| Headline Details: A 3U CubeSat mission. The goal of the ROBUSTA-3A mission is to: 1) Mission 1: Collect and retransmit climate data from transmitters on board ferries to the GS in Montpellier. We want to measure the amount of water particles contained in the troposphere forming over the Mediterranean through the deviation of a GNSS signal. And thus demonstrate whether this method would make it possible to improve forecasts of the Cévenoles and Mediterranean episodes. 2) Missions 2: An S-band transmitter is on board operating in commercial band. We want to test our ability to use our space and earth equipment for future scientists missions. 3) RadioHam: 4)The HAM radio messaging system provides a message-exchanging service between amateur radio users using Robusta satellite missions as relays. The main purpose of the system is to enable HAM radio operators to send and receive messages from anywhere in the world without having a direct (end-to-end) connection between them. The messaging system uses a method called ‘store and forward’ to provide this service. Messages are transported to the relay station (satellite) by a radio link, and from one geographical location to another, by the satellite orbital movement. An user sends a message to the satellite during a pass and the message is stored in the satellite’s memory. The satellite then moves on its orbit, making the stored message available for other HAM radio operators. Users can request messages to the satellite which, in turn will check if there are any stored messages available for that particular operator. Finally, the message is transmitted and it arrives at its destination. Educational: No less than 300 students participated in the development of the platform. As pa rt of their training, a module is allocated to the initiation to amateur radio. In addition, we pass the license to around ten students each year with the ANFR (French administration). Proposing a UHF downlink using 9k6 and 38k4 GMSK AX25 format. Planning launch on Ariane 6 maiden flight June/July 2024 into a 580 km 62 degree orbit.
