KPL/FK Mars Express Spacecraft and Beagle-2 Lander Frames Kernel ======================================================================== This frame kernel contains complete set of frame definitions for the Mars Express Spacecraft (MEX) and Beagle-2 Lander (BEAGLE2) including definitions for the MEX fixed and MEX science instrument frames and BEAGLE2 fixed, BEAGLE2 instrument, and landing site local frames. This kernel also contains NAIF ID/name mapping for the MEX and BEAGLE2 instruments. Version and Date ======================================================================== Version 1.0 -- June 16, 2008 -- Jorge Diaz del Rio, MIG Added Visual Monitoring Camera (VMC) frame. Version 0.9 -- May 21, 2008 -- J. Vazquez - Added MEX_SA+Y_ZERO and MEX_SA-Y_ZERO, fixed offset frames with respect to MEX_SPACECRAFT. - Modified MEX_SA_+Y and MEX_SA_-Y. The cells of the Solar Arrays face the +Z axis of the frames. The frames are type 3 frames that rotate with respect to MEX_SA+Y_ZERO and MEX_SA-Y_ZERO. Version 0.8 -- September 17, 2004 -- Boris Semenov, NAIF Added ASPERA_IMAS frame. This frame was introduced because it matches the "natural" IMA spherical coordinate system and the way IMA operates better than the ASPERA_IMA frame defined originally (see the latest ASPERA IK file for more discussion on this issue.) Version 0.7 -- July 19, 2004 -- Boris Semenov, NAIF Corrected HGA frame to incorporate 5 degree boresight offset towards +Z. Version 0.6 -- March 15, 2004 -- Boris Semenov, NAIF Incorporated revised OMEGA frame layout (no OMEGA_BASE and OMEGA_SWIR frames, OMEGA_SWIR_S defined w.r.t. SPACECRAFT, OMEGA_SWIR_L and OMEGA_VNIR defined w.r.t OMEGA_SWIR_S) and initial in-flight calibrated alignments provided by Nicolas Manaud on March 12, 2004. Renamed OMEGA_SWIR_S to OMEGA_SWIR_C for consistency with the conventions accepted by OMEGA team. Version 0.5 -- December 15, 2003 -- Boris Semenov, NAIF Incorporated in-flight calibrated alignments provided by Thomas Roatsch on December 15, 2003 into the HRSC_HEAD and HRSC_SRC frame definitions. Renamed and re-defined ASPERA Solar Sensor frames, MEX_ASPERA_SS1 and MEX_ASPERA_SS2. Version 0.4 -- October 5, 2003 -- Boris Semenov, NAIF Modified ASPERA frames to match the conventions accepted by the ASPERA team, specifically: -- changed MEX_ASPERA_BASE frame name to MEX_ASPERA_URF -- changed MEX_ASPERA_SCANNER frame name to MEX_ASPERA_SAF -- replaced MEX_ASPERA_NPD frame with MEX_ASPERA_NPD1 and MEX_ASPERA_NPD2 -- added MEX_ASPERA_IMA_URF frame (in the IMA branch between MEX_SPACECRAFT and MEX_ASPERA_IMA frames) -- added MEX_ASPERA_SS0 and MEX_ASPERA_SS1 frames Updated ASPERA frame tree diagrams and descriptions accordingly Modified MEX_HRSC_SRC frame to incorporate 90 degree rotation w.r.t to the MEX_HRSC_BASE frame (per HRSC calibration results) Updated BEAGLE2_LOCAL_LEVEL frame to correspond to the project official landing site coordinates (areocentric LON=90.75 & LAT=11.6) Version 0.3 -- June 2, 2003 -- Boris Semenov, NAIF Changed the types of and relationship between the MEX_SPACECRAFT (mechanical) and MEX_SC_REF (ACS reference) frames. Now the MEX_SC_REF frame is CK-based because telemetry and s/c CKs contains orientation for it and the MEX_SPACECRAFT frame is fixed offset (rotated by 180 about Z) with respect to MEX_SC_REF. Version 0.2 -- January 2, 2002 -- Boris Semenov, NAIF Added frames and IDs for the short and long wavelength OMEGA SWIR channels per review feedback from Yves Langevin, OMEGA Team (December 2001.) Version 0.1 -- December 5, 2001 -- Boris Semenov, NAIF Updated SPICAM frames per review feedback from Emmanuel Dimarellis (e-mail from November 11, 2001.) Version 0.0 -- June 18, 2001 -- Boris Semenov, NAIF Preliminary Version. Pending review and approval by MEX and BEAGLE2 instrument teams and ESOC Science operations team.

