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 using the SPICELIB routine FURNSH. This file
was created and may be updated with a text editor or word processor.

This section defined dynamic frames of interest to MAVEN science
investigations.
MAVEN MSO Frame
The MAVEN_MSO frame is the Mars-Sun-Orbit reference frame. It is
defined in the same way that the GSE system is defined for Earth.
The X-axis points from the center of Mars to the center of the Sun.
The Y-axis points opposite to the direction of the orbital velocity
component orthogonal to X. The Z-axis completes the right-handed
system (Z = X x Y). The orientation of this frame is not dependent
on the position or velocity of the MAVEN spacecraft.

Spacecraft Bus Frame
-------------------------------------------------------------------------------
The spacecraft frame is defined by the s/c design as follows [from 5]:
- Z axis is perpendicular to the Launch Vehicle separation
plane. The positive z direction is from the separation plane
toward/through the High Gain Antenna.
- X axis is is in the Launch Vehicle separation plane extending
from the origin through the scribe line on the outside
diameter of the Launch Vehicle Ring (nominally toward the
Articulating Payload Platform).
- Y axis completes the right handed frame;
- the origin of the frame is in the Launch Vehicle separation
plane at the center point of the outside diameter of the
Launch Vehicle Ring.

SEP Frames
The SEP frames -- MAVEN_SEP1, ID -202120, and MAVEN_SEP2, ID

s/c frame.
The MAVEN_SEP1 frame, for the sensor mounted on the +X/+Y corner of
the s/c +Z deck, is defined a follows (see [6]):
- +X axis is along the nominal boresight of the FOVs pointing
in the HGA (forward) direction
- +Y axis is nominally along the s/c +X axis
- +Z axis completes the right-handed frame
- the origin of the frame is at the CG of the sensor assembly.
The MAVEN_SEP2 frame, for the sensor mounted on the +X/-Y corner of
the s/c +Z deck, is defined a follows (see [6]):
- +X axis is along the nominal boresight of the FOVs pointing
in the HGA (forward) direction
- +Y axis is nominally along the s/c -X axis
- +Z axis completes the right-handed frame
- the origin of the frame is at the CG of the sensor assembly.

SWEA Frames
The SWEA science frame -- MAVEN_SWEA, ID -202130 -- is defined as a
fixed offset frame with respect to the s/c frame. Nominally it is
rotated from the s/c frame by +140 degrees about Z as shown on this

The SWEA science frame is defined with respect to the instrument's
anode layout. SWEA has 16 anodes (numbered 0 to 15) each spanning
22.5 degrees in the X-Y plane. In flight software and in ground data
analysis software, the +X axis of the frame is at the boundary
between anodes 0 and 15. To put +X in that direction, the SWEA
science frame is rotated by +140 degrees about the Z axis with
respect to the SWEA instrument frame (omitted from this FK), which,
as defined in [6], is co-aligned with the spacecraft frame. Thus,
SWEA science frame is rotated from the spacecraft frame by +140 degrees
about the Z axis.
The angle in the definition below is -140 because the rotation in the
definition is from the SWEA science frame to the spacecraft frame.

SWIA Frames
The SWIA "base" frame -- MAVEN_SWIA_BASE, ID -202140 -- is defined
as a fixed offset frame with respect to and is nominally co-aligned
with the s/c frame (see [6]).
The SWIA frame -- MAVEN_SWIA, ID -202141 -- is defined as a fixed
offset frame with respect to and is rotated first by +90 degrees
about X, then by +90 degrees about Z from the SWIA "base" frame.
The purpose of this frame is to co-align the frame's +Z axis with
the instrument's symmetry axis and the frame's +X axis with the s/c +Z
axis, which nominally points in the direction of the Sun, to allow
using azimuthal coordinates to represent directions relative to the
instrument (see [7]).

The LPW frames -- MAVEN_LPW_PY, ID -202151, and MAVEN_LPW_MY, ID

The MAVEN_LPW_PY frame, for the antenna extended in the s/c +Y

extended in the s/c -Y ("MY") direction, are defined a follows (see

- +Y axis is normal to the antenna base mounting surface, pointing
from the mounting surface toward the "top" of the base assembly
- +X axis completes the right handed frame

APP and APP-mounted Instrument Frames
-------------------------------------------------------------------------------
This section defines frames for the Articulated Payload Platform
(APP) and instruments mounted on it -- IUVS, STATIC, and NGIMS.
APP Frames
Four frames are defined for APP:
- MAVEN_APP_BP, ID -202501, is the APP base-plate frame defined
as a fixed offset frame relative to and is nominally
co-aligned with the s/c frame. This frame is called ``BP''
in [5].
- MAVEN_APP_IG, ID -202503, is the APP inner gimbal frame
defined as a CK-based frame and rotated by the inner gimbal
angle about Y relative to the MAVEN_APP_BP frame. This frame
does not exist in [5].
- MAVEN_APP_OG, ID -202505, is the APP outer gimbal frame
defined as a CK-based frame and rotated by the outer gimbal
angle about X relative to the MAVEN_APP_IG frame. This frame
is called ``AR'' in [5].
- MAVEN_APP, ID -202507, is the APP platform frame defined as a
fixed offset frame relative to the MAVEN_APP_OG frame and
nominally rotated from it first by -90 degrees about X, then
by -90 degrees about Z, and finally by +155 degrees about Y.
This frame is called ``APP'' in [5] with its axes labeled as
I (=X), J (=Y), and K (=Z).
Nominally at the gimbal angle pair 0.0/-155.0 the axes of the
MAVEN_APP frame point as follows:
- MAVEN_APP +X (APP +I) along s/c +Z
- MAVEN_APP +Y (APP +J) along s/c +X
- MAVEN_APP +Z (APP +K) along s/c +Y
as seen on these diagrams (the MAVEN_APP_IG and MAVEN_APP_OG frames

