This version of the document supersedes all previous versions.
The NAIF IDS required reading lists all default ID-name mappings for the
SPICE/CSPICE toolkits and a description of functionality of the
corresponding software.
SPICE system kernel files and subroutines refer to ephemeris objects,
reference frames, and instruments by integer codes.
An ephemeris object is any object that may have ephemeris or trajectory data such as a planet, natural satellite, tracking station, spacecraft, barycenter (the center of mass of a group of bodies), asteroid, or comet. Each body in the solar system is associated with an integer code for use with SPICE. The names and codes for many of these objects are listed below.
Spacecraft ID codes are negative. These ID codes are usually derived from NASA control authority assignments. Instruments mounted on spacecraft also have ID codes. These are determined by multiplying the spacecraft ID by 1000 and subtracting the ordinal number of the instrument from the resulting product. Thus we can algorithmically recover the spacecraft code from an instrument code, and each instrument may have a unique code as long as there are 999 or fewer on a spacecraft.
Caution: the NASA spacecraft ID control authority at GSFC is forced into reusing some IDs. This can affect the SPICE system for planetary or other spacecraft for which ID-name mappings are registered. (Here "registered" means a spacecraft for which use of the SPICE system is an actuality, or was contemplated.) Three cases exist.
As the reader will see, ID codes now show the wear that results from an expanding system. As the SPICE system has expanded so has the number of objects that require identifying codes. Many of these objects do not fit neatly into the schemes originally envisioned as needing ID codes. As a result, the current system is a bit eclectic.
Software exists within the SPICE system that allows a user to easily map
between an integer code and the object name that code represents or
vice-versa.
bodc2n_c performs the integer code to name mapping; input a code, the routine returns the corresponding name:
bodc2n_c ( code, lenout, &name, &found );
Where lenout defines the maximum string length for name.
bodn2c_c performs the name to integer code mapping; input a name, the
routine returns the corresponding ID code:
bodn2c_c ( name, &code, &found );
boddef_c performs a run-time assignment of a name/code mapping for later
translation by bodc2n_c and bodn2c_c:
boddef_c ( name, code );
name defines the character string associated with integer code. When
using bodn2c_c, the name look-up is case insensitive, left justified,
and space compressed (multiple spaces between words reduced to one)
format. Space between words are significant.
These strings are equivalent:
'EARTH', ' Earth ', 'earth '
As well as:
'Solar System Barycenter', 'SOLAR System barycenter'
but
'SolarSystemBarycenter'
is not due to the lack of spaces between words.
The boolean found has value true if a mapping look-up succeeded, false
otherwise.
If necessary, a user may elect to load additional name-ID pairs for
access by SPICE software. These pairs may be new definitions, or they
may override the default mapping assignment.
Create new name-ID pairs With a text kernel such as
\begintext
Define an additional set of body, ID code mappings.
\begindata
NAIF_BODY_CODE += ( 22, 23, 24, 25 )
NAIF_BODY_NAME += ( 'LARRY', 'MOE', 'CURLEY', 'SHEMP' )
Load the kernel as usual with a furnsh_c call. The names defined in
NAIF_BODY_NAME map to the corresponding index of NAIF_BODY_CODE, i.e.
LARRY->22, MOE->23, etc, and the IDs in NAIF_BODY_CODE map to the
corresponding index of NAIF_BODY_NAME.
If an external ID kernel is used, be aware of several rules:
\begindata
NAIF_BODY_CODE += ( 170100, 170101 )
NAIF_BODY_NAME += ( 'Enterprise', 'Enterprise-A' )
appends the two pairings to the existent set of mappings.
CAUTION: Use of the assignment operator, ''='', instead of the append operator, ''+='', destroys any previous name-ID definitions for a kernel variable.