V Individual instrument frame trees are provided in the corresponding sections of this file MEX Spacecraft and Spacecraft Structures Frames ======================================================================== This section of the file contains the definitions of the spacecraft and spacecraft structures frames. MEX Spacecraft Frames -------------------------------------- Two reference frames are defined for the MEX spacecraft (see [6]) -- "mechanical/structure frame" (Xb,Yb,Zb) and "spacecraft reference frame" (Xa,Ya,Za). The "mechanical/structure frame" frame (Xb,Yb,Zb), with respect to which orientation of all science instruments and spacecraft structures is defined, is called MEX_SPACECRAFT frame in the MEX SPICE implementation. This frame is defined as follows: - the payloads are located on the +Zb axis (the Main Engine being on the -Zb axis); - the HGA is located on -Xb axis; - the +Y axis is defined so that the (Xb,Yb,Zb) frame is right- handed. - the origin of this frames is the launch vehicle interface point. The "spacecraft reference frame" (Xa,Ya,Za) frame, used primarily in AOSC studies, is the one for which orientation is determined on-board the spacecraft. This frame is called MEX_SC_REF in MEX SPICE implementation. This frame is related to MEX_SPACECRAFT frame (Xb,Yb,Zb) as a follows: - +Xa = -Xb; - +Ya = -Yb; - +Za = Zb ; - the origin of this frame is also located at the launch vehicle interface point.

Since the orientation of the MEX_SC_REF frame is computed on-board, sent down in telemetry, and stored in the s/c CK files, it is defined as a CK-based frame. The MEX_SPACECRAFT frame is then defined as a fixed-offset frame -- rotated by 180 degrees about +Z axis -- with respect to the MEX_SC_REF frame. These sets of keywords define the MEX_SPACECRAFT and MEX_SC_REF frames: \begindata FRAME_MEX_SPACECRAFT = -41000 FRAME_-41000_NAME = 'MEX_SPACECRAFT' FRAME_-41000_CLASS = 4 FRAME_-41000_CLASS_ID = -41000 FRAME_-41000_CENTER = -41 TKFRAME_-41000_RELATIVE = 'MEX_SC_REF' TKFRAME_-41000_SPEC = 'ANGLES' TKFRAME_-41000_UNITS = 'DEGREES' TKFRAME_-41000_AXES = ( 1, 2, 3 ) TKFRAME_-41000_ANGLES = ( 0.0, 0.0, 180.0 ) FRAME_MEX_SC_REF = -41001 FRAME_-41001_NAME = 'MEX_SC_REF' FRAME_-41001_CLASS = 3 FRAME_-41001_CLASS_ID = -41001 FRAME_-41001_CENTER = -41 CK_-41001_SCLK = -41 CK_-41001_SPK = -41 \begintext MEX Solar Array Frames -------------------------------------- Note that, unlike in most spacecrafts, the +Y panel is situated along the -Y axis of the MEX_SPACECRAFT frame, and the -Y panel is situated along the +Y axis. The reason is that the solar arrays are named with respect to the MEX_SC_REF frame. Two auxiliary frames, MEX_SA+Y_ZERO and MEX_SA-Y_ZERO, fixed with respect to the MEX_SPACECRAFT frame, are defined as follows: - +Y is parallel to the longest side of the array, positively orientated from the yoke to the end of the wing. - +Z is orientated along the -X axis of MEX_SPACECRAFT. It is equal to the -X axis of MEX_SPACECRAFT. - +X is defined such that (X,Y,Z) is right handed. Since the MEX solar arrays can be articulated (having one degree of freedom), the solar Array frames, MEX_SA+Y and MEX_SA-Y, are defined as CK frames with their orientation given relative to MEX_SA+Y_ZERO and MEX_SA-Y_ZERO. Both array frames are defined as follows (from [6]): - +Y is parallel to the longest side of the array, positively oriented from the yoke to the end of the wing; - +Z is normal to the solar array plane, the solar cells facing +Z; - +X is defined such that (X,Y,Z) is right handed; - the origin of the frame is located at the yoke geometric center. The axis of rotation is parallel to the Y axis of the spacecraft and solar array frames.

