When GPS fails

When GPS fails, it’s good to be able to use celestial navigation. A new product is available that will allow you to use it faster.
“After many years of effort, the PROFIX 2004 software program for absolute Celestial Navigation has passed its “shakedown trials” and will be relesed shortly. Finally, a Celestial Navigator will be able to establish the precise fix of his vessel anywhere in the World, from Celestial observations and ANY and ALL Celestial Bodies! The speed is phenomenal, and a precise fix can be completed within minutes – not hours – as all other celestial navigation systems presently require.”
