VSOP87 (and the subsequent VSOP2000 and VSOP2013) provide reasonably accurate planetary positions while still maintaining a small file size compared to the Chebyshev polynomial files.
VSOP includes our moon, but has anyone created something similar for other planets' moons (such as Jupiter's Io, Saturn's Titan, and Uranus' Ariel)?
I'm thinking about trying to create something like this and wanted to check that it hadn't already been done.
