Telecommand History Files

This directory contains Telecommand History (TCH) files. These are also known as Telecommand History Files (THF).

Format/ICD

• TC history Interface Control Document, SPIRE-ICS-DOC-000900, issue 1.0, 2002-10-30.
• Herschel-Planck Mission Control System ICD: Data Disposition System, PT-CMOC-MDS-3108-OPS-GDS, issue 1.9, 2010-03-04.

Known Issues

• All CMH files have been redelivered by MOC as there were some gaps in the original files (see SCIAT-151).

• CMH for OD-309 has been corrected (see SCIAT-144).

• There is a small overlap between files for the time period 2009-05-28T10:39:05.000Z 2009-05-28T10:38:44.000Z as a result of an overlap in the PSFs (OD 14/15).

• Gap: 2013-06-17T10:52:00.000Z 2013-06-17T10:52:01.000Z # Extends 1 minutes beyond end of OD but after switch-off

• Gap: 2013-06-18T22:52:00.000Z 2013-06-17T10:52:00.000Z # Not a gap but extension beyond end of OD 1495