Therefore, the frame associated with it -- the ASPERA main unit reference frame, MEX_ASPERA_URF, -- is a fixed offset frame with its orientation given relative to the MEX_SPACECRAFT frame. The MEX_ASPERA_URF frame is defined as follows: - +Z axis is along the scanner rotation axis and points from the main unit mounting plate toward the scanner (nominally this axis is co-aligned with the s/c +Z axis); - +X axis is parallel to the longer side of the main unit base and points from the NPD side towards the ELS side for scanner in "90 degrees" position (nominally this axis is co-aligned with the s/c -Y axis); - +Y completes the right handed frame; - the origin of the frame is located at the intersection of the mounting surface of the main unit base and the axis of the mounting screw hole located at NPD2 side for scanner in "90 degrees" position. Nominally this frame is rotated by -90 degrees about Z axis from the s/c frame. Since ASPERA main unit scanner rotates with respect to its base with 0..180 angle range clockwise about Z axis of the MEX_ASPERA_URF frame, the frame associated with it -- the sensor assembly frame, MEX_ASPERA_SAF, -- is defined as a CK frame with its orientation provided in a CK file relative to the MEX_ASPERA_URF frame. The MEX_ASPERA_SAF frame is defined as follows: - +Z axis is along the scanner rotation axis and points from the main unit mounting plate toward the scanner; this axis is co-aligned with the +Z axis of the MEX_ASPERA_URF frame; - +X axis is along the ASPERA sensor assembly central axis and points from the NPD sensor towards the ELS sensor; this axis is co-aligned with the +X axis of the MEX_ASPERA_URF frame when scanner is in "90 degrees" position. - +Y axis completes the right handed frame; - the origin of the MEX_ASPERA_SAF frame is located at the intersection of the scanner rotation axis and the bottom (mounting) surface of the scanner base.

ELS and NPI sensor frames are defined such that their axes are co-aligned with the axes of the MEX_ASPERA_SAF frame and their origins are at the sensors' "focal points", located at the intersection of the sensor's aperture plane and the sensor's symmetry axis.

The origins of these frames are at the sensor "focal points", which are located in the sensor's aperture plane at the point here the sensor sector view directions intersect.

