Satellite Defense refers to the strategies and technologies used to protect satellites from various threats, including space debris, cyberattacks, and hostile actions. As satellites play a crucial role in communication, navigation, and surveillance, ensuring their safety is vital for national security and global infrastructure. To enhance Satellite Defense, countries and organizations employ advanced tracking systems, develop resilient satellite designs, and collaborate on international regulations. These efforts aim to mitigate risks and ensure the continued functionality of satellites, which are essential for modern life, including weather forecasting, GPS navigation, and military operations.
