The paper, “Validation of ground technologies for future Q/V band satellite systems: the QV – LIFT project” will be presented to the 2018 IEEE Aerospace Conference on March 3rd in Big Sky, Montana.
This paper depicts key hardware and software developments for next generation HTS systems operating in the Q/V band which are under development in QV-LIFT project. With the aim of supporting the Terabit connectivity, High Throughput Systems – HTS relies on the exploitation of Q/V band. These frequency bands offer the possibility to have larger bandwidth availability with respect to the Ka band systems, and to realize feeder links and specific segments requiring high data rates such as aeronautical in-flight services. The design of a Ground Segment for Q/V band satellite communications implies several technological challenges. The design of antennas, power amplifiers with high efficiency and Low Noise receivers are critical, nevertheless they are fundamental to support high data rate transmissions. Furthermore, in order to counteract atmospheric impairments, a system must be able to implement and to manage a handover mechanism between gateways is also needed.
A Ground Segment for Q/V band high throughput system has been conceived in the project QV-LIFT. The consolidation of crucial technologies for new generation satellite communications is addressed, with the objective to ensure space accessibility to Europe and, in particular, to foster technology readiness of European industries in space related sectors.
This paper provides the description of key hardware and software developments for next generation HTS systems operating in the Q/V band, based on core technologies for both ground and user segments currently under development for the project QV-LIFT. The system test architecture which will be used to validate the developed technology and functionalities is also presented, together with the overview of the project status and validation plan.