As of release N53, the SPICE Toolkit provides the user the functionality
to override or mask any name/ID mapping. Use a boddef_c call or define
NAIF_BODY_NAME, NAIF_BODY_CODE assignments from a text kernel to perform
a masking operations. Simplistically, the mask functionality provides
the user the option of mapping multiple names to the same code.
Name/ID assignments function within a precedence hierarchy, so a lower precedence operation cannot affect previous assignments created by an operation of higher precedence. Kernel pool definitions have the highest precedence, boddef_c definitions next, and finally the default definitions. The order of assignments is significant.
Highest precedence
(1) Kernel pool final assignment
(2) Kernel pool initial assignment
(3) A BODDEF/boddef_c call final assignment
(4) A BODDEF/boddef_c call initial assignment
(5) The default mappings final assignment
(6) The default mappings initial assignment
Lowest precedence
Example 1:
Assign the name 'x' (lower case) to ID 1000 with boddef_c:
boddef_c ( "x", 1000 );
A call to bodc2n_c with 1000 as the input ID:
bodc2n_c ( 1000, lenout, &name, &found );
returns the name 'x'. The bodn2c_c calls:
bodn2c_c ( "x", &code, &found );
bodn2c_c ( "X", &code, &found );
both return the ID as 1000. Note the case insensitivity of the name
input.
Now a demo of simple masking functionality. Assign a new name to ID 1000:
boddef_c ( "Y", 1000 );
so the bodn2c_c call
bodn2c_c ( "Y", &code, &found );
returns an ID of 1000. In a similar manner, the bodc2n_c call:
bodc2n_c ( 1000, lenout, &name, &found );
returns the name 'Y'. Still, the code assigned to 'x' persists within
CSPICE as the call:
bodn2c_c ( "x", &code, &found );
also returns ID 1000. If we reassign 'Y' to a different ID:
boddef_c ( "Y", 1001 );
then make a bodc2n_c call with 1000 as the input ID:
bodc2n_c ( 1000, lenout, &name, &found );
the routine returns the name 'x'. We assigned an ID to 'x', masked it
with another name, then demasked it by reassigning the masking name,
'Y'.
If a boddef_c assigns an existing name to an existing code, that assignment takes precedence.
Example 2:
bodn2c_c ( "THEBE", &code, &found );
returns a code value 514. Likewise
bodn2c_c ( 514, &name, &found );
returns a name of 'THEBE'. Yet the name '1979J2' also maps to code 514,
but with lower precedence.
The boddef_c call:
boddef_c ( "1979J2", 514 );
places the '1979J2' <-> 514 mapping at the top of the precedence
list, so:
bodn2c_c ( 514, &name, &found );
returns the name '1979J2'. Note, 'THEBE' still resolves to 514.
In those cases where a kernel pool assignment overrides a boddef_c, the boddef_c mapping 'reappears' when an unload_c (or clpool_c) call clears the kernel pool mappings.
Example 3:
Execute a boddef_c call:
boddef_c ( "vehicle2", -1010 );
A bodc2n_c call:
bodc2n_c ( -1010, lenout, &name, &found );
returns the name 'vehicle2' as expected. If you then load the name/ID
kernel body.ker:
\begindata
NAIF_BODY_NAME = ( 'vehicle1' )
NAIF_BODY_CODE = ( -1010 )
\begintext
with furnsh_c:
furnsh_c ( "body.ker" );
the bodc2n_c call:
bodc2n_c ( -1010, lenout, &name, &found );
returns 'vehicle1' since the kernel assignment take precedence over the
boddef_c assignment.
The name/ID map state:
-1010 -> vehicle1
vehicle1 -> -1010
vehicle2 -> -1010
Now, unload the body kernel:
unload_c ( "body.ker" );
and the boddef_c assignment resumes highest precedence.
bodc2n_c ( -1010, lenout, &name, &found );
The call returns 'vehicle2' for the name.
CAUTION: Please understand a clpool_c call deletes all kernel pool mapping assignment. No similar clear functionality exists to clear boddef_c. boddef_c assignments persist unless explicitly overridden.
In theory, a unique integer can be assigned to each body in the solar
system, including interplanetary spacecraft. SPICE uses integer codes
instead of names to refer to ephemeris bodies for three reasons.
The smallest positive codes are reserved for the Sun and planetary
barycenters:

