Contact Information ----------------------------------------------------------------------------- If you have any questions regarding this file contact the ESA SPICE Service (ESS) at ESAC: Alfredo Escalante Lopez (+34) 91-8131-429 spice@sciops.esa.int or the JUICE Science Operations Center at ESAC: Marc Costa Sitja (+34) 646-746-711 Marc.Costa@ext.esa.int Implementation Notes ----------------------------------------------------------------------------- This file is used by the SPICE system as follows: programs that make use of this frame kernel must "load" the kernel normally during program initialization. Loading the kernel associates the data items with their names in a data structure called the "kernel pool". The SPICELIB routine FURNSH loads a kernel into the pool as shown below: FORTRAN: (SPICELIB) CALL FURNSH ( frame_kernel_name ) C: (CSPICE) furnsh_c ( frame_kernel_name ); IDL: (ICY) cspice_furnsh, frame_kernel_name MATLAB: (MICE) cspice_furnsh ( 'frame_kernel_name' ) PYTHON: (SPICEYPY)* furnsh( frame_kernel_name ) In order for a program or routine to extract data from the pool, the SPICELIB routines GDPOOL, GIPOOL, and GCPOOL are used. See [2] for more details. This file was created and may be updated with a text editor or word processor. * SPICEYPY is a non-official, community developed Python wrapper for the NAIF SPICE toolkit. Its development is managed on Github.

The Nadir direction has been tuned to provide the best pointing budgets.

It is used as a sunshield during the cruise phase when close to the Sun. The JUICE High Gain Antenna, HGA, is rigidly attached to the -X side of the spacecraft bus. Therefore, the JUICE High Antenna frame, JUICE_HGA, is defined as a fixed offset frame with its orientation given relative to the JUICE_SPACECRAFT frame. The JUICE_HGA frame is defined as follows: - +Z axis is in the antenna boresight direction (nominally co-aligned to the spacecraft -X axis); - +Y axis is in the direction of the spacecraft +Y axis; - +X completes the right hand frame; - the origin of the frame is located at the geometric center of the HGA dish outer rim circle. X- and Ka-band antenna frames are defined such that their axes are nominally co-aligned with the axes of the JUICE_HGA frame and their origins are at the geometric centre of the HGA dish outer rim circle. These frames are introduced in order to include any possible misalignments between the X- and Ka-band pointing direction (maximum radiation power direction and gain).

At Jupiter, the MGA support the Radio Science Experiment (RSE) in parallel to observation by other instruments (in nadir pointing). It also supports emergency up- and downlink in safe mode. To provide a maximum coverage, the MGA is mounted on a steerable boom with two pointing mechanisms. The MGA Main Assembly (MGAMA) is accommodated at the -X/-Y/+Z corner of the spacecraft. Its Antenna Pointing Mechanism (APM) with two degrees of freedom provides a full spherical articulation range. To incorporate rotations in the antenna pointing mechanisms gimbals with respect to the medium gain antenna the MGA frame chain includes the following frames: JUICE_MGA_APM, JUICE_MGA_AZ, JUICE_MGA_EL_ZERO, JUICE_MGA_EL and JUICE_MGA.

