Two options that I know of: astropy.coordinates and sympy.mechanics.vector.
http://docs.astropy.org/en/v1.2.1/coordinates/index.html
- Defines many useful astronomical frames and the transformations between them
- Compatible with basic Python and NumPy types
- Does not support velocities https://github.com/astropy/astropy/issues/4344
http://docs.sympy.org/1.0/modules/physics/vector/index.html
- Supports kinematics
- Supports composition
- Simple implementation
- Closely tied to SymPy
