The warp sensor grid was a type of sensor utilized by a Federation starship. A refit of these grids could be arranged by permission of Starfleet Command at a spacedock. In 2364, on stardate 41601.3, Captain Michael J. Lin of the USS Gremlin was informed by Admiral Gregory Quinn of Starfleet Operational Support Services that his request for a refit of warp sensor grids was denied due to budget considerations.
