terrestrial dynamical time Sentence Examples
- Terrestrial Dynamical Time (TDT) is the fundamental time scale for geodetic and astronomical applications.
- TDT measures time as elapsed by the rotation of the Earth relative to distant stars.
- TDT is used as the reference time scale for the Global Positioning System (GPS).
- TDT is distinct from Coordinated Universal Time (UTC), which incorporates leap seconds to account for the Earth's slowing rotation.
- TDT provides a more stable and consistent time scale for precision navigation and remote sensing.
- TDT is essential for accurate positioning and timing in fields such as surveying, geodesy, and astronomy.
- TDT is defined by the rotation of the Earth and is independent of gravitational effects.
- TDT is aligned with the International Atomic Time (TAI) scale to within 20 nanoseconds.
- TDT is monitored by the International Bureau of Weights and Measures (BIPM) to ensure its accuracy and stability.
- TDT serves as a cornerstone for scientific research and practical applications that rely on precise time measurement.
