Starlink relies on physics principles such as orbital mechanics, radio wave propagation, and relativity. The satellites operate in LEO, reducing signal latency compared to traditional geostationary satellites. By leveraging microwave and laser-based communication, Starlink optimizes data transmission speed. Atmospheric refraction and Doppler shifts are key challenges in maintaining signal stability, which engineers mitigate using adaptive algorithms. Additionally, the ion propulsion system utilizes Newton’s Third Law for efficient orbital adjustments. Starlink is a practical demonstration of physics applications, pushing the boundaries of space-based telecommunications.
