The GomSpace 6U professional platform has been designed as a standardised mid-level 6U CubeSat. This model can accommodate missions with high power requirements, high data volumes and precise ADCS requirements. The platform has a data link system which consists of S-band up- and down-link and X-band downlink.  

The GomSpace 6U professional platform provides: electrical power management, deployable solar panels, precise ADCS (star tracker), TMTC, OBC functionalities, and S-band and X-band data links. Propulsion (cold gas or electric) can be provided on request.   

More information can be found in the GomSpace Platform White Paper.
