CelesTrak OMM / CSV format.tle — standard NORAD two-line element extension
What does this expect & produce?
Input — a CSV with the CelesTrak GP/OMM header
(OBJECT_NAME, OBJECT_ID, EPOCH, MEAN_MOTION, ECCENTRICITY, INCLINATION, …, NORAD_CAT_ID, …).
Get one at
celestrak.org
(choose CSV as the format).
Output — a standard NORAD two-line element file with the same name as the
input, only the extension changes (e.g. stations.csv → stations.tle).
Input — a NORAD TLE file: pairs of lines starting with 1 and
2 , optionally each preceded by a satellite-name line (the standard 3-line format). Both
2-line and 3-line files work.
Output — a CelesTrak OMM CSV (stations.tle → stations.csv)
holding exactly the precision the TLE encodes — nothing is invented. The round-trip
TLE → CSV → TLE is byte-for-byte identical.
