A stellar position relative to the navigational centerpomt.

The stellar positions too are of Hipparchan origin, despite Ptolemy's claim to the contrary.

He specialized in astrometry, making very precise measurements of stellar positions and motions.

Given its stellar position surrounded by other island peaks, no direct routes exist to Argus Mountain.

The precise measurement of stellar positions is part of the discipline of astrometry.

The star points were accompanied by still other markings which were the coördinates used for fixing a stellar position in hyperspace.

Over the centuries, this causes the apparent stellar positions to slowly change.

But in fact many of the stellar positions in his star catalogues were less accurate than that.

This suited her greater interest in basic observations such as determining stellar positions and providing calibrated magnitudes.

FAME would have measured stellar positions to less than 50 microarcseconds.
