Projects

This project deals with the development and qualification of the next generation of Digital Transparent Processor (DTP) based on 28nm ASIC and optical high speed serial links technologies. Such DTPs will be able to process up to 2500 MHz useful band per access and to present high modularity for offering total capacity compatible of applications ranging from FSS/BSS, HTS & V-HTS needs.

The project focuses on developing a simulator, for analyzing interference scenarios related to Non-geostationary (NGSO) satellite systems. The main objective of this simulator will be to test and validate satellite system designs, including mitigation techniques, against various interference scenarios in which NGSO constellations and/or GSO satellites operate, with the definition of interference mitigation strategies, aimed at enable the coexistence of different systems in the same frequency bands.

Countries located in tropical climates are particularly interested in satellite communication systems, because they can provide telecommunication services to vast regions without the need to install large and costly terrestrial networks. The operation of current satellite multimedia communication systems is moving to Ka-, Q/V- and W-band. However, those frequency bands are severely affected by the atmospheric propagation of electromagnetic waves.
The accuracy of atmospheric and channel models is critical for the design of satellite communication systems, with the actual performance of propagation models for higher frequencies in tropical regions still not being reliably assessed.

The climatic difference to moderate climate can affect several design propagation parameters, including gaseous, cloud and rain attenuation, sky noise emission, site diversity, fade duration and fade slope. The propagation models currently recommended by the ITU-R for global predictions are based on empirical assumptions and on the use of Earth Observation or Numerical Weather Prediction data that cannot provide the same resolution (both in time and space) and accuracy as achievable through direct measurements.

The propagation experiments at these bands are the base for developing accurate propagation models to improve the utilization of the propagation impairments mitigation techniques (PIMTs), such as uplink power control (UPC), adaptive coding and modulation (ACM) and link diversity, which require the knowledge of first and second order statistics of rain attenuation.
The propagation campaign presented in this activity aims to assess the accuracy of current prediction models with focus on rain attenuation and to improve the models for second order statistical parameters such as fade slope, fade duration and site diversity gain.

This activity focuses on the design of a Q/V-Band gateway antenna that can be scaled in the range 7 to 13 meters for future Feeder Link gateways.

SATBETT-5G aims to develop an integrated set of consultancy, prototyping and certification services in the context of 5G private mobile networks over satellite. The long-term goal is the commercial offer of a network-as-a-service platform, driven by the virtualization of terrestrial and non-terrestrial networks and a slicing of the network to tailor the consumer needs. The short-term goal is to provide consultancy services and training to entities planning to build satellite backhauling infrastructures.

The project’s outcomes deal with the design, implementation, test and demonstration of a prototype backhauling solution (satellite terminal, satellite gateway and NB-IoT network functions) which is capable of providing NB-IoT backhauling services. The purposes of this activity is using the latest satellite backhauling technologies and standards in order to provide a more efficient backhauling of NB-IoT cells over satellite. The prototype is embedded in a testbed which represents a realistic environment with regard to a future deployment.

Satellite communications industry has been growing rapidly over recent years. There has never been more satellite launches than we have had in the last two years with all the LEO launches. Diversity of satellites, new transmission modes and optimization techniques combined with proprietary standards is all adding complexity to an already challenging environment. As the number of satellites increases, it is expected that the number of interference cases increases as well. This leads to a significant higher amount of effort for satellite operators to identify interference cases.
AI has the potential to be a game changer in the satellite industry, where it could be used to improve processes and increase efficiency. AI could establish a digital assistant, capable of processing information about everyday satellite procedures, resolving and predicting issues before they become errors.
