| "Traditional COMM boards in CubeSat and nanosatellite missions using amateur radio bands are based on the use of separate UHF transmission and VHF reception paths. Both half-duplex and fullduplex schemes can be found in other CubeSat missions. Available COM architectures do not include any redundancy mechanism that can deal with the malfunctioning of the either transmitter or receiver. In case of communication failure, the mission might be unsuccessful or the objectives of the mission could be severely degraded. The introduction of modern transceivers brings the possibility to define new communication schemes that include additional functionalities in the COM subsystem. Taking the QBito nanosatellite mission as a reference, we present new COM architectures that make use of all the functionalities of modern transceivers to reduce the population of components in the COM board. The advantages brought by these transceivers to CubeSat communications are explained. A redundant COM architecture is presented along with a reconfigurable COM scheme. The impact to the other satellite subsystems, integration with antennas and requirements on the ground segment are highlighted." | |
