ACTIVITY CODE | 3B.025

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  the identify  the challenges of migrating to Q/V band (e.g. severe atmospheric attenuation) and propose  relevant solutions. Particular emphasis is given to

i) the modelling of the uncertainty of the required propagation models

 ii) 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:

i)             Improvement/Development of the required propagation models,  the associated modelling of the uncertainty of the predictions and implementation in SW procedures

ii)                    Development of optimisation algorithms

iii)                  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.