The JUICE Medium Gain Antenna Azimuth frame -- JUICE_MGA_AZ -- is a Switch Frame (see Section ``JUICE Spacecraft Bus Frame'' and [1] for more information) aligned with one of the different CK-based base frames -- JUICE_MGA_AZ_MEAS or JUICE_MGA_AZ_PLAN -- depending on the available orientation data or coverage of these data. The orientation of these CK-based base frames are relative to the JUICE_MGA_APM frame and are rotated an Azimuth Angle about the JUICE_MGA_APM +Z axis. They are defined as follows: - +Y axis is rotated an Azimuth Angle from the JUICE_MGA_APM frame +Y axis around the JUICE_MGA_APM frame +Z axis; - +Z axis is parallel to the JUICE_MGA_APM frame +Z axis; - +X completes the right hand frame; - the origin of the frame is located at the APM yoke geometric center. The JUICE Medium Gain Antenna Elevation Zero frame -- JUICE_MGA_EL_ZERO -- is defined as a fixed-offset frame with respect to the JUICE_MGA_AZ frame as follows: - +Z axis is anti-parallel to the JUICE_MGA_AZ frame +Z axis; - +X axis is anti-parallel to the JUICE_MGA_AZ frame +X axis; - +Y completes the right hand frame; - the origin of the frame is located at the APM yoke geometric center. The JUICE Medium Gain Antenna Elevation frame -- JUICE_MGA_EL -- is a Switch Frame (see Section ``JUICE Spacecraft Bus Frame'' and [1] for more information) aligned with one of the different CK-based base frames -- JUICE_MGA_EL_MEAS or JUICE_MGA_EL_PLAN -- depending on the available orientation data or coverage of these data. The orientation of these CK-based base frames are relative to the JUICE_MGA_EL_ZERO frame and is rotated an Elevation Angle about the JUICE_MGA_EL_ZERO +Y axis. They are defined as follows: - +X axis is rotated an Elevation Angle from the JUICE_MGA_EL_ZERO frame +X axis around the JUICE_MGA_EL_ZERO frame +Yaxis; - +Y axis is parallel to the JUICE_MGA_EL_ZERO frame +Y axis; - +Z completes the right hand frame; - the origin of the frame is located at the APM yoke geometric center. The JUICE Medium Gain Antenna -- JUICE_MGA -- frame is defined a fixed offset frame relative to the JUICE_MGA_EL as follows: - +Y axis points from the gimbal toward the antenna dish symmetry axis; - +Z axis is in the antenna boresight direction; - +X axis completes the right hand frame; - the origin of the frame is located at the geometric center of the MGA dish outer rim circle. The MGA stowed position is at Azimuth = -180 deg and Elevation = 180 deg. After release, it is driven to a nominal position of Azimuth = 0 deg and Elevation = 0 deg. The rotations of the Azimuth and Elevation angles are stored in separated segments in CK files. In order to implement the misalignments from [21] the following calculations have been performed: - JUICE_MGA_APM is defined by the rotation matrix 'AZRF > SCRF' from [22], in addition a rotation of 90 degrees is applied around Y axis in order to nominally align the azimuth axis from [22] with the spacecraft Z axis. - JUICE_MGA_EL_ZERO is defined by the rotation matrix 'SCRF > ELRF (for AZ rot 180 degrees EL 180 degrees)' from [22] introducing the misalignment in the elevation axis. In addition two rotations of -90 degrees around X axis and 90 degrees around Z axis are performed to nominally coaling the elevation axis and the Y-axis of the azimuth frame for elevation equal to 0 degrees. The resulting matrix is multiplied by the rotation matrix to transform from JUICE_SPACECRAFT to JUICE_MGA_APM so to obtain the rotation matrix to transform from JUICE_MGA_EL_ZERO to JUICE_MGA_AZ (equivalent to JUICE_MGA_APM for azimuth equal to 0 degrees). - The correction of the positions of the APM Center and Phase Centers has been obtained by iterating the process of correcting first the APM Center applying the error calculated by comparing the average point of all the azimuth range with elevation equal to 0 for both SPICE data and [22] data. The position correction is then applied to the phase center by obtaining the average point for one elevation revolution for both SPICE data and [22] data.

