Hello All, Can anyone here on SeeSat-L advise any significance/purpose of the "derived" epoch dates ( epoch dates where the decimal day portion equals zero--thus midnight ) released by USSPACECOM since early 1999? As an example until recently most of the NOAA birds had such an epoch date. Granted no effect on the accuracy of elsets, but I was wondering what is the impetus for the startup/continued usage of such a date for an object. I've found some 70 objects thus reported.