IUVS Frames
The IUVS frames defined by this FK include:
- IUVS base frame:
MAVEN_IUVS_BASE, ID -202510
- frames needed to model instrument pointing based on the
articulating mirror position:
MAVEN_IUVS_SCAN, ID -202517, and
MAVEN_IUVS, ID -202518
- frames defined for convenience of specifying various FOVs
(to align frame's +Z with the FOV center vector):
FRAME_MAVEN_IUVS_LIMB, ID -202511, and
FRAME_MAVEN_IUVS_NADIR, ID -202513,
- bright object sensor frames (with frame's +Z in the direction
of the BOS FOV center vector) :
FRAME_MAVEN_IUVS_LIMB_BOS, ID -202512, and
FRAME_MAVEN_IUVS_NADIR_BOS, ID -202514
The MAVEN_IUVS_BASE frame is defined as a fixed offset frame
relative to and is nominally co-aligned with the MAVEN_APP frame.
The MAVEN_IUVS_SCAN frame is defined as a CK-based frame and is
rotated from the MAVEN_IUVS_BASE frame about the +X axis by the
angle needed to align the +Y axis the MAVEN_IUVS_SCAN frame with the
actual view direction of the instrument for a given scan mirror
position.
The MAVEN_IUVS frame is defined as a fixed offset frame relative to
the MAVEN_IUVS_SCAN frame and is rotated from it by -90 degrees
about X to align the +Z axis of the MAVEN_IUVS frame with the actual
view direction of the instrument (+Y of the MAVEN_IUVS_SCAN frame).
The FOV frames -- FRAME_MAVEN_IUVS_LIMB and FRAME_MAVEN_IUVS_NADIR
-- are defined as fixed offset frames relative the MAVEN_IUVS_BASE
frame with their +Z axis pointing through the center of the
corresponding FOVs and their X axis pointing in the direction of the
MAVEN_IUVS_BASE frame's X axis. The following rotations are needed
to co-align the MAVEN_IUVS_BASE frame with each of the FOV frames:
FRAME_MAVEN_IUVS_LIMB -167.75 about X
FRAME_MAVEN_IUVS_NADIR -90.00 about X
The BOS frames -- FRAME_MAVEN_IUVS_LIMB_BOS and
FRAME_MAVEN_IUVS_NADIR_BOS -- are defined as fixed offset frames
relative the MAVEN_IUVS_BASE frame with their +Z axis pointing
through the center of the corresponding FOVs and their X axis
pointing in the direction of the MAVEN_IUVS_BASE frame's X axis. The
following rotations are needed to co-align the MAVEN_IUVS_BASE frame

Solar Array (SA) and MAG Frames
-------------------------------------------------------------------------------
This section defines frames for solar arrays and instruments mounted on
the solar arrays -- MAG.
Solar Array Frames
The solar array (SA) inboard panel frames -- MAVEN_SA_PY_IB, ID
-202300, and MAVEN_SA_MY_IB, ID -202400, -- are defined as fixed
offset frames with respect to the s/c frame.
The SA outboard panel frames -- MAVEN_SA_PY_OB, ID -202305, and
MAVEN_SA_MY_OB, ID -202405, -- are defined as fixed offset frames
with respect to the corresponding inboard frames.
All SA frames are defined as follows:
- +Z axis is along the normal to the panel active cell side
- +Y axis is along the panel edge parallel to the s/c YZ plane,
pointing from the s/c toward the end of the array
- +X axis completes the right handed frame
- the origin of the frame is at the geometric center of the
panel.
This diagram illustrates the SA frames:

As seen on the diagram
- the MAVEN_SA_PY_IB frame is co-aligned with the s/c frame
- the MAVEN_SA_PY_OB frame is rotated by +20 degrees about X
relative to the MAVEN_SA_PY_IB frame
- the MAVEN_SA_MY_IB frame is rotated rotated by 180 degrees about Z
relative to the s/c frame
- the MAVEN_SA_MY_OB frame is rotated by +20 degrees about X
relative to the MAVEN_SA_MY_IB frame
The angles in the definitions are the opposites of the rotations
described above because the rotations in the definitions are from
the structure frames to the base frames.

MAG Frames
The MAG sensor frames -- MAVEN_MAG_PY, ID -202310, and MAVEN_MAG_PY,
ID -202410, -- are defined as fixed offset frames with respect to
the corresponding outboard SA panel frames as follows (see [6]):
- +Y axis is normal to the sensor mounting plate and points from
the plate toward the top of the sensor,
- +Z axis is normal to the sensor side opposite to the cable
connector
- +X axis completes the right handed frame
- the origin of the frame is at the geometric center of the
sensor.
