Descripció del contingut i pla d'activitats:
The recent introduction of mega-constellations and the rise of the 'new space' paradigm require rapid evolution in space networking. This trend reflects the increasing need for high-capacity and low-latency communication systems in space, aiming to integrate with terrestrial networks seamlessly. In this context, Optical Inter-Satellite Links (ISLs) have become a pivotal technology, promising faster data rates and reduced electromagnetic interference compared to their radio frequency counterparts. However, their implementation is challenging. During the mission design phase, decisions concerning terminal placements are paramount due to the high precision demanded by optical communications. Furthermore, the challenges associated with precisely pointing, acquiring, and tracking these links during the operational phases could benefit from innovative solutions, including a supporting low-rate radio-frequency control channel. This thesis addresses these issues by developing comprehensive discrete-event simulation models for optical ISL protocols. These models will provide a holistic understanding of the dynamics and intricacies associated with these communication links. Based on these, this work will extend to formulating novel design methodologies and operational algorithms. These innovations will address the current challenges and lay the groundwork for the robust implementation of optical ISL in future space missions.


1) Literature Review and Protocol Analysis. Survey existing protocols and methodologies utilized in optical ISLs. Identify gaps, shortcomings, or inefficiencies in the current solutions.

2) Design of Discrete-Event Simulation Models: Utilize DSS-Sim (i2Cat) to develop a preliminary Optical ISL model. Incorporate factors such as terminal placements, pointing, and protocol.

3) Implementation and Validate: Implement the chosen optical ISL protocols in the simulation model. Verify and validate the implemented model using simple scenarios.

4) Scenario Analysis: Run multiple simulation scenarios considering different configurations. Analyze the results to assess the robustness, efficiency, and reliability.

5) Algorithm Development and Validation: Formulate novel design methodologies and operational algorithms. Provide an outline on how to implement and address them in future works.
Orientació a l'estudiant:
The student should have (or be able to autonomously acquire by herself/himself) a background in networking and simulation.
