CDPP 3DView Data Provider

CDPP 3DView provides planet, spacecraft, and comet trajectories in different coordinate systems. Its integration into Speasy makes it easy to get trajectory data for various missions on any time range.

Basics: Getting data from Cdpp3dView module

All the trajectories available are discoverable using speasy dynamic inventory, they are organized by mission/target/coordinate system:

>>> 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 ...>