The three main phases from the communication perspective are the Launch and Early Orbit Phase (LEOP), the commissioning and cruise phase, and the operational phase at Jupiter. During and after separation, full antenna coverage is necessary before a stable attitude is achieved, requiring two antennas with spherical coverage. In case of spacecraft survival mode, the LGAs provide the communication capability for recovery by ground operation. The optimum location of the LGAs providing maximum coverage is found on -X and +X side of the s/c, thus looking into HGA direction, respectively into the opposite direction of the HGA. The LGA installed in the +X panel of the JUICE Spacecraft frame -- JUICE_LGA+X -- is a ``fixed-offset'', defined with respect to the JUICE_SPACECRAFT frame as follows (from [15]): - +Z axis is in the antenna boresight direction (nominally co-aligned to the spacecraft +X axis); - +Y axis is in the direction of the spacecraft +X axis; - +X completes the right hand frame; - the origin of the frame is located at the geometric center of the LGA dish outer rim circle. The LGA installed in the -X panel of the JUICE Spacecraft frame -- JUICE_LGA-X -- is a ``fixed-offset'', defined with respect to the JUICE_SPACECRAFT frame as follows (from [15]): - +Z axis is in the antenna boresight direction (nominally co-aligned to the spacecraft +X axis); - +Y axis is in the direction of the spacecraft +X axis; - +X completes the right hand frame; - the origin of the frame is located at the geometric center of the LGA dish outer rim circle.

The Magnetometer Boom (MAG Boom) is one of the Instrument Supporting structures of the JUICE spacecraft. The MAG Boom is attached to the -X/-Z corner of the spacecraft main body and supports toward its outer end the J-MAG Inboard, Outboard and Scalar magnetometer sensors, and the Radio Wave Instrument and the Search Coil Magnetometer of the Radio and Plasma Wave Instrument (RPWI) experiments. The MAG Boom is a deployable structure comprising that ranges from 3.6m long in stowed configuration at launch (along +Zsc axis), up to 10.6m long in deployed configuration (in the -Xc, -Zsc quadrant).

This frame is describing the time dependent relationship between the Magnetometer Boom hinge and JUICE spacecraft fixed frames. Nominally the boom deploys from the boom hinge +X direction, making an angle of 141 deg from the spacecraft +Z axis after deployment. The Magnetometer Boom frame is defined as follows (from [24]): - +X axis is parallel to the boom and points from the boom deployment hinge toward its tip; and in stowed configuration is nominally co-aligned with the s/c +Z axis; - +Y axis is parallel to the Magnetometer boom's hinge rotation axis; - +Z axis completes the right hand frame; - the origin of the frame is located at the boom's hinge geometrical center.

The JUICE_NAVCAM-* are nominally co-aligned with the JUICE s/c frame. The instrument alignment has been measured after mechanical tests during the fourth alignment campaign as reported in [26]. The following misalignment is introduced as three rotations expressed in arcseconds from spacecraft to NAVCAM-* instrument reference frames: Rotation = ( 0.0, 757.0, 23.0 ) SC -> NAVCAM-1 Rz Ry Rx Rotation = ( 0.0, -605.0, 1691.0 ) SC -> NAVCAM-2 Rz Ry Rx 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_JUICE_NAVCAM-1 = -28051 FRAME_-28051_NAME = 'JUICE_NAVCAM-1' FRAME_-28051_CLASS = 4 FRAME_-28051_CLASS_ID = -28051 FRAME_-28051_CENTER = -28051 TKFRAME_-28051_RELATIVE = 'JUICE_SPACECRAFT' TKFRAME_-28051_SPEC = 'ANGLES' TKFRAME_-28051_UNITS = 'DEGREES' TKFRAME_-28051_AXES = ( 3, 2, 1 ) TKFRAME_-28051_ANGLES = ( 0.00002344, -0.2102778, -0.0063888 ) FRAME_JUICE_NAVCAM-2 = -28052 FRAME_-28052_NAME = 'JUICE_NAVCAM-2' FRAME_-28052_CLASS = 4 FRAME_-28052_CLASS_ID = -28052 FRAME_-28052_CENTER = -28052 TKFRAME_-28052_RELATIVE = 'JUICE_SPACECRAFT' TKFRAME_-28052_SPEC = 'ANGLES' TKFRAME_-28052_UNITS = 'DEGREES' TKFRAME_-28052_AXES = ( 3, 2, 1 ) TKFRAME_-28052_ANGLES = ( -0.00137778, 0.1680612, -0.4697202 ) \begintext JUICE Monitoring Cameras Frames -------------------------------------------------------------------------- Two JUICE Monitoring Units (JMU) and two JUICE Monitoring Cameras (JMC) are accommodated to enhance the observability of the spacecraft and its instruments, at marginal impact on spacecraft design and its budgets (power, mass). The small size of the camera (100 x 100 x 100 mm) helps to accommodate it on the optimum position, here also without impact on spacecraft design. The first camera is accommodated on the bottom of the +X wall, looking in +Z/+Y direction toward RIME +X antenna and +Y solar wing. The second camera is accommodated on the top of the +Z/+Y edge, looking towards -X/-Y allowing to monitor the first hinges of RIME -X antenna. Both cameras thus benefit from the +X spacecraft face favourable environment (no direct Sun illumination).