For those planets without moons, Mercury and Venus, the barycenter
location coincides with the body center of mass. However do not infer
you may interchange use of the planet barycenter ID and the planet ID. A
barycenter has no radii, right ascension/declination of the pole axis,
etc. Use the planet ID when referring to a planet or any property of
that planet.
Planets have ID codes of the form P99, where P is 1, ..., 9 (the
planetary ID); a planet is always considered to be the 99th satellite of
its own barycenter, e.g. Jupiter is body number 599. Natural satellites
have ID codes of the form
PNN, where
P is 1, ..., 9
and NN is 01, ... 98
or
PXNNN, where
P is 1, ..., 9,
X is 0 or 5,
and NNN is 001, ... 999
Codes with X = 5 are provisional.
e.g. Ananke, the 12th satellite of Jupiter (JXII), is body number 512.
(Note the fragments of comet Shoemaker Levy 9 are exceptions to this
rule.)

If an Earth orbiting spacecraft lacks a DSN identification code, the
NAIF ID is derived from the tracking ID assigned to it by the US Space
Command via:
NAIF ID = -100000 - US Space Command code
For example US Space Command assigned the code 15427 to the NOAA 9
spacecraft. This code corresponds to the NAIF ID -115427.
In July, 1992 Comet Shoemaker Levy 9 passed close enough to the planet
Jupiter that it was torn apart by gravitational tidal forces. As a
result it became a satellite of Jupiter. However, in July 1994 the
remnants of Shoemaker Levy 9 collided with Jupiter. Consequently, the
fragments existed as satellites of Jupiter for only two years. These
fragments were given the NAIF ID's listed below. Unfortunately, there
have been two competing conventions selected for identifying the
fragments of the comet. In one convention the fragments have been
assigned numbers 1 through 21. In the second convention the fragments
have been assigned letters A through W (with I and O unused). To add to
the confusion, the ordering for the numbers is reversed from the letter
ordering. Fragment 21 corresponds to letter A; fragment 20 to letter B
and so on. Fragment A was the first of the fragments to collide with
Jupiter; fragment W was the last to collide with Jupiter.
The original fragments P and Q subdivided further creating the fragments P2 and Q1.

ID codes for periodic comets begin at 1000001 and continue in sequence
indefinitely. (The current numbering scheme assumes that no need for
more than one million comet ID codes.) The current list of periodic
comets and their ID codes are given below. As new periodic comets are
discovered, this list will be expanded. The ID codes for a new comet
will be formed by adding one to the last comet ID in the current SPICE
list. As you can see the first portion of the list is in alphabetical
order. However, this pattern breaks down at ID code 1000112. This
reflects the fact that new periodic comets were discovered after
identification of the first 111. If you don't find the comet you are
interested in the first 111 comets listed look at the last 28 to see if
you can find the comet of interest.
Finally, note that Comet Shoemaker Levy 9 is included in this list (ID code 1000130) though it is no longer a comet, periodic or otherwise. It was an identified periodic comet prior to its breakup, which accounts for its inclusion in this list.

ID codes for numbered asteroids listed in the JPL Asteroid and Comet
Catalog [166.0] are determined via the algorithm:
NAIF ID code = 2000000 + JPL Asteroid number
For example, asteroid Yeomans (2956) has NAIF ID number 2002956. The
complete list of asteroids is far too numerous (over 4000 identified
asteroids) to include in this document. However, we include the NAIF ID
codes for the most commonly requested asteroids:
NAIF ID NAME
________ ____________________
9511010 'GASPRA'
2431010 'IDA'
2431011 'DACTYL'
2000001 'CERES'
2000004 'VESTA'
2000216 'KLEOPATRA'
2000433 'EROS'
2000253 'MATHILDE'
2009969 '1992KD'
2009969 'BRAILLE'
2004015 'WILSON-HARRINGTON'
2025143 'ITOKAWA'
There are three exceptions to the rule---asteroids Gaspra, Ida and Ida's
satellite Dactyl, visited by the Galileo spacecraft. The ID codes for
these asteroids were determined using an older numbering convention now
abandoned by the SPICE system.
The orbit of Dactyl has not been completely determined at the time of this writing. However, in anticipation of this determination, Dactyl has been assigned the NAIF ID code 2431011.
Note that if more than 431010 asteroids are ever identified and cataloged there will arise a conflict between the new numbering system and the ID code for Ida. At that time NAIF (or its successor) will need to add another exception to the asteroid numbering system.
The SPICE system accommodates ephemerides for tracking stations and
landed spacecraft. Currently five earth tracking station sites are
supported: Goldstone, Canberra, Madrid, Usuda, and Parkes. Note that
these refer only to the general geographic location of the various
tracking sites. IDs for the individual antennas at a given site are
assigned when more than one antenna is present.
The following NAIF ID codes are assigned.

Please refer to the Frames Required Reading document, frames.req, for
detailed information on the implementation of reference frames in the
SPICE system.
The ID code used to identify the on-board clock of a spacecraft
(spacecraft clock or SCLK) in SPICE software is the same as the ID code
of the spacecraft. This convention assumes that only one clock is used
on-board a spacecraft to control all observations and spacecraft
functions. However, missions are envisioned in which instruments may
have clocks not tightly coupled to the primary spacecraft control clock.
When this situation occurs, the correspondence between clocks and
spacecraft will be broken and more than one clock ID code will be
associated with a mission. It is anticipated that the I-kernel will
contain the information needed to associate the appropriate clock with a
particular instrument.
With regards to a spacecraft, the term ``instrument'' means a science
instrument or vehicle structure to which the concept of orientation is
applicable.
NAIF, in cooperation with the science teams from each flight project, assigns ID codes to a vehicle instrument. The instruments are simply enumerated via some project convention to arrive at an ''instrument number.'' The NAIF ID code for an instrument derives from the instrument number via the function:
NAIF instrument code = (s/c code)*(1000) - instrument number
This allows for 1000 instrument assignments on board a spacecraft. An
application of the instrument ID concept applied to the Voyager 2
vehicle (ID -32):
