Sensor maintenance was a room on Galaxy-class starships, were one would go to conducted routine maintenance on the sensor assemblies.

Galaxy Class ships were equipped with multiple sensors arrays, on both their primary and secondary hulls. Each of these arrays were made up of six sensor pallets, each one containing a variety of scanners. All of those were connected to the Sensor Maintenance room by a series of Optical Data Network (ODN) links.

From the room, officers could monitor the condition of any of the sensors and make any necessary adjustments. The Sensor assemblies require regular maintenance in order to ensure maximum efficiency.
