Technology designed to tag targets for Asgard transporter beams to gain a lock. Objects can differ from a human to a target as massive as a Stargate. The small device can be easily concealed, and does not need to be activated remotely. When always transmitting the coordinates the beacon gives off a minute energy anomaly, which can easily be fooled for other things. KEY EPISODE(S) - Endgame - The Trust use locator beacons to move the Stargate to their new Al'kesh, and themselves from the surface to their ship. Ethon - S.G.C. tags Dr. Jackson with a locator beacon before sending him back to Tegalus with Jarrod Kane, but the beacon is found and separated from his body.  |