Therefore, the PFS base frame, MEX_PFS_BASE, is a fixed offset frame with its orientation given relative to the MEX_SPACECRAFT frame. The MEX_PFS_BASE frame is defined by the instrument design and its mounting on the s/c as follows: - +Y axis is along the nominal PFS 'S' module scanner rotation axis and nominal PFS 'O' module optical axis, and points from the PFS 'S' module toward the PFS 'O' module; nominally this axis is co-aligned with the s/c +Y axis; - +Z axis is parallel to the nominal direction of the PFS 'S' scanner boresight in its 'nadir' (zero) position; it nominally points in the same direction as the s/c +Z axis; - +X completes the right hand frame; it nominally points in the same direction as the s/c +X axis; - the origin of this frame is located at the intersection of the PFS 'S' scanner rotation axis and the scanner cylinder central axis. Nominally this frame is co-aligned with the s/c frame. Any misalignment between nominal and actual PFS mounting alignment measured pre-launch can be incorporated into the definition of this frame. Since the PFS 'S' scanner rotates with respect to its base, the MEX_PFS_SCANNER frame is defined as a CK frame with its orientation provided in a CK file relative to the MEX_PFS_BASE frame. The MEX_PFS_SCANNER frame is defined as follows: - +Y axis is along the nominal PFS 'S' module scanner rotation axis and nominal PFS 'O' module optical axis, and points from the PFS 'S' module toward PFS 'O' module; nominally this axis is co-aligned with the +Y axis of the MEX_PFS_BASE frame; - +Z axis is parallel to the PFS 'S' scanner boresight; in 'nadir' scanner position it is co-aligned with the +Z axis of the MEX_PFS_BASE frame; - +X completes the right hand frame; - the origin of this frame is located at the intersection of the PFS 'S' scanner rotation axis and the scanner central axis. For an arbitrary scanner angle, the MEX_PFS_SCANNER frame is rotated by this angle about the +Y axis with respect to the MEX_PFS_BASE frame. This diagram illustrates the MEX_PFS_BASE and MEX_PFS_SCANNER frames for scanner angles of +25 degrees ('25 left') and -25 degrees ('25 right').

Each of these 'fixed-scanner-position' convenience frames is defined as a fixed offset frame with respect to the MEX_PFS_BASE frame as follows: - +Y axis is along the nominal PFS 'S' module scanner rotation axis and nominal PFS 'O' module optical axis, and points from the PFS 'S' module toward PFS 'O' module; nominally this axis is co-aligned with the +Y axis of the MEX_PFS_BASE frame; - +Z axis is parallel to the PFS 'S' scanner boresight at a particular angle; - +X completes the right hand frame; - the origin of this frame is located at the intersection of the PFS 'S' scanner rotation axis and scanner central axis.

Since the SPICE frames subsystem calls for specifying the reverse transformation--going from the instrument or structure frame to the base frame--as compared to the description given above, the order of rotations assigned to the TKFRAME_*_AXES keyword is also reversed compared to the above text, and the signs associated with the rotation angles assigned to the TKFRAME_*_ANGLES keyword are the opposite from what is written in the above text. \begindata FRAME_MEX_SPICAM_SIR = -41610 FRAME_-41610_NAME = 'MEX_SPICAM_SIR' FRAME_-41610_CLASS = 4 FRAME_-41610_CLASS_ID = -41610 FRAME_-41610_CENTER = -41 TKFRAME_-41610_RELATIVE = 'MEX_SPICAM_BASE' TKFRAME_-41610_SPEC = 'ANGLES' TKFRAME_-41610_UNITS = 'DEGREES' TKFRAME_-41610_AXES = ( 1, 2, 3 ) TKFRAME_-41610_ANGLES = ( 0.0, 0.0, 0.0 ) FRAME_MEX_SPICAM_SUV = -41620 FRAME_-41620_NAME = 'MEX_SPICAM_SUV' FRAME_-41620_CLASS = 4 FRAME_-41620_CLASS_ID = -41620 FRAME_-41620_CENTER = -41 TKFRAME_-41620_RELATIVE = 'MEX_SPICAM_BASE' TKFRAME_-41620_SPEC = 'ANGLES' TKFRAME_-41620_UNITS = 'DEGREES' TKFRAME_-41620_AXES = ( 1, 2, 3 ) TKFRAME_-41620_ANGLES = ( 0.0, 0.0, 0.0 ) FRAME_MEX_SPICAM_SIR_SOLAR = -41611 FRAME_-41611_NAME = 'MEX_SPICAM_SIR_SOLAR' FRAME_-41611_CLASS = 4 FRAME_-41611_CLASS_ID = -41611 FRAME_-41611_CENTER = -41 TKFRAME_-41611_RELATIVE = 'MEX_SPICAM_BASE' TKFRAME_-41611_SPEC = 'ANGLES' TKFRAME_-41611_UNITS = 'DEGREES' TKFRAME_-41611_AXES = ( 3, 2, 1 ) TKFRAME_-41611_ANGLES = ( 0.0, 90.0, -30.0 ) FRAME_MEX_SPICAM_SUV_SOLAR = -41621 FRAME_-41621_NAME = 'MEX_SPICAM_SUV_SOLAR' FRAME_-41621_CLASS = 4 FRAME_-41621_CLASS_ID = -41621 FRAME_-41621_CENTER = -41 TKFRAME_-41621_RELATIVE = 'MEX_SPICAM_BASE' TKFRAME_-41621_SPEC = 'ANGLES' TKFRAME_-41621_UNITS = 'DEGREES' TKFRAME_-41621_AXES = ( 3, 2, 1 ) TKFRAME_-41621_ANGLES = ( 0.0, 90.0, -30.0 ) \begintext BEAGLE2 Frames ======================================================================== This section of the file contains the definitions of the Beagle-2 local level, lander and instrument frames.

