Objectives
– Improve the characterisation of the radio channel modelling and ground system requirements for the development of a Ka band SatCom systems covering tropical regions.
– Assess the accuracy of current prediction models with particular regard to statistical distribution of rain and cloud attenuation.
– Improve the statistical models for the parameters describing: signal fade slope, signal fade duration and gain of site and time diversity techniques.
– New models and input data shall be used as input documents to radio regulatory bodies (e.g. ITU-R).
Challenges
To fill the need of real propagation figures and ITU standards for the design of broadband satellite communication systems for market regions with tropical climates (Brazil, Africa, India, Indonesia and Oceania).
Plan
This activity will perform an experimental campaign to collect propagation measurements at Ka band. The campaign will last 1 year and will include beacon receivers and auxiliary equipment over 2 sites.
The activity is structured in the following phases:
– Design of the Instrumentation and planification of the Experimental Campaign
– Instrumentation development, manufacturing and testing. Site preparation and on site tests
– Measurement campaign
– Statistical analysis
Current Status
Instrumentation development, manufacturing and testing. Site preparation and on site tests.
