The Remmler Array was a space station in orbit of Arkaria and under the command of Starfleet. The station was controlled from the planetside Arkaria Base and was designed to conduct baryon sweeps on docked starships.
The Array consisted of two planar generators positioned parallel to one another. A starship would be parked with the generators to its port and starboard, and the sweep was conducted between the generators. Typically, it progressed from the stern to the bow of a starship. While the sweep was underway, all living biological material, including the crew, was evacuated to the planet. The Array was large enough to accommodate a Template:ShipClass starship, but the distance between the two generators could be adjusted to fit a smaller ship.
The sweep was deadly to living organic material and could also wreak havoc with certain ship systems. For that reason, Arkarian maintenance crews were usually dispatched to the ship to install field diverters in areas such as a ship's bridge, main engineering, and computer core.
The USS Enterprise-D stopped at the Remmler Array for its first baryon sweep in 2369. While there, several terrorists posing as maintenance crew attempted to steal trilithium resin from the ship's warp core, but were thwarted by Enterprise captain Jean-Luc Picard. (TNG: "Starship Mine")
