General objective:
Develop a practical analysis of IoT-S technologies using HAPS constellations and VLEO satellites, showing their potential through concrete use cases and demonstrating a simple real application.
Specific objectives:
1. Investigate the technical and operational characteristics of HAPS constellations and VLEO satellites.
2. Identify and describe IoT-S use cases in key sectors such as agriculture, environmental monitoring and logistics.
3. Compare the pros and cons of these technologies in terms of cost, efficiency, coverage and scalability.
4. Develop a simple simulation or prototype that demonstrates the practical implementation of a selected use case.

Proposed use case to complement the work done in i2cat:
' Environmental monitoring: design an IoT-S system to collect air quality data in remote areas. Using virtual sensors connected to a simulated network, data would be transmitted through a simulated VLEO or HAPS constellation and displayed in a web application or basic software.
 
Overview (resum en anglès):
This project presents an autonomous environmental monitoring system that provides additional information to forest preservation teams in response to the growing threat of fires due to the effects of climate change (i.e., droughts and rising temperatures), which pose a significant risk to the region's biodiversity and ecosystems.

The solution proposes low-energy weather stations that can measure environmental variables (i.e., temperature, humidity, wind, and soil moisture). These stations are powered by solar energy systems, and data communication will be done through low-Earth-orbit (LEO) satellite communication modules, enabling them to be deployed in rural and remote areas where terrestrial network coverage is unavailable.

The prototype was developed in collaboration with the Space Communications team at i2Cat, validating the viability of non-terrestrial networks (NTNs) as a connectivity support for the Internet of Things (IoT). During the testing and deployment phases in Móra la Nova, the system successfully transmitted environmental data in real-time with an acceptable degree of reliability, despite limitations due to weather conditions, service providers, nd hardware durability.

In addition, this project aims to provide a reliable tool to support rural agents, firefighters, and conservation entities in the early detection of fire risks. Consolidating an innovative and sustainable solution for preventive fire management in natural environments.
