This document was reviewed and approved for export, see Juno-Generic-15-001 This document has been reviewed and determined not to contain export-controlled technical data JUNO Reference Orientation CK File ============================================================= Created on Aug 08, 2022 by Martin Brennan, JPL. Summary ------------------------------------------------------------- This file contains an updated current reference attitude profile using the latest reference trajectory (spk_ref_211112_251021_211112.bsp). The CK starts before PJ38 and runs until just after PJ77. A +4.5/+0 deg Az/El attitude is implemented during the E45 Europa flyby encounter (pre-PJ45) to enable SRU and JunoCam sun-relative commanding, per MCR-80255. All remaining future perijoves are assumed to be a GRAV attitude. Note the planetary ephemeris (de440.bsp) and updated Jupiter system ephemeris (jup380s.bsp) are intended to be used with this CK. Start: 11 NOV 2021 23:58:51.000 UTC Stop : 20 OCT 2025 23:58:50.000 UTC The attitude mode for each perijove pass is listed below: PJ 00 JOI PJ 01 GRAV PJ 02 GRAV PJ 03 GRAV PJ 04 MWR PJ 05 MWR-tilt PJ 06 GRAV PJ 07 MWR PJ 08 GRAV PJ 09 MWR-tilt w/ 35deg-offset PJ 10 GRAV PJ 11 GRAV PJ 12 MWR -30/+20deg-offset PJ 13 GRAV PJ 14 GRAV PJ 15 GRAV PJ 16 MWR -30/+20deg-offset PJ 17 GRAV PJ 18 GRAV PJ 19 MWR-crosstrack: South-facing and offset 1.5deg East then 10deg North PJ 20 MWR -30/+5deg-offset PJ 21 GRAV PJ 22 GRAV PJ 23 GRAV PJ 24 59OFF & -4.5/+0deg-offset PJ 25 GRAV PJ 26 MWR +34/-9deg-offset PJ 27 GRAV PJ 28 GRAV PJ 29 GRAV PJ 30 GRAV PJ 31 GRAV PJ 32 GRAV PJ 33 GRAV PJ 34 GRAV PJ 35 GRAV & G35 -30/-4deg-offset PJ 36 GRAV PJ 37 GRAV PJ 38 MWR +29/-9deg-offset PJ 39 GRAV PJ 40 GRAV PJ 41 GRAV PJ 42 GRAV PJ 43 GRAV PJ 44 MAG 4off (+1/-4deg-offset) PJ 45 GRAV & E45 +4.5/+0deg-offset PJ 46 GRAV PJ 47 GRAV PJ 48 GRAV PJ 49 GRAV PJ 50 GRAV PJ 51 GRAV PJ 52 GRAV PJ 53 GRAV PJ 54 GRAV PJ 55 GRAV PJ 56 GRAV PJ 57 GRAV PJ 58 GRAV PJ 59 GRAV PJ 60 GRAV PJ 61 GRAV PJ 62 GRAV PJ 63 GRAV PJ 64 GRAV PJ 65 GRAV PJ 66 GRAV PJ 67 GRAV PJ 68 GRAV PJ 69 GRAV PJ 70 GRAV PJ 71 GRAV PJ 72 GRAV PJ 73 GRAV PJ 74 GRAV PJ 75 GRAV PJ 76 GRAV PJ 77 GRAV Implementation Notes ------------------------------------------------------------- The JUNO_SPACECRAFT orientation is provided in this file using a combination of two kinds of segments: - segments providing the orientation of the JUNO spin axis (+Z) encapsulated in the orientation of the JUNO_SPIN_AXIS frame (frame ID -61900) relative to the J2000 inertial frame. These segments were generated using SPICE utility program "prediCkt" based on the spin axis pointing profile from the source e-mail. See Appendix 1 below for more details about these segments ("prediCkt" inputs, fit accuracy, etc.) - segments providing the rotation of the spacecraft about the spin axis encapsulated in the orientation of the JUNO_SPACECRAFT frame (frame ID -61000) relative to the JUNO_SPIN_AXIS frame. These segments were generated using SPICE utility program "msopck" based on the rotation profile from the source e-mail. See Appendix 2 below for details about these segments ("msopck" setup parameters, input, etc.). The segments generated by "prediCkt" and "msopck" were merged together into a single file (this file) using SPICE utility "dafcat". After merging the file was augmented with these comments. Modeling Notes ------------------------------------------------------------- Users of this CK file should be aware that: - the time-lines in the source spreadsheet did not include Earth-repointing precessions - the spin axis pointing (+Z of the JUNO_SPIN_AXIS frame) was modeled to be within 0.25 degrees of JUNO-Earth, or JUNO-Anti Orbital Momentum Vector (depending of the attitude mode). The ZX plane of the JUNO_SPIN_AXIS frame was modeled to always contain Ecliptic North, with the +X axis to be as close to it as possible.

Resulting RA/Dec (deg) in J2000 (EME2000): 115.79257033 / 18.70042253 PJ38_MWRP29N9 orientation has +Z along +28.65338361 deg azimuth (towards Jupiter dusk) / -8.72687213 deg elevation (towards Jupiter S. Pole) offset from the Jupiter-Sun vector for PJ38, effectively toward Juno PON, where the off-Sun angel is less than 30 deg (29.996 deg). The equivalent J2000 vector is [-0.98539299 -0.006304016 -0.17017906]. Resulting RA/Dec (deg) in J2000 (EME2000): -179.63345732 / -9.79823023 PJ44_MAGP1N4 orientation has +Z along +1.0 deg azimuth (towards Jupiter dusk) / -4.0 deg elevation (towards Jupiter S. Pole) offset from Jupiter-Sun vector, where the off-Sun angle is 4.113 deg, the off-Earth angle is 8.395 deg, and the off-PON angle is 13.492 deg. The equivalent J2000 vector is [-0.99879910 0.01023930 -0.04791162]. Resulting RA/Dec (deg) in J2000 (EME2000): 179.41264643 / -2.74618470 PJ45_RMSUNOFFP5P0 orientation has +Z along +4.5 deg azimuth (towards Jupiter dawn) / +0.0 deg elevation offset from Jupiter-Sun vector, where the off-Sun angle is equal to 4.49727006513305 deg. The equivalent J2000 vector is [-0.98972914 -0.13776699 -0.03816404].
