Early navigational aid (9)

Ross

I believe the answer is:

astrolabe

(Other definitions for astrolabe that I've seen before include "Early astronomical instrument" , "Old navigation instrument" , "heavenly model" , "Navigation aid" , "Old instrument for astronomical measurements" .)

I've seen this clue in the Sydney Morning Herald.
