Locator beacon

From The Stargate Omnipedia


Technology designed to tag targets for Asgard transporter beams to gain a lock. Objects tagged by the beacon can differ, from a human to someting as massive as a Stargate. The small device can be easily concealed, and does not need to be activated remotely -- giving it a slight advantage over its larger predecessor, the emergency transponder. When always transmitting the coordinates the beacon gives off a minute energy anomaly, which can easily be fooled for other things.

For the safety and security of Earth's off-world personnel, the larger beacon device was quickly replaced by a subcutaneous implant.
