Spacecraft On-Board ephemeris data/orbit files to be read via SDP Toolkit, Binary Format
Entry ID: AM1EPHN0


Summary
Abstract: AM1EPHN0 is the Terra 2-hour spacecraft ephemeris data file in native format. The file name format is the following:
AM1EPHN0.Ayyyyddd.hhmm.vvv.yyyydddhhmmss where from left to right: 0 = Spacecraft Level 0; N = Native format; EPH = Ephemeris; AM1 = Satellite (Terra); yyyy = data year, ddd = Julian data day, hh = data hour, mm = data minute; vvv = Version ID; yyyy = production year, ddd = Julian production day, hh = production hour, mm = production minute, and ss = production second.

Quality
Overall NRT products match to operational with some expected minor differences from use of different ancillaries and ephemeris. There aren?t any data gaps or data artifacts.
