You have unlocked the capability of creating a teleport beacon to Atlas Park.
How to Get
One obtains the Atlas Park Beacon supergroup badge by visiting all the Atlas Park exploration badge locations while in supergroup mode.
Note that visiting these locations while not in supergroup mode will not advance towards earning this beacon badge, even though it will earn the personal exploration badge for that marker.
The Atlas Park Beacon Badge location is (1809, 44, -2049), on the wall west of the Perez Park entrance.
