CDPP 3DView Data Provider

CDPP 3DView (Centre de Données de la Physique des Plasmas 3DView) provides planet, spacecraft, and comet trajectories, each available in a choice of coordinate frames. Its integration into Speasy makes it easy to get trajectory data for various missions on any time range.

Note

This provider ships disabled by default (its web service has known issues that are still being addressed). Re-enable it by removing cdpp3dview from disabled_providers, see Disabling data providers.

Basics: Getting data from Cdpp3dView module

All the trajectories available are discoverable using speasy dynamic inventory, they are organized by body type then body name (e.g. Trajectories.SPACECRAFT.MEX); the coordinate frame is not part of the inventory tree, it’s a keyword argument to get_data() (see coordinate_frame below, default J2000):

>>> import speasy as spz
>>> trajectories = spz.inventories.tree.cdpp3dview.Trajectories
>>> trajectories
<SpeasyIndex: Trajectories>
>>> mex_traj = spz.get_data(spz.inventories.tree.cdpp3dview.Trajectories.SPACECRAFT.MEX, "2010-01-02", "2010-01-03")
>>> mex_traj
<speasy.products.variable.SpeasyVariable object at ...>
>>> mex_traj.shape
(144, 3)
>>> mex_traj.columns
['x', 'y', 'z']

>>> # Optional parameters: coordinate_frame and sampling (in seconds)
>>> mex_framed = spz.get_data(spz.inventories.tree.cdpp3dview.Trajectories.SPACECRAFT.MEX, "2010-01-02", "2010-01-03",
...                             coordinate_frame="ECLIPJ2000")
>>> mex_framed
<speasy.products.variable.SpeasyVariable object at ...>
>>> mex_sampled = spz.get_data(spz.inventories.tree.cdpp3dview.Trajectories.SPACECRAFT.MEX, "2010-01-02", "2010-01-03",
...                                sampling="60")
>>> mex_sampled
<speasy.products.variable.SpeasyVariable object at ...>

Coordinate frames

3DView supports far more frames than the other providers, and the list comes from the server rather than from Speasy, so this is always the authoritative check:

>>> frames = spz.cdpp3dview.get_frames()
>>> 'ECLIPJ2000' in frames
True

Passing a frame the server doesn’t know raises Cdpp3dViewWebException, and the message lists the frames that are available.

Note

coordinate_system (the kwarg name used by the SSCWeb and UiowaEphTool providers) is accepted as an alias for coordinate_frame here too, so switching between trajectory providers doesn’t require renaming a kwarg. Passing both with different values raises Cdpp3dViewWebException rather than silently picking one.

The table below is generated automatically from the server every time these docs are built, so it needs no manual updates and cannot go stale the way a hand-written list would. If the server couldn’t be reached during the build, a note below says so and a cached snapshot is shown instead:

The naming follows a consistent pattern across bodies, so you can usually guess an unfamiliar one:

IAU_<body> — body-fixed frame (rotates with the body), as defined by the IAU.
<X>SO — “X Solar Orbital”: a GSE-style, Sun-body-line frame generalized to body X.
<X>SM — “X Solar Magnetic”: like SM/GSM, referenced to body X’s magnetic dipole (only defined for the magnetized planets: Earth, Jupiter, Saturn).
<X>ECLIP / <X>EME — inertial frames centred on body X, referenced to the ecliptic or to Earth’s mean equator/equinox (the same convention as ECLIPJ2000/J2000) respectively.
<X>CSO — the comet/asteroid equivalent of the SO frames.
