 D-STAR digital amateur communications in space with OUFTI-1 CubeSatPisane, Jonathan  ; Denis, Amandine ; Verly, Jacques Article for general public (2013) OUFTI-1 is a nano-satellite currently being constructed by the students of the University of Liège, Belgium. Its main payload is the D-STAR amateur-radio telecommunication protocol. In this paper, we ... [more ▼] OUFTI-1 is a nano-satellite currently being constructed by the students of the University of Liège, Belgium. Its main payload is the D-STAR amateur-radio telecommunication protocol. In this paper, we explain how hams will be able to operate OUFTI-1 for D-STAR space communications. The large footprint of OUFTI-1 results in a larger number of users being able to communicate via D-STAR.

[more ▼] A major issue in the design of a D-STAR radiocommunication system for a satellite is the issue of Doppler shift compensation. We describe the various constraints we faced, and the solutions we implemented on-board and on the ground for the OUFTI-1 nanosatellite system.
