There is nothing wrong with your television set. We control the vertical, we control the horizontal...

A scaled-down iteration of Space bridge technology, a GroundBridge allows transport to coordinates on a single planet, or even into the planet's orbit. Considerably easier to maintain and less costly in energon to operate, it is the primary means of coordinating Autobot forces on planet Earth. Most tellingly, GroundBridge technology requires no receiving terminal at the destination in order to function.

Fiction

Prime cartoon

When Cliffjumper called for backup, Autobot reinforcements converged on his location via GroundBridge.Darkness Rising, Part 1 When Cliffjumper's life signs were later detected by the computers in the Autobot base, the team likewise departed via GroundBridge to investigate. Ratchet was left behind to mind the Autobots' human guests, and explained to them that the team did not have the means to maintain a full space bridge, nor the energon to power such. As a result, they relied heavily on GroundBridge technology to dispatch the team to deal with alerts. Darkness Rising, Part 2

The GroundBridge control system was severely damaged during the Scraplet infestation, leaving Optimus Prime and Arcee marooned in the Arctic until the Autobots at base got it fixed. The Scraplets were sent through the bridge to the Arctic where they froze. Scrapheap The GroundBridge was still giving them trouble when Wheeljack arrived. This turned out to be just as well, since it was the Decepticon Makeshift posing as Wheeljack in an attempt to access the GroundBridge. Con Job

Moving the unstable D.N.G.S. by GroundBridge might have resulted in mass devastation, at least according to Optimus Prime. Using the GroundBridge on a moving target such as a train was also extremely dangerous, potentially causing mass displacement trauma, twisted limbs, or metal burn, however having the target's precise coordinates helped. Ratchet was forced to move the two older children onto a moving train to prevent MECH capturing the D.N.G.S. device. MECH terminated the Autobots' computer, forcing Prime to save the children as they could not be transported back. Convoy
