Student Guide (IB Design Technology)

Simple Explanation: New satellite systems in low Earth orbit are growing fast, but we need to make sure they are safe from hackers and won't break easily, otherwise, people won't trust or use them.

Why This Matters: Understanding the security and reliability of complex systems like LEO satellites is vital for designing products that are not only functional but also safe and dependable for users.

Critical Thinking: How might the increasing commercialization and 'mega-constellation' trend in LEO satellites exacerbate existing security and reliability issues, and what novel design approaches could mitigate these amplified risks?

IA-Ready Paragraph: The rapid advancement of Low Earth Orbit (LEO) satellite communication systems, driven by increasing user demand and technological progress, necessitates a critical focus on their security and reliability. As highlighted by Yue et al. (2023), the inherent characteristics of LEO SCSs present unique vulnerabilities to cyber-attacks and operational risks. Therefore, any design project involving LEO technology must proactively address these challenges by integrating robust security frameworks and ensuring system resilience to guarantee commercial viability and user trust.
