KPL/FK Dawn Frames Kernel ======================================================================== This frame kernel contains complete set of frame definitions for the Dawn Spacecraft (DAWN) including definitions for the Dawn spacecraft and Dawn science instrument and engineering structure frames. This kernel also contains NAIF ID/name mapping for the Dawn instruments. Version and Date ======================================================================== Version 1.4 -- March 29, 2018 -- Boris Semenov, NAIF Added DSK surface name-ID mapping section. Version 1.3 -- April 6, 2016 -- Boris Semenov, NAIF Redefined the DAWN_FC2 frame as a CK-based frame to facilitate providing different FC2 alignments relative to the s/c frame for Vesta and Ceres missions. Version 1.2 -- October 29, 2012 -- Boris Semenov, NAIF Added Euler dynamic frames for Vesta coordinate systems ``IAU-2000'' and ``DAWN-Claudia''. Version 1.1 -- July 5, 2011 -- Boris Semenov, NAIF Corrected description of the FC1 and FC2 frames. All frame definitions are identical to Version 1.0. Version 1.0 -- March 21, 2011 -- Boris Semenov, NAIF Incorporated updated definitions of the DAWN_VIR_VIS, DAWN_VIR_IR, DAWN_VIR_VIS_ZERO, and DAWN_VIR_IR_ZERO frames provided by by Dr. Federico Tosi, INAF in "dawn_v10_draft3.tf" Changed IDs of DAWN_VIR_VIS_ZERO and DAWN_VIR_IR_ZERO frames from -203212 and -203214 to -203221 and -203223 to eliminate confusion that may result from the IDs -203212 and -203214 mapping to different names in the frames and physical objects domains. Since these frames are fixed-offset, class 4 frames that are referred to only by name in SPICE API calls and other kernels (e.g. IKs) this change should be transparent to the users of this FK. Updated star tracker alignments (frames DAWN_ST1 and DAWN_ST2) and FC alignments (frames DAWN_FC1 and DAWN_FC2) per MCR-111570. Version 0.9 -- July 1, 2010 -- Boris Semenov, NAIF Incorporated updated definitions of the DAWN_VIR_VIS, DAWN_VIR_IR, DAWN_VIR_VIS_ZERO, and DAWN_VIR_IR_ZERO frames provided by Eleonora Ammannito, INAF in "VIR_kernel_update_r2.doc". Version 0.8 -- October 8, 2009 -- Dr. Federico Tosi, INAF - IFSI Boris Semenov, NAIF Redefined VIR frames to better encapsulate the instrument scan mirror motion and optical path misalignments, specifically: - added DAWN_VIR frame (-203200), fixed to the spacecraft, to capture the instrument base alignment relative to the spacecraft - added DAWN_VIR_SCAN frame (-203201), CK-based, to capture the motion of the mirror - changed the reference frame for DAWN_VIR_VIS and DAWN_VIR_IR to DAWN_VIR_SCAN - renamed DAWN_VIR_VIS_SCAN and DAWN_VIR_IR_SCAN to DAWN_VIR_VIS_ZERO and DAWN_VIR_IR_ZERO while keeping the same IDs (-203212 and -203214) and redefined them to be fixed offset frames relative to DAWN_VIR - added DAWN_VIR/-203200 and DAWN_VIR_SCAN/-203201 name/ID mappings Version 0.7 -- July 3, 2009 -- Boris Semenov, NAIF Incorporated Thomas Roatsch's name/ID mappings and individual frames for FC filters. Included FC alignments used by DLR to process MGA data in the comments. Corrected and completed comments in the "Dawn Mission NAIF ID Codes -- Summary Section" section. Re-worded some of the version section entries for clarity. Version 0.6t2 -- June 23, 2009 -- Steven Joy, DSC Propagated test version of the DAWN_VIR_VIS_96/-203218 and DAWN_VIR_VIS_32/-203219 name/ID mapping. Neither this nor the previous updates have still been reviewed by the VIR team. Version 0.6t -- April 09, 2009 -- Steven Joy, DSC Propagated test version of the DAWN_VIR_VIS_16/-203217 name/ID mapping. Neither this nor the previous updates have still been reviewed by the VIR team. Version 0.6t -- Jan 12, 2009 -- Steven Joy, DSC Propagated test version of the DAWN_VIR_VIS_124/-203215 and DAWN_VIR_VIS_64/-203216 name/ID mappings from version 0.5t into the version 0.6 released by Boris.

