Satellite Constellations

Satellite constellations refer to a group of artificial satellites that are coordinated in orbits around the Earth in such a way that they work together to provide comprehensive coverage or specific functionalities, such as communication, navigation, or Earth observation. These satellites are strategically positioned in orbits that allow them to operate in concert, often working in a synchronized manner to maintain continuous connectivity or to enhance data collection capabilities.

The arrangement typically enables the satellites to effectively cover a larger area of the Earth’s surface, reducing the possibility of service interruption. This concept is crucial for modern technologies, including global positioning systems (GPS) and satellite internet services, as it improves signal strength, reliability, and latency.

Satellite constellations can vary in scale, ranging from a few satellites to hundreds, depending on the application and required coverage area. Notable examples include the Global Positioning System (GPS), the Starlink internet service by SpaceX, and the Global Navigation Satellite System (GLONASS) of Russia.
