Pre-Programmed Pointing Lists[edit]

The Pre-Programmed Pointing Lists (PPL) are produced by the Planck Science Office from the Baseline Scanning Strategy with the help of the Software Planning and Performance Tool. They are sent to MOC where they are used in the production of the Augmented Pre-Programmed Pointing Lists (APPL) used for commanding the spacecraft attitude.

PPLs can be found in the Planck Legacy Archive in the "Time-Ordered Information: Operational Files" section. A full list of the available files can be found here.

Detailed information about the PPL's (naming conventions, content, etc) can be found here: PPL ICD

Augmented Pre-Programmed Pointing Lists[edit]

APPLs are produced by Flight Dynamics at ESOC using pointing information (PPLs) from the Planck Science Office.

The APPLs incorporate information about the Operational Day boundaries in order to fit pointings into each OD.

APPLs are grouped and summarized by FD in the so-called APPL Summary File or APS.

These are available in the Planck Legacy Archive in the "Time-Ordered Information: Operational Files" section. A full list of the available files can be found here.

Detailed information about the APPL's (naming convention, contents, etc) can be found here: APPL Interface Control Document

Attitude History Files[edit]

The pointing history of Planck is described in the Attitude History Files (AHF) sequence. All the AHF can be found in the Planck Legacy Archive, for three different methods of computation ( AHF, DHF, GHF).

The GHF are made using refined pointing information from the Fiber Optics Gyroscope.

Available information concerning the AHF can be found here: AHF Interface Control Document

Focal plane geometry[edit]

The Spacecraft-Instrument Alignment Matrix (SIAM) contains all the geometry information for each detector of both instruments with respect to the main optical frame.

The last updated SIAM is provided in the Planck Legacy Archive in the "Time-Ordered Information: Operational Files" section and can also be downloaded here

Information about the structure of the SIAM can be found here: SIAM ICD

Orbit file[edit]

The orbit file is produced by the Flight Dynamics team at ESOC and contains the information of the Planck orbital history throughout the whole mission (since launch).

This product is available in the Planck Legacy Archive interface in the "Time-ordered information : Orbit file" section. Only one orbit file is delivered since it contains all the past information for the whole of the Planck mission.

The orbit file can be downloaded here.

Information about the structure, contents and format of the orbit file can be found in the [ ].

Orbit events file[edit]

The orbit events file .LEV is produced by the Flight Dynamics team at ESOC and contains the information of the Planck orbit events throughout the whole mission (since launch).

This product is available in the Planck Legacy Archive interface in the "Time-ordered information : Orbit events file" section. Only one orbit events file is delivered since it contains all the past information for the whole of the Planck mission.

The orbit events file can be downloaded here.

Information about the structure, contents and format of the orbit events file can be found in the [ ].

Operation Day definition is geometric visibility driven as it runs from the start of a DTCP (satellite Acquisition Of Signal) to the start of the next DTCP. Given the different ground stations and spacecraft will takes which station for how long, the OD duration varies but it is basically once a day.