V Individual instrument frame trees are provided in the other sections of this file Dawn Target Frames ======================================================================== This section of the file contains the body-fixed frame definitions for the Dawn mission targets -- asteroids 4 Vesta and 1 Ceres. All target body-fixed frames are defined according to the standard body-fixed frame formation rules: - +Z axis is toward the North pole; - +X axis is toward the prime meridian; - +Y axis completes the right handed frame; - the origin of this frame is at the center of the body. Some of these frames are defined as PCK-based frames with the orientation computed by evaluating corresponding rotation constants provided in the PCK file(s). Other frames are defined as Euler frames with the constants equivalent to the PCK constants included directly into the frame definition. Vesta Frames -------------------------------------- ``IAU_VESTA'' Frame The IAU_VESTA frame is a PCK-based Vesta body-fixed frame built into the SPICE Toolkit starting with the Toolkit version N0064 (June 2010). Its orientation is computed using Vesta rotation constants from the last loaded PCK file containing such constants. ``VESTA_FIXED'' Frame The VESTA_FIXED frame is a PCK-based Vesta body-fixed frame defined in a separate FK (per request from SOA team on May 9, 2005). This frame is a synonym of the IAU_VESTA frame. Its orientation is computed using Vesta rotation constants from the last loaded PCK file containing such constants. ``IAU-2000'' Frame The VESTA_IAU_2000 frame represents the ``IAU-2000'' coordinate system used by the project prior to its arrival to Vesta as well as in numerous pre-DAWN ground observations of Vesta. It is defined as an Euler frame mathematically identical to the PCK frame IAU_VESTA when the IAU_VESTA frame is used with the rotation constants from the DAWN PCK file ``pck00008.tpc''. The ``pck00008.tpc'' PCK data defining the ``IAU-2000'' coordinate system orientation are: BODY2000004_POLE_RA = ( 301. 0. 0. ) BODY2000004_POLE_DEC = ( 41. 0. 0. ) BODY2000004_PM = ( 292. 1617.332776 0. ) According to the section ``Example of an Euler Frame'' of [1] the angles for the Euler frame relative to the J2000 frame with the reference epoch of J2000 TDB are derived from the standard set of text PCK body orientation terms as follows: ANGLE_1 = -pi/2 - RA ANGLE_2 = -pi/2 + Dec ANGLE_3 = - PM The definition below incorporates the angles derived in this way from the ``IAU-2000'' coordinate system orientation constants above, in degrees with with the PM rate term converted to degrees/sec. \begindata FRAME_VESTA_IAU_2000 = -203911 FRAME_-203911_NAME = 'VESTA_IAU_2000' FRAME_-203911_CLASS = 5 FRAME_-203911_CLASS_ID = -203911 FRAME_-203911_CENTER = 2000004 FRAME_-203911_RELATIVE = 'J2000' FRAME_-203911_DEF_STYLE = 'PARAMETERIZED' FRAME_-203911_FAMILY = 'EULER' FRAME_-203911_EPOCH = @2000-JAN-01/12:00:00 FRAME_-203911_AXES = ( 3 1 3 ) FRAME_-203911_UNITS = 'DEGREES' FRAME_-203911_ANGLE_1_COEFFS = ( -31.00 ) FRAME_-203911_ANGLE_2_COEFFS = ( -49.00 ) FRAME_-203911_ANGLE_3_COEFFS = ( -292.00, -0.18719129351851851E-01 ) \begintext ``DAWN-Claudia'' Frame The DAWN_CLAUDIA frame represents the ``DAWN-Claudia'' coordinate system used by the project during operations at Vesta. It is defined as an Euler frame mathematically identical to the PCK frame IAU_VESTA when the IAU_VESTA frame is used with the rotation constants from the DAWN PCK file ``dawn_vesta_v04.tpc''. The ``dawn_vesta_v04.tpc'' PCK data defining the ``DAWN-Claudia'' coordinate system orientation are: BODY2000004_POLE_RA = ( 309.031 0.0 0.0 ) BODY2000004_POLE_DEC = ( 42.235 0.0 0.0 ) BODY2000004_PM = ( 75.39 1617.3329428 0.0 ) According to the section ``Example of an Euler Frame'' of [1] the angles