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.

Implementation of Frame Chains for Different Mission Phases ----------------------------------------------------------------------------- Different routes along the branches of the MMO frame hierarchy are implemented for different mission phases depending on the availability of the orientation data and the source, format and type of the data. This subsection summarizes mission phase specific implementations.

V "MMO_SPACECRAFT" ---------------- MMO Spacecraft and Spacecraft Structures Frames ----------------------------------------------------------------------------- This section of the file contains the definitions of the spacecraft and spacecraft structures frames. DISCLAIMER: The origin of the frames specified in the following definitions are not implemented. The ``true'' origin of all frames is in the center of the MMO_SPACECRAFT frame, the center of which is defined by the position given by the SPK (ephemeris) kernel in use. MMO Spacecraft Bus Frame ----------------------------------------------------------------------------- The MMO spacecraft frame -- MMO_SPACECRAFT -- is defined by the S/C design as follows (from [4]): - +Z axis is perpendicular to the MPO-MOSIF separation plane and points to the HGA in deployed configuration; - +X axis is parallel to the MPO-MOSIF separation plane and points to WPT-S1 antenna; - +Y axis completes the right-handed frame and is parallel to the MEFISTO antennas; - the origin of this frame is the Mercury Transfer Module/MPO interface point on the separation plane.

This frame is defined a fixed-offset frame.

In these files the MMO_SPACECRAFT frame orientation is not stored relative to the J2000 frame. Instead it is ``decomposed'' into two orientations: the nominal spin axis orientation captured in the segments providing the orientation of the MMO_SPIN_AXIS frame relative to the J2000 frame and the nominal rotation about the spin axis captured in the segments providing the orientation of the MMO_SPACECRAFT frame relative to the MMO_SPIN_AXIS frame. The MMO Spin Axis frame -- MMO_SPIN_AXIS -- is defined as follows: - +Z axis is nominally co-aligned with the IAU_MERCURY +Z axis; - +X axis is parallel to the MMO orbital velocity; - +Y axis completes the right-handed frame; - the origin of this frame is the Mercury Transfer Module/MPO interface point on the separation plane.

The outboard magnetometer is referred to as MGF-O, and its sensor is located at the tip of a 4.86 meters long extendable boom, which is dedicated to the fluxgate sensors. The inboard magnetometer is referred to as MGF-I and the sensor is mounted on the same boom with a distance of 1.56 meters from the boom tip. Extension of the boom will be performed in the initial phase of the MMO operation just after the separation of the MMO from the MCS (Mercury Composite Spacecraft) at the Mercury orbit. The MGF boom frame -- MMO_MGF_BOOM -- is defined as a fixed offset with respect to the MMO_SPACECRAFT frame as follows: - +Z axis is nominally co-aligned with the +Zsc axis; - +Y axis is nominally rotated 45 degrees around the +Zsc axis; and co-aligned with the boom such that this axis points from the inboard magnetometer sensor towards the outboard magnetometer. - +X axis completes the right hand frame; - the origin of this frame is located at the mast canister. The MGF frames -- MMO_MGF-I -- and -- MMO_MGF-O -- are defined as a fixed offset with respect to the MMO_MGF_BOOM frame as follows: - +Z axis is nominally co-aligned with the +Z boom axis; - +Y axis is nominally co-aligned with the boom such that this axis points from the inboard magnetometer sensor towards the outboard magnetometer. - +X axis completes the right hand frame; - the origin of these frames are located at the geometrical center of the each detector.
