The HOS, short for Hyperspace Orbiting Scanner, was a tool utilized by the Imperial CompLink.
Originally conceived by Geothray Camber and subsequently improved by a group led by Dr. Lindu Sencker, the HOS was positioned in hyperspace close to a planet. It then captured the hyperspace shadows created by computer particle emissions. These shadows were compared against known computer language shadows to reconstruct the information. By the era of the Galactic Civil War, its success rate was seventy-eight percent.
Tech 4 PDVs serviced the HOS. These PDVs ventured into hyperspace and monitored the scanner's position using triangulations of established coordinates, a procedure that required several hours. The transfer of information from the PDV to the HOS, or the performance of repairs on the HOS, necessitated operation in realspace, posing a period of susceptibility for both the scanner and the PDV.
