Module ccsds::timecode

Timecode parsing for CCSDS Space Packet data.

CCSDS Day Segmented Timecode (CDS) formats

Satellite/Sensors using this format (not a complete list!).

Mission	Satellite	Types
JPSS	SNPP	All sensors & S/C
JPSS	NOAA20	All sensors & S/C
JPSS	NOAA21	All sensors & S/C
EOS	Aqua	*MODIS (Sci & Engr)
EOS	Aqua	*CERES

• EOS GIIS packet format as documented in reference 1

CCSDS Unsegmented Timecode (CUC) Formats

The following instruments use some form of CUC format, with different number of field bits and starting at different offsets into the user data zone.

Mission	Satellite	Types	P-field len	T-Field len	Start byte
EOS	Aqua	All sensor HK	2	6	1
EOS	Aqua	Most S/C	2	6	0
EOS	Aqua	AMSU-E	1	5	1

• CUC formats are used for the EOS GIRD and S/C packet formats as documented in reference 1
