Is my celestial coordinate system efficient?

I want to know whether or not my starship's cordinate system is efficient or not. Soon after my race flew into the stars, we realised we needed to be able to tell where we were. We need coordinate systems. This particular system has an angle and a distance to define positions in space. The angle is a quaternion rotation from the sun (to avoid gimbal lock with euler coordinates) and a distance in light years along that angle. The 'right' of the sun is Earth's position from the sun on January 1st. Is this a good way of defining a position in the context of our spiral arm of the galaxy? What problems will I face using this system?

EDIT:

The 'right' of the sun specifies a basis for the Quaternion rotation.

January 1st 12 am is a unified time across all of Earth

A lot of people seem to be getting confused here. Quaternion rotation specifies an angle in 3D space. It defines any 3 dimensional direction.
