  • All-IP Broadcast Satellite Networks Technologies and Demonstration

    Status date: 24 February 2016

    The arrival of new Ka band satellite services comes with dramatic reduction in bandwidth cost, multi-spotbeam capabilities and dynamic signal strength allocation, increased transport capacity and improved interactive possibilities. Ka band services enable an IP based paradigm for delivery and consumption of content, allowing for a more personalised, on-demand driven user experience. This project will give the answer to the question how to deliver these new Ka band IP based content services to end users, taking into account the context of terrestrial network developments. Since Ka band services will become part of the IP world of service delivery, integration with next Generation Networks (like IMS) is essential in facilitating the uptake of these services.

  • AISMAN – Miniaturized Low-Weight Space Antenna for AIS VHF Applications

    Status date: 24 February 2016

    Aim of the AISMAN project is to design, manufacture and test a miniaturized space array antenna suitable for SAT-AIS application. Miniaturization is understood as a technique to reduce the size of the antenna in stowed configuration. Both techniques to reduce the physical dimensions of the single-element antenna and techniques to fold/deploy the final array antenna aperture have been considered. After trade-offs at element and array level, a miniaturized antenna element, working at VHF frequencies and suitable for AIS applications, has been studied, designed, manufactured and extensively tested. The design process has been refined and validated through experimental measurements, providing a valuable design tool for further antenna design steps. The antenna element has been also tested in embedded array configuration, with inclusion of a satellite mock-up, and compliance to the array requirements has been demonstrated. A parallel study on DBF techniques has been carried out. An additional activity (CCN-01) has led to the design, manufacturing and full test (RF & thermal) of an improved antenna element, moving a step closer to flight model production. The test outcomes show that the initial trade-offs could result in different element selection if driven by specific mission requirements. Such requirements can set different weights to the trade-off marking, driving the selection of the element accordingly. The flexibility of the element design allows accommodating this selection process. A Design, Development and Test Plan has been prepared, considering non-recurring and recurring costs for a batch production of up to 30 FM items.

  • Q/V-band Frequency Converter

    Status date: 02 February 2016

    The need for bandwidth in satellite communications and broadcasting is constantly increasing. It is foreseen that, in some locations, the capacity at the Ka-band alone will not be sufficient to allow for the emergence of new applications such as broad-band internet, satellite-HDTV, live video, telemedicine, interactive gaming, video conferencing, and others. The exploitation of higher frequency band (Q/V) will offer a substantial increase in the capacity for the needs of both public and private sectors using satellite services. It is expected that Q/V-band will first be used for gateway access.

  • SPARR

    Status date: 28 December 2015

    Today there is a growing demand for large aperture antennas exhibiting increased capabilities (in terms of flexibility, reconfigurability, frequency bandwidth, and field of view) and reduced cost and complexity. Sparse arrays represent an effective architecture to achieve high performance while minimizing the number of controls for a limited field of view or wide band array. Sparse arrays, based on non-regular lattices, are a valid alternative to periodic arrays because they are able to generate an equivalent tapering by adjusting the element positions. They also allow reducing the number of elements, and increasing the DC to RF overall efficiency of the antenna. In this activity the optimization of the irregular array layout has been done in such a way to satisfy the required radiative performance keeping at the same time a simplified beam forming network and cooling system (e.g. heat-pipe).