The GALA main unit base frame is defined by the laser altimeter design and its mounting on the spacecraft as follows: - +Z axis is along the nominal GALA laser head transmitter and receiver telescope boresights; it is nominally co-aligned with the spacecraft +Z axis; - +Y axis is co-aligned with the +Y spacecraft axis; - +X axis completes the right-handed frame; - the origin of the frame is located at the center of the GALA reference hole (RH) at the instrument's interface plane, i.e. the unit mounting plane to the spacecraft. Any misalignment between the nominal and actual GALA mounting alignment measured pre-launch should be incorporated into the definition of this frame. This diagram illustrates nominal JUICE_GALA_BASE frame with respect to the spacecraft frame. +Z s/c side view: ----------------- direction of flight ___________ HGA <--------------> \ / \ .__`._____.'__. \ / | | / \ | | \ / | +Zsc +Ysc / \=>o<===============>o-| o------->o<===============>o<=\ / -Y Solar Array |___. | | +Y Solar Array / \ | o------> | \ / ._|_|__|__+Ygala_base / \ | | \ | V +Xsc V +Xgala_base +Zsc and +Zgala_base are out of page Nominally, the GALA base frame is co-aligned with the s/c frame.

The innermost is called the in-board sensor (MAGIBS) and it is a fluxgate magnetometer. A second fluxgate magnetometer, called the out-board sensor (MAGOBS), is located approximately 3 meters away toward the end of the boom. A scalar magnetometer (MAGSCA) is located at the tip. The MAGIBS sensor frame -- JUICE_JMAG_MAGIBS -- is defined as follows (from [24]): - +X axis is parallel to the boom and points from the boom deployment hinge toward the sensor; - +Y axis is rotated 150 degrees around the +X axis from the boom +Y axis; - +Z axis completes the right hand frame; - the origin of the frame is located at the URF reference point hole -- located on one of the holes of the sensor baseplate. The MAGIBS sensor magnetic system science frame -- JUICE_JMAG_MAGOBS_SCI -- is defined as follows (from [28]): - +X axis is parallel to the boom and points from the boom deployment hinge toward the sensor (parallel to JUICE_JMAG_MAGIBS +X); - +Y axis is rotated 150 degrees around the +X axis from the boom +Y axis (parallel to JUICE_JMAG_MAGIBS +Y); - +Z axis completes the right hand frame; - the origin of the frame is located at the geometric center of the sensor. The MAGOBS sensor frame -- JUICE_JMAG_MAGOBS -- is defined as follows (from [24]): - +X axis is parallel to the boom's +Z axis; - +Y axis is parallel to the boom and points from the sensor toward the boom deployment hinge; - +Z axis completes the right hand frame; - the origin of the frame is located at the geometric center of the sensor. The MAGOBS sensor magnetic system science frame -- JUICE_JMAG_MAGOBS_SCI -- is defined as follows (from [28]): - +Z axis is parallel to the boom and points from the sensor toward the boom deployment hinge (parallel to JUICE_JMAG_MAGOBS +Y); - +X axis is parallel to the boom and points from the sensor toward the boom deployment hinge (parallel to JUICE_JMAG_MAGOBS +X); - +Z axis completes the right hand frame; - the origin of the frame is located at the geometric center of the sensor. The MAGSCA sensor frame -- JUICE_JMAG_MAGSCA -- is defined as follows (from [24]): - +X axis is the optical axis and is co-aligned with the spacecraft +Z axis; - +Y axis is co-aligned with the spacecraft +Y axis; - +Z axis completes the right hand frame; - the origin of the frame is located at the geometric center of the sensor. The MAGSCA sensor magnetic system science frame -- JUICE_JMAG_MAGSCA_SCI -- is defined as follows (from [28]): - +X axis is the optical axis and is co-aligned with the spacecraft +Z axis (parallel to JUICE_JMAG_MAGSCA +Z); - +Y axis is co-aligned with the spacecraft +Y axis (parallel to JUICE_JMAG_MAGSCA +Y); - +Z axis completes the right hand frame; - the origin of the frame is located at the geometric center of the sensor. The JUICE_JMAG_MAGSCA and JUICE_JMAG_MAGSCA_SCI frame definitions assume that the spacecraft Magnetometer Boom is nominally deployed with an angle of 141 deg. In order to account for deviations, the frame is defined as a Switch Frame (see [1] for more information) aligned with one of the different CK-based base frames -- JUICE_JMAG_MAGSCA_PLAN or JUICE_JMAG_MAGSCA_MEAS -- depending on coverage and their orientation is given relative to JUICE_MAG_BOOM.

