| Overview (resum en anglès): | |
| Optical Inter-Satellite Links (OISLs) are emerging as a key technology for future satellite communication networks, offering higher data rates, narrower beam divergence, reduced interference vulnerability, and improved spectral efficiency compared with conventional radio frequency (RF) systems. This thesis presents an engineering-oriented study of OISLs, beginning with the limitations of RF satellite communications and developing an analysis of the fundamental operating principles, transmission and reception terminal architecture, and free-space propagation effects.
The work also reviews the principal modulation formats, laser sources, and propagation impairments relevant to OISL design, with emphasis on their impact on link budget and signal quality. In addition, current applications and representative systems are presented to illustrate the current state of the art in optical satellite communications. Finally, the thesis identifies the main technical gaps and open challenges that still remain unresolved. Overall, the study concludes that OISLs are a highly promising technology for future constellations, but their operational maturity depends on further advances in system design, control accuracy, and standardization. |
