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...
In this paper requirements, specifications and preliminary system design of a mini-satellite flower constellation for millimeter-wave atmospheric observations are presented together with the main payload technological characteristics. This work has been performed in the frame of FLORAD Phase A project (mini-satellite FLOwer constellation of millimeter-wave RADiometers for atmospheric observations),...
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...
Q/V band frequencies are expected to play a key role in enabling challenging and unproven broadband communications missions for a wide range of applications. In the perspective to exploit these frequencies, several satellite missions have been proposed to explore the physics of the satellite channel. The strategic importance of probing higher and higher frequencies has been recognized by the Italian...
WAVE (W band Analysis and VErification) is a project funded by the Italian Space Agency (ASI) with the aim to design and deploy different missions for scientific experimental use of the W band channel in satellite data communications. The second phase (A2) of the Project is currently in progress. This paper summarises the main scientific results early achieved in the WAVE A2 Project on the analysis...
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...
In this paper, an overview of the WAVE mission payload architecture is presented. WAVE (W-band Analysis and VErification) is the new project funded by the Italian Space Agency (ASI). The aim is to design and develop a W-band geostationary (GEO) payload to be deployed for scientific experimental studies of the W-band channel and possible utilization in satellite data communications. The large bandwidth...
WAVE (W-Band Analysis and VErification) is a new project proposed for the Italian Space Agency (ASI) to design and develop a W-band geostationary payload aimed at the experimental studies of the W-band channel and possible utilization in satellite data communications. In this paper, an overall description of this mission is presented, in addition to the different atmospheric parameters that affect...
