Time Transfer via Satellite

Time transfer via satellite is a method used to synchronize clocks between different locations using satellites. Highly precise atomic clocks on satellites send time signals to ground stations, allowing synchronization across vast distances. This process is essential for navigation systems like GPS, telecommunications, and scientific research, ensuring all systems operate with accurate, unified timing. Because signals travel at the speed of light, adjustments are made for the effects of the satellite’s orbit and the Earth's gravity to maintain exact synchronization between different points on Earth.
