Does Anise support CK kernels?

[saschakempf]

Many applications require knowledge about the current spacecraft attitude (the A in ANISE). Is there support for importing and using CK data?

Hi there,

CK kernels aren't currently supported because, as far as I know, they also require supporting spacecraft clock kernels, which aren't supported either. Once SCLKs are supported, CK kernels should be pretty quick because the interpolation code and DAF readers already exist.

However, ANISE currently supports instrument kernels that are in a different format than the SPICE ones. These allow one to define the rotation from a spacecraft orbital frame to an instrument, compute field of view (with both rectangular and conical FOV shapes), and compute the footprint of an instrument over time.

If you have an option to rebuild the attitude in ANISE, you can have a look at the tests from https://github.com/nyx-space/anise/blob/master/anise/src/structure/instrument/mod.rs#L329 and the documentation from https://nyxspace.com/anise/reference/instrument/.
