KEYNOTE: Advanced Simulation Tools for Satellite Coverage and Interference Analysis

Satellite networks play a crucial role across various domains, including Global communication — Delivering connectivity in remote and rural areas lacking terrestrial infrastructure, Navigation & positioning — Supporting precise operations in aviation, maritime, and automotive applications, Environmental monitoring — Enabling land use assessment, ecosystem analysis, and sustainable planning and Defense applications — Facilitating reconnaissance, surveillance, and secure communications. This talk will present advanced simulation tools for streamlined workflow for evaluating satellite radio coverage across diverse scenarios as well as provide essential methods for evaluating the ground/space coverage for satellites/earth stations, assessing inter-satellite links, examining interference for satellite networks, evaluating frequency sharing feasibility between space and terrestrial services, and Earth Station Coordination. This talk will include challenges in the antenna design simulation that may also include radome structures. Satellite radio channel modelling will be presented with an example of a GNSS antenna design to the prediction of received satellite signal including the multipath effects. A case study of non-terrestrial network (NTN) will be presented using the LEO (low earth orbit) satellite as an example. Another challenging issue for satellite networks is the noise increase in the receivers in satellite networks due to other satellite networks as well as colocation interference of multiple antenna systems on a satellite platform. This talk will address a very wide range of applications including antenna design & placement, radio coverage & channel, EMC, multiple interference scenarios, co-existence of radio networks and spectrum management.
