Galileo

Definition

Galileo is the European Union's global navigation satellite system (GNSS), providing accurate positioning, navigation, and timing services. Designed to be interoperable with other GNSS like GPS, it enhances the reliability and accuracy of location-based services. Galileo is crucial for applications ranging from autonomous vehicles to search and rescue operations, making it a significant player in the realm of satellite navigation.

5 Must Know Facts For Your Next Test

1. Galileo began deployment in 2005 and aims to have a full constellation of 30 satellites by 2020, providing high-precision positioning with an accuracy of up to one meter.
2. It operates in several frequency bands, which reduces the impact of signal interference and increases the availability of satellite signals.
3. Galileo offers unique features such as Search and Rescue (SAR) services that can detect emergency beacons and provide assistance to those in distress.
4. The system is designed with a civilian priority, ensuring that its services remain available even in times of conflict or crisis.
5. Galileo satellites are equipped with atomic clocks that provide precise timing essential for accurate positioning, improving overall navigation performance.