This misalignment is constant therefore this frame is defined as a fixed offset frame relative to the JUICE_SPACECRAFT frame. - JUICE_MAJIS_SCAN is defined to capture orientation of the reflected instrument view direction due to the scan mirror motion. This frame is defined as a Switch Frame (see [1] for more information) aligned with one of the different CK-based base frames -- JUICE_MAJIS_SCAN_PLAN or JUICE_MAJIS_SCAN_MEAS -- depending on coverage. - JUICE_MAJIS_VISNIR and JUICE_MAJIS_IR are defined to capture misalignments for each of the two instrument channels relative to the reflected view direction. These frames are defined as fixed offset frames relative to the JUICE_MAJIS_SCAN frame. Each of the MAJIS frames listed above is defined in the same way as follows (from [7]): - +Z axis points along the boresight (for JUICE_MAJIS boresight is the nominal center pixel view direction for the scan mirror in "zero" position; for JUICE_MAJIS_SCAN boresight is the nominal center pixel view direction, "off-pointed" due to the scan mirror; for JUICE_MAJIS_VISNIR and JUICE_MAJIS_IR boresight is the particular detector center pixel view direction, "off-pointed" due to the scan mirror; adjusted for all known misalignments with the scan mirror in "zero" position) - +X axis is parallel to the apparent spatial resolution direction; it is nominally co-aligned with the s/c +X axis; - +Y axis completes the right hand frame; - the origin of the frame is located at the instrument focal point for JUICE_MAJIS_VISNIR and JUICE_MAJIS_IR frames and at the intersection of the nominal center pixel view direction and the scan mirror axis for JUICE_MAJIS and JUICE_MAJIS_SCAN frames.

