What is Satellite Propulsion?

Imagine a satellite orbiting Earth, capturing high-resolution images or beaming down internet signals. Now, picture it subtly adjusting its position to avoid space debris or fine-tuning its orbit to extend its mission. How does it achieve these delicate maneuvers in the vast emptiness of space? The answer lies in satellite propulsion.

Keeping Satellite Constellations in Orbit

A satellite constellation is a group of satellites that work together to provide the Earth with services such as global internet, weather monitoring, and Earth observation. While the basic idea of a constellation is straightforward, the technology that brings these networks to life is impressively intricate. Learn about the key technical ingredients.
