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.

The project realizes a first commercial network of optical stations that can be used for supporting optical payloads on any spacecraft.

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 could establish a digital assistant, capable of processing information about everyday satellite procedures, resolving and predicting issues before they become errors.
