| 11 | + - +Z axis is aligned with the north-pointing vector normal to the | |
| 12 | + mean equatorial plane of the Earth; | |
| 13 | + | |
| 14 | + - +X axis points along the ``mean equinox'', which is defined as the | |
| 15 | + intersection of the Earth's mean orbital plane with the Earth's mean | |
| 16 | + equatorial plane. It is aligned with the cross product of the | |
| 17 | + north-pointing vectors normal to the Earth's mean equator and mean | |
| 18 | + orbit plane of date; | |
| 19 | + | |
| 20 | + - +Y axis is the cross product of the Z and X axes and completes the | |
| 21 | + right-handed frame; | |
| 22 | + | |
| 23 | + - the origin of this frame is the Earth's center of mass. | |
| 24 | + | |
| 25 | + The mathematical model used to obtain the orientation of the Earth's mean | |
| 26 | + equator and equinox of date frame is the 1976 IAU precession model, built | |
| 27 | + into SPICE. | |
| 28 | + | |
| 29 | + The base frame for the 1976 IAU precession model is J2000. | |

| 313 | + Definition : | |
| 314 | + | |
| 315 | + Geomagnetic - geocentric. Z axis is parallel to the geomagnetic | |
| 316 | + dipole axis, positive north. X is in the plane defined by the Z axis | |
| 317 | + and the Earth's rotation axis. If N is a unit vector from the Earth's | |
| 318 | + center to the north geographic pole, the signs of the X and Y axes are | |
| 319 | + given by Y = N x Z, X = Y x Z.. See Russell, 1971 | |
| 320 | + | |
| 321 | + | |
| 322 | + The implementation of this frame is complicated in that the definition | |
| 323 | + of the IGRF dipole is a function of time and the IGRF model cannot be | |
| 324 | + directly incorporated into Spice. However, Spice does allow one to define | |
| 325 | + time dependent Euler angles. Meaning, you can define an Euler angle | |
| 326 | + that rotates GEO to MAG for a given ephemeris time t: | |
| 327 | + | |
| 328 | + V = r(t) * V | |
| 329 | + GEI MAG | |
| 330 | + | |
| 331 | + where r(t) is a time dependent Euler angle representation of a | |
| 332 | + rotation. Spice allows for the time dependence to be represented by a | |
| 333 | + polynomial expansion. This expansion can be fit using the IGRF model, | |
| 334 | + thus representing the IGRF dipole axis. | |
| 335 | + | |
| 336 | + IGRF-11 (the 11th version) was fit for the period of 1990-2020, which | |
| 337 | + should encompass the mission and will also make this kernel useful for | |
| 338 | + performing Magnetic dipole frame transformations for the 1990's and | |
| 339 | + the 2000's. However, IGRF-11 is not as accurate for this entire time | |
| 340 | + interval. The years between 1945-2005 are labeled definitive, although | |
| 341 | + only back to 1990 was used in the polynomial fit. 2005-2010 is | |
| 342 | + provisional, and may change with IGRF-12. 2010-2015 was only a | |
| 343 | + prediction. Beyond 2015, the predict is so far in the future as to not | |
| 344 | + be valid. So to make the polynomials behave nicely in this region (in | |
| 345 | + case someone does try to use this frame during that time), the | |
| 346 | + 2015 prediction was extended until 2020. So for low precision, this | |
| 347 | + kernel can be used for the years 2015-2020. Any times less than 1990 | |
| 348 | + and greater than 2020 were not used in the fit, and therefore may be | |
| 349 | + vastly incorrect as the polynomials may diverge outside of this region. | |
| 350 | + These coefficients will be refit when IGRF-12 is released. | |
| 351 | + | |
| 352 | + Also, since the rest of the magnetic dipole frames are defined from | |
| 353 | + this one, similar time ranges should be used for those frames. | |
| 354 | + | |
| 355 | + Definitive Provisional Predict Not Valid | |
| 356 | + |------------------------------|+++++++++++|###########|???????????| | |
| 357 | + 1990 2005 2010 2015 2020 | |
| 358 | + | |
| 359 | + In addition to the error inherit in the model itself, the polynomial | |
| 360 | + expansion cannot perfectly be fit the IGRF dipole. The maximum error | |
| 361 | + on the fit is .2 milliradians, or .01 degrees. | |
| 362 | + | |
| 363 | + The MAG frame is achieved by first rotating the GEO frame about Z by | |
| 364 | + the longitude degrees, and then rotating about the Y axis by the | |
| 365 | + amount of latitude. This matches the new frame to Russell's definition. | |

| 377 | + | |
| 378 | + Thus, this is much like GSM, except that now the +Z axis is the | |
| 379 | + primary, meaning it is parallel to the dipole vector, and +X is the | |
| 380 | + secondary. Since the X-Z plane is the same as GSM's X-Z plane, the Y | |
