What is Satellite time?

Satellite time refers to the timekeeping systems used by satellites, particularly those in global navigation satellite systems (GNSS) like GPS. These systems maintain precise time to provide accurate positioning information to users on Earth. Satellite time is typically based on atomic clocks, ensuring high precision, and is synchronized with Universal Time Coordinated (UTC). This synchronization allows for consistent and reliable timing across various applications, including navigation, telecommunications, and scientific research.