This antenna is rigidly mounted on the science deck panel, perpendicular to the spacecraft YZ plane, and its radiation pattern is a toroid around the antenna's 4cm diameter cylindrical tube. In order to incorporate any misalignment between the antenna mounting and the spacecraft frame, the frames JUICE_RIME_BASE, JUICE_RIME+X and JUICE_RIME-X are defined: - +X axis is along the antenna's cylindrical tube, nominally co-aligned with the +X spacecraft axis; - +Z axis points along the +Z spacecraft axis, in the nominal nadir direction and corresponds to the maximum gain of the radiation pattern for all frequencies within the RIME bandwidth (see [9]) - +Y axis completes the right-handed system; - the origin of JUICE_RIME_BASE is the geometric centre of the RIME's antenna. - the origin of JUICE_RIME+X is the mounting point of the +X leg of the RIME's antenna. - the origin of JUICE_RIME-X is the mounting point of the -X leg of the RIME's antenna. This diagram illustrates nominal JUICE_RIME_BASE, JUICE_RIME+X and JUICE_RIME-X frames with respect to the spacecraft frame. +Z s/c side view: ----------------- .. || || || direction || of flight HGA __________|| <--------------> \ || \ .__`._____.'||. +Yrime-x \ / | ||o----> / \ | ||| \ / | +Zsc +Ysc +Yrime_base / \=>o<===============>o-| o---->o----->=============>o<=\ / -Y Solar Array | | ||| +Y Solar Array / \ | | ||o-----> \ / .______|____||| +Yrime+x / \ | |vv \ +Xsc V || +Xrime_base +Xrime+x || +Xrime-x || || RIME Antenna || || || .. +Zsc, +Zrime_base, +Zrime+x and +Zrime-x are out of page The JUICE_RIME_BASE, JUICE_RIME+X and JUICE_RIME-X frames are nominally co-aligned with spacecraft frame.

Therefore, for each of the JUICE targets, a RIME Nadir frame is defined taking this characteristic into account. In addition to these frames, which are target dependent, a generic RIME radiation pattern frame (JUICE_RIME) is provided. This later frame is a CK-based frame which takes into account, at different mission phases, the target being observed. The RIME Nadir frame(s) -- JUICE_RIME_NADC, JUICE_RIME_NADE, JUICE_RIME_NADG and JUICE_RIME_NADJ -- are defined as follows: - +X axis is along the antenna's cylindrical tube, nominally co-aligned with the +X spacecraft axis; - +Z axis is the component of the spacecraft to target vector which is perpendicular to the +X axis, with target either Callisto, Europa, Ganymede or Jupiter for JUICE_RIME_NADC, JUICE_RIME_NADE, JUICE_RIME_NADG and JUICE_RIME_NADJ respectively; - +Y axis completes the right-handed system; - the origin of this frame is the geometric centre of the RIME's antenna. All vectors are geometric: no corrections are used. The RIME radiation pattern (JUICE_RIME) frame is defined as follows: - For those missions phases where the spacecraft-target distance is less than maximum RIME operational requirement, the JUICE_RIME frame is co-aligned with the corresponding RIME Nadir frame for that given target. - For all other mission phases, the JUICE_RIME frame is co-aligned with the JUICE_RIME_BASE frame, i.e. nominally co-aligned with the JUICE_SPACECRAFT frame. Required Data: -------------- The RIME Nadir frames are defined as a two-vector frame using two different types of specifications for the primary and secondary vectors. The primary vector is defined as a constant vector in the JUICE_RIME_BASE frame, which provides the orientation for the RIME's antenna cylindrical tube, fixed with respect to the spacecraft frame. The secondary vector is defined as an 'observer-target position' vector and gives the Nadir looking direction to the target body, therefore, the ephemeris data required to compute the JUICE-target vector in J2000 frame have to be loaded before using this frame, with target being either Callisto, Europa, Ganymede or Jupiter, depending on the frame. The RIME radiation pattern frame is a CK-based frame, therefore loading of a CK that contains orientation data for the JUICE_RIME frame is required. This diagram illustrates nominal JUICE_RIME_BASE frame with respect to the spacecraft frame, as well as the different JUICE_RIME_NADx frames when no roll, pitch and yaw operations are applied to the spacecraft. +Z s/c side view: ----------------- .. || || || direction || of flight HGA __________|| <--------------> \ || \ .__`._____.'||. \ / | ||| / \ | ||| +Yrime_nad \ / | +Zsc +Ysc +Yrime_base / \=>o<===============>o-| o---->o----->=============>o<=\ / -Y Solar Array | | ||| +Y Solar Array / \ | | ||| \ / .______|____||. / \ | |v +Xrime_nad \ +Xsc V || +Xrime_base || || || RIME Antenna || || || .. +Zsc, +Zrime_base and +Zrime_nad are out of page This diagram illustrates the JUICE_RIME_NADx frames when the spacecraft +Z axis is only off-pointed along-track. -X s/c side (HGA side) view: ---------------------------- .

