The earthdistance contrib module has a domain defined over the base type
cube (and contrib module) that can be used to store points on the surface
of a 3D sphere. The coordinates are stored in double precision, which should
be good enough for your requirements/

It shouldn't be too hard to have your application convert from DMS to
fractional degrees on input and output.
