Es tracta de dissenyar diverses practiques docents de Telecomunicacio Espacial amb la possibilitat de ser utilitzades posteriorment en l'assignatura Communications Navigation and Surveillance. Es desenvoluparan enunciats i solucio/ns relacionats amb l'assignatura per fer us del programa STK, amb el proposit de donar un suport visual i practic als conceptes i exercisis de comunicacions per satelit, alhora que apropar aquest potent programari a l'estudiant i veure les seves possibilitats en el diseny de sistemes de telecomunicacions espacials. L'estudiant del TFC haura d'apendre a dominar aquest programa, aprofundir els conceptes de l'assignatura CNS, i seleccionar i disenyar unes practiques amb STK que permetin contribuir a la docencia d'aquesta part de l'assignatura. |

Abstract:

The present TFC englobes a series of practicals that involve STK software.
They have been designed as a possible application for the CNS
(Communications, Navigation & Surveillance) subject, more specifically for the
chapter about Satellite Communications.
Firstly, different software that simulate satellite communications is described,
along with its functionalities. Most of them are user-friendly and part of the
public domain. A comparative analysis of the main attributes of each software –
recommended by ITU-R – and of common satellite links models is presented
subsequently.
Secondly, STK software is described and its main functionalities are enlisted.
The main part of this present work is a collection of three practicals of spacial
communications subject that involve the previously mentioned software.
The first practical is an introduction to this software and uses 3D potential so
that students are familiar with typical telecom satellite orbits. Furthermore, the
users learn to visualize orbital parameters, 3D moving vectors, effects of
parameters on ground track on a 2D window, and the comparison of different
orbits for the understanding of their pros and conts.
The second and third practicals present typical case studies of this chapter of
CNS subject that have been resolved with the communications module of STK
Professional. Advantages of different propagation models are analysed,
several instrumentation options and the effects of every link parameter are
studied as well. Summarizing, these two practicals are tutorials for the
simulation and comparison of different satellite links, their coverage, effect of
interferences, and different tools for generating reports. |
