precomputation

precomputation

[¦prē‚käm·pyə′tā·shən]
(navigation)
The process of making navigational solutions in advance, applied particularly to the determination of computed altitude and azimuth before making a celestial observation for a line of position; when this is done, the observation must be made at the time used for the computation, or a correction applied.
