Definition
- Noun:
- Earth-received time: The coordinated universal time (UTC) at which a signal or event transmitted from a spacecraft or other distant source is received on Earth.
Usage
- Noun:
- ERT is recorded for all mission-critical communications.
- Scientists compared the ERT with the spacecraft's onboard clock time.
Examples
- Noun:
- The ERT for the signal's arrival was 14:30 UTC.
- Mission logs must include the precise ERT of each data transmission.
Advanced Usage
- "at ERT": At the specific Earth-received time.
- The command will be executed at the ERT specified in the plan.
- "ERT of [event]": The Earth-received time for a particular occurrence.
- Analyzing the ERT of the probe's last transmission is crucial.
Variants and Related Words
- SCET (Spacecraft Event Time): The time an event occurs according to the spacecraft's clock, often contrasted with ERT.
- UTC (Coordinated Universal Time): The primary time standard to which ERT is referenced.
Synonyms
- Earth reception time
- Ground receipt time
Notes
- ERT is a specialized acronym used primarily in space science, telecommunications, and satellite operations. It is a fixed, objective timestamp for when information reaches Earth-based tracking stations, distinct from the time the event actually occurred at the source.
Noun
