Convert from Terrestrial time to Barycentric Dynamical Time (TDB) Julian date
Estimate Julian Date for Barycentric Dynamical Time
Estimate the Julian date for the Barycentric Dynamical Time for the Terrestrial Time 2014/10/15 16:22:31.
jdtdb = tdbjuliandate([2014,10,15,16,22,31])
jdtdb = 2.4569e+06
Estimate Julian Dates for the Barycentric Dynamical Time and TT-TDB
Estimate the Julian dates for the Barycentric Dynamical Time and TT-TDB in seconds for the terrestrial time 2014/10/15 16:22:31 and 2010/7/22 1:57:17.
[jdtdb,tttdb] = tdbjuliandate([2014,10,15,16,22,31;2010,7,22,1,57,17])
JDTDB = 1.0e+06 * 2.4569 2.4554 TTTTDB = 0.0016 0.0005
terrestrial_time — Terrestrial Time
1-by-6 array | M-by-6 array
Terrestrial Time (TT) in year, month, day, hour, minutes, and seconds for which the function calculates the Julian date for Barycentric Dynamical Time. M is the number of Julian dates, one for each TT date. Specify values for year, month, day, hour, and minutes as whole numbers.
jdtdb — Julian date
Julian date for the Barycentric Dynamical Time, returned as an M-by-1 array. M is the number of rows, one for each Terrestrial Time input.
tttdb — Difference in seconds
Difference in seconds between Terrestrial Time and Barycentric Dynamical Time (TT-TDB), returned as an M-by-1 array. M is the number of rows, one for each Terrestrial Time input.
Fundamentals of Astrodynamics and Applications indicates an accuracy of 50 microseconds, which this function cannot achieve due to numerical issues with the values involved.
