Descripció del contingut i pla d'activitats:
Se trata de explorar y analizar las tendencias actuales y futuras relacionadas con las tecnologias y sistemas de comunicación utilizados en los satélites de comunicaciones del ámbito New Space.

En concreto se exploraran los aspectos relacionados con los sistemas 5G/6G aplicados al ámbito espacial, los sistemas de ciberseguridad aplicables, en especial los sistemas de encriptación quántica, y los sistemas de comunicación para flotas de satélites.
 
Overview (resum en anglès):
The objective of this project has been to analyse satellite communication systems in Low Earth Orbit (LEO) constellations within the New Space context, as well as their integration with non terrestrial networks (NTN) in the 5G/6G ecosystem. This integration aims to ensure connectivity and Internet of Things (IoT) services in rural or remote areas, while maintaining service continuity and compliance with international telecommunications regulations.
Specifically, the structure of the space and ground segments has been studied, together with the types of links (uplink, downlink, inter satellite and TT&C) and the physical constraints of the channel, including losses, delay, Doppler, visibility windows and revisit time. The regulation of the ITU and the 3GPP Release 17 specifications has been analysed, identifying frequency bands, power limits and operational parameters relevant for broadband, MSS and satellite IoT services.
In addition, cybersecurity in LEO architectures has been addressed through a threat model specific to the space domain and the evaluation of link protection mechanisms such as SDLS/CCSDS, along with strategies for migration towards post quantum cryptography.
Finally, the project has been extended to a precision agriculture IoT case study based on LoRaWAN Direct to Satellite. The system has been dimensioned under EU868 constraints, comparing LoRa CSS and LR FHSS schemes and obtaining capacity, latency and energy autonomy results that support recommendations for high density sensor deployments in LEO constellations.
