Objectives

The objectives of this project are to review and develop channel models, data and tools tailored for the design of High-Capacity Flexible Broadband Satellite Systems operating (Q/V and Ka Band) with a major focus on future system at Q/V Band. In particular, 
  • Review and improve the applicability of current propagation models
  • to future HTS operating at Q/V band.
  • Identify and model the statistical error margins of the propagation models for Q/V band FSS systems.
  • Develop and implement system optimisation algorithms for the design of Q/V Band system that takes into account propagation effects. These algorithms are implemented in a SW tool to be used by system engineers.
  • Define criteria, thresholds and algorithms to be used in the execution of future campaigns at Q/V Band in which propagation measurements are used to control and verify the execution of a telecom experiment.
  • Submission of experimental tables and results of model testing to ITU-R

Challenges

The project’s aims are to identify the challenges of migrating to Q/V band (e.g. severe atmospheric attenuation) and propose relevant solutions. Particular emphasis is given to
  • the modelling of the uncertainty of the required propagation models 
  • the development of a  user friendly SW tool which implements the required optimization algorithms.

Plan

The project is divided into three tasks:
  • The first task consists of a state-of-the-art review (System Architectures, Propagation Review), preliminary design of the SW tool and a review of planned satellite experiments at Q/V band.
  • The second task consists of:
    • Improvement/Development of the required propagation models, the associated modelling of the uncertainty of the predictions and implementation in SW procedures
    • Development of optimisation algorithms
    • Final design of the SW tool.
  • The task 3 consists of the implementation of the design tool, description of future algorithms for telecom campaigns and the final reporting (including new ITU-R input documents and data tables).

Current Status

This project is currently undertaking the state-of-the-art review.