The target Beagle-2 landing site selected on December 20, 2000 is located at: 270.0 degrees west planetographic longitude, and 10.6 degrees north planetographic latitude which is in Isidis Basin of Utopia Planitia. More accurate coordinates used by the project during summer/fall 2003 are: 269.250 degrees west planetographic longitude, and 11.734 degrees north planetographic latitude The transformation from 'BEAGLE2_LOCAL_LEVEL' frame to 'IAU_MARS' frame is a 3-2-3 rotation with angles defined as the negative of the site longitude, the negative of the site colatitude, 180 degrees. \begindata FRAME_BEAGLE2_LOCAL_LEVEL = -44900 FRAME_-44900_NAME = 'BEAGLE2_LOCAL_LEVEL' FRAME_-44900_CLASS = 4 FRAME_-44900_CLASS_ID = -44900 FRAME_-44900_CENTER = -44 TKFRAME_-44900_RELATIVE = 'IAU_MARS' TKFRAME_-44900_SPEC = 'ANGLES' TKFRAME_-44900_UNITS = 'DEGREES' TKFRAME_-44900_AXES = ( 3, 2, 3 ) TKFRAME_-44900_ANGLES = ( 269.250, -78.266, 180.0 ) \begintext Beagle-2 Lander Frame -------------------------------------- The BEAGLE2 lander frame, BEAGLE2_LANDER, is defined by the lander design as follows: - +Z axis is parallel to the lander capsule symmetry axis and points up; - +X axis point from +Z toward robotic arm; - +Y axis completes the right hand frame; - the origin of the frame is located at the intersection of the lander main capsule outer rim plane and the lander main capsule symmetry axis. Once landed the lander orientation is constant with respect to the surface and, therefore, this frame is defined as a fixed-offset frame with its orientation provided with respect to the BEAGLE2_LOCAL_LEVEL frame. Should the lander orientation change due to sliding and/or science instrument operations, BEAGLE2_LANDER frame should be re-defined as a CK based frame. For nominal applications, the BEAGLE2_LANDER frame is assumed to be co-aligned with the BEAGLE2_LOCAL_LEVEL frame. \begindata FRAME_BEAGLE2_LANDER = -44000 FRAME_-44000_NAME = 'BEAGLE2_LANDER' FRAME_-44000_CLASS = 4 FRAME_-44000_CLASS_ID = -44000 FRAME_-44000_CENTER = -44 TKFRAME_-44000_RELATIVE = 'BEAGLE2_LOCAL_LEVEL' TKFRAME_-44000_SPEC = 'ANGLES' TKFRAME_-44000_UNITS = 'DEGREES' TKFRAME_-44000_AXES = ( 1, 2, 3 ) TKFRAME_-44000_ANGLES = ( 0.0, 0.0, 0.0 ) \begintext Beagle-2 Instrument Frames -------------------------------------- Beagle-2 instrument frames are TDB.
