelonaTech with educational purposes aiming to design a phone-based nano-statellite (or PhoneSat). The satellite will be able to establish connections with both the ground segment and other nano-satellites through the standards compatibles with the mobile device such as GSM, WCDMA, HSDPA, LTE, Bluetooth and WiFi. The main focus of study was the development of an optimization-based methodology in order to design the physical layer of the communication WiFi link taking into consideration that the ABS project amis to provide its services to a multiple type earth community. Thus, it has been made the optimization of the data downloaded by both users so that they are maximized under certain criteria such as the size of the receiving antenna and the power transmitted by the PhoneSat in order to benefit both ground and space segments. Finally, the optimization methodology has been applied and several scenarios as well as a scalability analysis are presented with the purpose of showing how optimal parameters change as the number of users varies. Additionally, it has been done a brief study to determine which is the best technology to establish a communication among phone-based satellites depending on the distance between them, exploratorily aiming nanosat constellation.
