Navigational realtime relative timespace monitor sensor
The navigational realtime relative timespace monitor sensor was a navigational system. Aboard the  starships, there were at least two of these sensors.

In 2368, after the computer systems of the  were disrupted by a energy wave from a Satarran starship, Geordi La Forge accessed the basic system directories of the Engineering Department. According to the department, the navigational realtime relative timespace monitor sensors were off-line. ()
