spacecraft event time การใช้

• "' June 11 "' " Cassini " flew by the moon Phoebe at 19 : 33 UT in Spacecraft Event Time at 2068 kilometers distance.
• Determining the Spacecraft Event Time involves taking the time at Earth and adding or subtracting the signal travel time, depending on whether the signal is being sent to or received from the spacecraft . For events transmitted from the spacecraft to Earth, the SCET of an event on the spacecraft can be defined as equal to the ERT ( Earth-Received Time ) minus the OWLT ( One-Way Light Time ).
