- "I assume they have the new locator chip implants?"
- ―Paul Emerson[src]
Subcutaneous locator beacons, also known as subcutaneous transmitters or locator chips are beacons implanted under the skin of an individual, allowing them to be targeted by Asgard transporters, or tracked with handheld devices.
This also enables the wearer to be transported up to a ship usually via an Asgard beam and far quicker than usual. The devices first came into production in the aftermath of Dr. Daniel Jackson being captured on Tegalus which also saw him losing his Locator beacon.
As such, the new beacons were later introduced with SG-1, the main flagship team of Stargate Command being the first ever team associated with the Stargate Program to get the new implants before it was expanded presumably to all the other SG teams. (SG1: "Off the Grid", "Memento Mori")
The beacons are manufactured by Devlin Medical Technologies. (SGA: "Miller's Crossing")
Alternate timelines[]
- In an alternate timeline, Cameron Mitchell and Vala Mal Doran's locator beacons were still functioning in 1947 despite the two having been trapped since 1908, nearly forty years time which caused Mitchell to comment that the batteries on them must be very good. SG-1 decided to use the beacon to beam Mitchell out of Qetesh's Ha'tak after they two armed atomic bombs into Qetesh and Ra's ships. SG-1 used Mitchell's beacon to monitor him, but he suddenly ordered them not to beam him out. With time running out before Ra escaped, Mitchell's signal vanished from the Ha'tak as he escaped by ring transporter instead and An sent the bomb, killing Ra. Afterwards, SG-1 were able to use the beacon to find Mitchell in New York City and beam him aboard the Time Jumper. (SG1: "Roswell")
