Proposal for a CubeSat probe constellation to map Titan's atmosphere

In this paper, we propose the design of a mission to investigate Titan. The core part of the mission are the CAPOs (Cubesat Atmospheric PrObe) which are 2U CubeSats that will be used as probes to collect data while they are descending Titan's atmosphere. In the paper, we present the design of the CAPOs and the design and build of a CAPO prototype, using easily available components. The scope of the CAPOs is to measure relevant scientific data of Titan's atmosphere, for this purpose they will have a set of sensors to measure parameters such as: Temperature; Atmospheric pressure; Methane; Carbon dioxide; High energy particles; Ultraviolet light; Magnetic field. All of these need their location to be determined. In order to do that, we propose the use of NAVSATs (NAVigation SATellites). We will discuss their design and requirements. We also propose the user requirements and the overall design of some subsystems of the MOTHER (Master Orbiter for Titan atmospHEric Research), which is the satellite that will be orbiting Titan and will dispense both the CAPOs and the NAVSATs. Once the NAVSATs are deployed, they will get in the desired orbit to be able to transmit navigational system to the CAPOs. Once the CAPOs are deployed (one b
