This paper presents a summary of the project: “Q/V band earth segment Link for Future high Throughput space systems” (QV-LIFT), recently funded in the framework of the EU program Horizon 2020. The project aims at developing up to date hardware and software technologies for the Ground Segment of the future Q/V band terabit Satcom infrastructure.
This paper presents an overview of the activities performed by the Agency in the framework of the Alphasat Aldo Paraboni scientific experiment at Ka and Q band. In particular it addresses the technological developments for the equipment of the propagation campaign, the execution of mission related activities, the execution of propagation campaigns, the international cooperation with the group of propagation...
The Large Hadron Collider at CERN restarted in 2015 with a higher centre-of-mass energy of 13TeV. The instantaneous luminosity is expected to increase significantly in the coming years. An upgraded Level-1 trigger system has been deployed in the Compact Muon Solenoid experiment, in order to maintain the same efficiencies for searches and precision measurements as those achieved in the previous run...
The Q/V Band program of ASI involves two main elements: the “Space Segment” and the “Mission Segment”. The Space Segment is represented by the Technology Demonstration Payload TDP#5, the “Aldo Paraboni” P/L. Financed by Italy through the ARTES-8 Program, it has been developed by the European Space Agency and implemented by italian space industries. It has been embarked as hosted payload on Alphasat...
The Alphasat satellite was launched on 25 July 2013. The Aldo Paraboni technology demonstration payload, funded by ASI under ESA's ARTES Programme, was embarked as an hosted payload on Alphasat. This Technology Demonstration Payload (identified as TDP5 and recently renamed “Aldo Paraboni”) was implemented under an ESA contract awarded in co-contractorship to Space Engineering and Thales Alenia Space...
Broadband satellite communication systems, with their global access and broadcasting capabilities, are assuming an increasing relevance in the framework of modern Information Society. These systems could greatly benefit from the use of Extremely High Frequency (EHF); in particular “beyond Ka-band” frequencies can provide the advantage of large bandwidth availability but also smaller antenna size for...
The Alphasat Aldo Paraboni communication experimental campaign is based on a transparent Q/V band transponder hosted as a piggy-back on a GEO satellite. Together with the transparent payload, two beacons having European coverage, one in Ka-band and one in Q/V-band, are used to perform propagation experiments.
Future satellite communication systems providing broadband access to Internet require high throughput connectivity in the order of hundreds of Gbps or Tbps. Radical changes in technologies are needed to support these demanding requirements. One of the most important changes is the use of Q/V band frequencies which offer larger bandwidths with respect to the Ka band. However, Q/V band communication...
The paper describes the integration phase of the ALPHASAT Technology Demonstration Payload #5 (TDP#5) Mission Segment that, in conjunction with the TDP#5 payload, embarked in the Alphasat Satellite will allow the execution of communication experiments at Q and V frequency bands, and propagation experiments at Q and Ka bands. The TDP5#5 Mission Segment (TDP#5-MS) major constituents are two Italian...
Nowadays, climate and meteorology assumed a fundamental role in manifold domains with the aim to understand how they affect life in modern society. Such a new sensitivity is the result of a major awareness of the Earth health and the need of better understanding the increasing climatic and meteorological changes recently observed. Actually, in the last years several satellite missions, single and...
An increasing interest is arising on the exploitation of the Q/V bands for telecommunication applications, in order to cope with the greater and greater demand of bandwidth resources. The development of a mission in the Q/V band was preliminarily investigated by Space Engineering in the framework of an Italian Space Agency (ASI) program dedicated to the Q/V-band. Afterwards, the innovative QV-band...
Since the 70s Italy has had a pioneering approach to higher frequencies, at first at Ka band (20/30 GHz) with the Sirio experience (launched in 1978), when such a range was still a frontier, and then with Italsat F1 and F2 experiments in the 90s, studying Q and V bands in addition to Ka one as well. After those experiences, Italy through the Italian space agency (ASI) was one of the first European...
Broadband technologies are taking a predominant role in the emerging information society. In particular, broadband satellite communication systems, with their global access and broadcasting capabilities, are well suited to answer to the requirements of the information society. This paper focuses on the efforts that are currently spent toward the development of EHF (Extremely High Frequency) satellite...
This paper gives a summary of some propagation- and radar-measurements carried out (or to be carried out in the next future) in the Spino d'Adda station (near Milano) with particular emphasis on the ones utilizable to support some of the future advanced techniques known as propagation impairment mitigation techniques (PIMT) that will see the light in the next decade. In the past some measurements...
In the last years scientific community has been witness of the growing interest in global EHF satellite systems for broadband communications; these systems can help national and regional telecommunications service operators to provide broadband communications in areas not adequately served by terrestrial systems. In this paper main EHF satellite missions are presented, outlining challenges and future...
The development of a technology demonstration payload for experimental broadband communications at Q/V bands has been funded by the Italian Space Agency. This payload will be embarked on the Alphasat satellite for testing fixed broadband ground-satellite communication services. However, the interest in the further experimentation of aeronautical mobile satellite communication services has been recognized...
Starting from 2008, the CMS experiment will produce several Pbytes of data every year, to be distributed over many computing centers geographically distributed in different countries. The CMS computing model defines how the data has to be distributed and accessed in order to enable physicists to run efficiently their analysis over the data. The analysis will be thus performed in a distributed way...
It is recognized that W band will be one of the frontier of satellite communications. Pioneering work on the scientific testing of high frequency satellite communications have been DAVID (data and video interactive distribution) mission and WAVE (W band analysis and verification) project, both of them funded by the Italian Space Agency (ASI). The WAVE project was a feasibility study carried out in...
This paper presents the payload design for an in orbit test of W band technology called IKNOW mission (In orbit Key-test and validatioN Of W band). The increasing demand for frequency bands with large bandwidth availability to satisfy satellite communications applications requirements renders mandatory the need to explore higher and higher frequency ranges. W band (75-110 GHz) could represent the...