SWI is on the nadir platform in order to observe the target in nadir and limb viewing geometry. A clear field of view of +/-76 degrees along the track for 1) scanning across Jupiter, 2) viewing the Galilean satellites and 3) viewing cold space for calibration purpose is needed. Across the track SWI needs just a clear field of view of +/-4.3 degrees to scan across Jupiter in North- South direction.

Any misalignment between the nominal and actual SWI mounting alignment measured pre-launch should be incorporated into the definition of this frame.

The SWI Scanner frame, JUICE_SWI_SCANNER, is defined as a Switch Frame (see [1] for more information) aligned with one of the different CK-based base frames -- JUICE_SWI_SCANNER_PLAN or JUICE_SWI_SCANNER_MEAS -- depending on coverage and their orientation is given relative to JUICE_SWI_BASE as: - +Z axis is aligned to the SWI antenna boresight direction; i.e. direction of maximum gain of the receiver radiation pattern.

Therefore, the frame associated with it -- the UVS instrument base frame, JUICE_UVS -- is specified as a fixed offset frame relative with its orientation given relative to the JUICE_SPACECRAFT frame. The UVS instrument frame is defined by the spectrograph design and its mounting on the spacecraft as follows: - +Z axis is along the nominal UVS main entrance aperture boresight; it is nominally co-aligned with the spacecraft +Z axis; - +X axis is parallel to the apparent spatial resolution direction (i.e. along the slit); it is nominally co-aligned with the spacecraft +X axis; - +Y axis completes the right hand frame; it is nominally co-aligned with the s/c +Y axis; - the origin of the frame is located at the instrument focal point. Any misalignment between the nominal and actual UVS mounting alignment measured pre-launch should be incorporated into the definition of this frame.

Any misalignment between the UVS nominal boresight direction and the solar port boresight direction measured post instrument integration should be incorporated into the definition of this frame.

RADEM Frame Tree ~~~~~~~~~~~~~~~~ The diagram below shows the RADEM frame hierarchy: "JUICE_SPACECRAFT" ------------------ | |<-fixed | v "JUICE_RADEM" ------------- RADEM instrument frame ~~~~~~~~~~~~~~~~~~~~~~ The Radiation Monitor is rigidly mounted on the +X spacecraft panel. The boresights of ESD, PSD, HISD units and DD central opening are aligned with the spacecraft +X axis. Therefore, the frame associated with it -- the RADEM instrument base frame, JUICE_RADEM -- is specified as a fixed offset frame relative with its orientation given relative to the JUICE_SPACECRAFT frame. The RADEM instrument frame is defined by the radiation monitor design and its mounting on the spacecraft as follows: - +Z axis is along the nominal RADEM units main entrance apertures boresights; it is nominally co-aligned with the spacecraft +X axis; - +X axis is nominally co-aligned with the spacecraft -Z axis; - +Y axis completes the right hand frame; it is nominally co-aligned with the s/c +Y axis. Any misalignment between the nominal and actual RADEM mounting alignment measured pre-launch should be incorporated into the definition of this frame.

Therefore, the frame associated with it -- the HAA ADA frame, JUICE_HAA_ADA -- is specified as a fixed offset frame with orientation given relative to the JUICE_SPACECRAFT frame. The HAA ADA frame -- JUICE_HAA_ADA -- is defined as: - +Z axis is in the interface plane of JUICE with HAA and is nominally parallel to the s/c +Z axis; - +Y axis is normal to the JUICE-HAA interface plane and is nominally parallel to the s/c +Y axis; - +X axis completes the right-handed frame; - the origin is located in the centre of a reference hole on the interface plane between the ADA FEE and the satellite platform (i.e. the plane defined by the accelerometer mounting lugs aka datum plane).
