A running fix is generally accepted, from piloting, as a fix where earlier LOP's are advanced to cross a later LOP. In celestial navigation this is also true up to a point. When several observations of different bodies are taken in a relatively short period of time (5 to 30 minutes), the resulting fix is regarded as a simultaneous fix rather than a running fix, even though the earlier LOP's are advanced to the final LOP time. Star fixes taken at morning or evening twilight are examples of these fixes.
