GPS Time is a precise timekeeping system used by the Global Positioning System to provide accurate location data. It is based on atomic clocks and is measured in weeks and seconds since January 6, 1980. Unlike standard time, GPS Time does not account for leap seconds, which are added to Coordinated Universal Time (UTC) to keep it in sync with the Earth's rotation. GPS Time is crucial for various applications, including navigation, mapping, and timing services. Devices that use GPS rely on this time system to calculate distances and synchronize operations, ensuring that users receive accurate and reliable information for their location-based needs.
