The Hyperspace Orbiting Scanner or HOS was a device used by the Imperial CompLink.
Initially proposed by Geothray Camber and further refined by a team under Dr. Lindu Sencker, the HOS was left in hyperspace near a planet, and recorded the hyperspace shadows left by particles of a computer. The shadows would then be matched to the shadows of known computer languages to recreate the data. By the time of the Galactic Civil War, it was seventy-eight percent effective.
The HOS was served by Tech 4 PDVs that entered hyperspace, tracking the scanner through triangulations of known locations, a process that took hours to complete. Transfer of data from the PDV to the HOS, or effecting repairs to the HOS, had to be conducted in realspace, which was a vulnerable time for both apparatus.
