Sensor grid

A sensor grid was a large collection of sensors.

In 2371, the upper sensor grid of Deep Space 9 failed. Chief Miles O'Brien told Benjamin Sisko he would have it operational again by the morning of the next day. 

The Dominion had installed a sensor grid in the Soukara system by 2374. In that year, Worf and Jadzia Dax found that there were three gaps in the grid, all located in an asteroid field.