for the Euler frame relative to the J2000 frame with the reference epoch of J2000 TDB are derived from the standard set of text PCK body orientation terms as follows: ANGLE_1 = -pi/2 - RA ANGLE_2 = -pi/2 + Dec ANGLE_3 = - PM The definition below incorporates the angles derived in this way from the ``DAWN-Claudia'' coordinate system orientation constants above, in degrees with with the PM rate term converted to degrees/sec. \begindata FRAME_DAWN_CLAUDIA = -203912 FRAME_-203912_NAME = 'DAWN_CLAUDIA' FRAME_-203912_CLASS = 5 FRAME_-203912_CLASS_ID = -203912 FRAME_-203912_CENTER = 2000004 FRAME_-203912_RELATIVE = 'J2000' FRAME_-203912_DEF_STYLE = 'PARAMETERIZED' FRAME_-203912_FAMILY = 'EULER' FRAME_-203912_EPOCH = @2000-JAN-01/12:00:00 FRAME_-203912_AXES = ( 3 1 3 ) FRAME_-203912_UNITS = 'DEGREES' FRAME_-203912_ANGLE_1_COEFFS = ( -39.031 ) FRAME_-203912_ANGLE_2_COEFFS = ( -47.765 ) FRAME_-203912_ANGLE_3_COEFFS = ( -75.39, -0.18719131282407406E-01 ) \begintext Dawn Spacecraft and Spacecraft Structures Frames ======================================================================== This section of the file contains the definitions of the spacecraft and spacecraft structures frames. Dawn Spacecraft Frame -------------------------------------- The Dawn spacecraft frame is defined as follows: - +Z axis is along the nominal boresight direction of the framing cameras; - +X axis is along the nominal boresight direction of the HGA; - +Y axis completes the right-hand frame; - the origin of this frame is the launch vehicle interface point.

Both array frames are defined as follows (from [5]): - +Y axis is parallel to the longest side of the array, positively oriented from the yoke to the end of the wing; - +Z axis is normal to the solar array plane, the solar cells facing +Z; - +X axis 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.

All three LGAs are rigidly attached to the s/c bus. Therefore, their frames -- DAWN_LGA+Z, DAWN_LGA+X, and DAWN_LGA-Z -- are defined as a fixed offset frames with orientation given relative to the DAWN_SPACECRAFT frame. Each of the DAWN LGA frames - DAWN_LGA+Z, DAWN_LGA+X, and DAWN_LGA-Z -- is defined as follows: - +Z axis is in the antenna boresight direction; - +Y axis is nominally parallel to the s/c +Y axis; - +X axis completes the right handed frame; - the origin of the frame is located at the geometric center of the LGA outer patch.

It is intended to capture the instrument base and scan mirror rotation axis alignment relative to the spacecraft. - the reflected scan mirror view direction frame -- DAWN_VIR_SCAN (ID -203201) -- is defined as a CK-based frame with its orientation provided in CK files relative to the DAWN_VIR frame. It is intended to capture change in the instrument view direction due to the scan mirror motion. - the reflected instrument detector view frames -- DAWN_VIR_VIS (ID -203211) and DAWN_VIR_IR (ID -203213) -- are defined as fixed offset frames relative to the DAWN_VIR_SCAN frame. They are intended to capture reflected instrument boresights and detector misalignments at any scan mirror position. - the non-moving instrument detector view frames -- DAWN_VIR_VIS_ZERO (ID -203221) and DAWN_VIR_IR_ZERO (ID -203223) -- are defined as fixed offset frames relative to the DAWN_VIR frame. They are intended to capture instrument boresights and detector misalignments at the "0" scan mirror position and are used for defining FOVs corresponding the full (256-step) and partial (128-, 64-, 16-, 96-, and 32-step) scan mirror sweeps. The +Y axes of the base and scan mirror frames (DAWN_VIR and DAWN_VIR_SCAN) are co-aligned with the scan mirror rotation axis. The +Z axes of the reflected and non-moving instrument detector view frames are in the direction of the instrument boresight at any (for