A number of automated tracking cameras were installed as part of the Safeguard program, and one of these remains in use today to support overall operations of the Ronald Reagan Ballistic Missile Defense Test Site. The island also includes one of the two remote receivers for the TRADEX radar on Roi-Namur, the other remote is on Gellinam, close to Meck. When used together, the three radars are known as the Multistatic Measurement System, or MMS.
