Most stars are still right there! My application of comet aphelion points to those areas is based on the scientific orbits provided by astronomy professionals to those locations. You really need to go read the 49 pages of the info I suggested. It goes into scientific detail how the GPS would work for star travellers with very fast ships.
The map would also need to be dynamic, adapting itself to the movements of astronomical objects, which are all moving around in all sorts of directions, all the time.
Consider that the orbit of the Earth is 186 million miles in diameter. It would be a shame to want to land on Earth, but miss it by 100 million miles, with a star and probably other objects in the way to getting there, and with which you might collide, too.
