"I have a signal from Doctor Jackson's locator beacon."
Catherine Womack[src]

Locator beacons are devices designed to tag and lock targets for Asgard transporter beams. Targets can differ from a human to something as massive as a skyscraper. 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 are easily fooled as other signals.

Instances of use

  • The Trust used locator beacons to move the Stargate to their new Al'kesh, and themselves from the surface to their ship. SG-1 later used a Trust beacon to signal Prometheus to beam them and the Stargate aboard. (SG1: "Endgame")
  • Stargate Command tagged Daniel Jackson with a locator beacon before sending him back to Tegalus with Jared Kane, but the beacon was found separated from his body. After this event, Subcutaneous locator beacons were used. (SG1: "Ethon", "Off the Grid")
  • Locator beacons were placed on stolen Stargates by Lt. Colonel Samantha Carter so that the Odyssey could beam them aboard and then return them to their respective planets. (SG1: "Off the Grid")
  • Several captured Ba'al clones escaped the SGC using locator beacons in close proximity to each other; the signals became amplified, allowing the clones to break through the SGC jamming screen and beam to a tel'tak waiting in Earth orbit. (SG1: "Insiders")
  • The last Ba'al clone was eventually hunted down and captured using his locator beacon. Before the Tok'ra extracted him from his host, the clone revealed that the real Ba'al removed his beacon so that he couldn't be tracked and had a failsafe plan in place in case his clones were ever wiped out.