DAWN_VIR_VIS and DAWN_VIR_IR) or the "0" (for DAWN_VIR_VIS_ZERO and DAWN_VIR_IR_ZERO) scan mirror position. The +Y axes of these frames are in the direction of spatial resolution and the +X axes complete the right-handed frames. Nominally, at the "0" scan mirror position all VIR frames are co-aligned with each other and with the s/c frame as shown on this diagram: +Z s/c side (science deck side) view: ------------------------------------- o-----> +Yvir* ._____|_______. | | | +Xvir*| | | V +Ysc o==/ /==================o | o----->|o==================/ /==o -Y Solar Array | | | +Y Solar Array | | | .______|______. .--V +Xsc HGA .' `. /___________\ `.|.' +Zsc and +Zvir* are out of the page The keywords below define the VIR frames. In this version of the FK all misalignments are set be zero. Preliminary alignment data for VIR-VIS indicate that the instrument boresight (center pixel view direction) is tilted with respect to the spacecraft +Z axis by 1.50 milliradians toward -Y axis and 1.25 milliradians toward +X. This misalignment is incorporated as a two rotations, first by +1.50 milliradians about +X axis and then by +1.25 milliradians about +Y axis, into the definitions of the DAWN_VIR_VIS and DAWN_VIR_VIS_ZERO frames. Preliminary alignment data for VIR-IR indicate that the instrument boresight (center pixel view direction) is tilted with respect to the spacecraft +Z axis by 0.75 milliradians toward -Y axis and 1.50 milliradians toward +X. This misalignment is incorporated as a two rotations, first by +0.75 milliradians about +X axis and then by +1.50 milliradians about +Y axis, into the definitions of the DAWN_VIR_IR and DAWN_VIR_IR_ZERO frames. \begindata FRAME_DAWN_VIR = -203200 FRAME_-203200_NAME = 'DAWN_VIR' FRAME_-203200_CLASS = 4 FRAME_-203200_CLASS_ID = -203200 FRAME_-203200_CENTER = -203 TKFRAME_-203200_RELATIVE = 'DAWN_SPACECRAFT' TKFRAME_-203200_SPEC = 'ANGLES' TKFRAME_-203200_UNITS = 'DEGREES' TKFRAME_-203200_ANGLES = ( 0.0, 0.0, 0.0 ) TKFRAME_-203200_AXES = ( 1, 2, 3 ) FRAME_DAWN_VIR_SCAN = -203201 FRAME_-203201_NAME = 'DAWN_VIR_SCAN' FRAME_-203201_CLASS = 3 FRAME_-203201_CLASS_ID = -203201 FRAME_-203201_CENTER = -203 CK_-203201_SCLK = -203 CK_-203201_SPK = -203 FRAME_DAWN_VIR_VIS = -203211 FRAME_-203211_NAME = 'DAWN_VIR_VIS' FRAME_-203211_CLASS = 4 FRAME_-203211_CLASS_ID = -203211 FRAME_-203211_CENTER = -203 TKFRAME_-203211_RELATIVE = 'DAWN_VIR_SCAN' TKFRAME_-203211_SPEC = 'ANGLES' TKFRAME_-203211_UNITS = 'DEGREES' TKFRAME_-203211_ANGLES = (-0.085943669, -0.071619724, 0.0) TKFRAME_-203211_AXES = ( 1, 2, 3 ) FRAME_DAWN_VIR_IR = -203213 FRAME_-203213_NAME = 'DAWN_VIR_IR' FRAME_-203213_CLASS = 4 FRAME_-203213_CLASS_ID = -203213 FRAME_-203213_CENTER = -203 TKFRAME_-203213_RELATIVE = 'DAWN_VIR_SCAN' TKFRAME_-203213_SPEC = 'ANGLES' TKFRAME_-203213_UNITS = 'DEGREES' TKFRAME_-203213_ANGLES = (-0.042971835, -0.085943669, 0.0) TKFRAME_-203213_AXES = ( 1, 2, 3 ) FRAME_DAWN_VIR_VIS_ZERO = -203221 FRAME_-203221_NAME = 'DAWN_VIR_VIS_ZERO' FRAME_-203221_CLASS = 4 FRAME_-203221_CLASS_ID = -203221 FRAME_-203221_CENTER = -203 TKFRAME_-203221_RELATIVE = 'DAWN_VIR' TKFRAME_-203221_SPEC = 'ANGLES' TKFRAME_-203221_UNITS = 'DEGREES' TKFRAME_-203221_ANGLES = (-0.085943669, -0.071619724, 0.0) TKFRAME_-203221_AXES = ( 1, 2, 3 ) FRAME_DAWN_VIR_IR_ZERO = -203223 FRAME_-203223_NAME = 'DAWN_VIR_IR_ZERO' FRAME_-203223_CLASS = 4 FRAME_-203223_CLASS_ID = -203223 FRAME_-203223_CENTER = -203 TKFRAME_-203223_RELATIVE = 'DAWN_VIR' TKFRAME_-203223_SPEC = 'ANGLES' TKFRAME_-203223_UNITS = 'DEGREES' TKFRAME_-203223_ANGLES = (-0.042971835, -0.085943669, 0.0) TKFRAME_-203223_AXES = ( 1, 2, 3 ) \begintext GRAND frames ======================================================================== This section of the file contains the definitions of the GRAND frames.
