Marker Satellite

Wraith Marker Satellites are an orbital that are left around worlds in the Pegasus galaxy which contain Human life. These satellites would remain dormant for centuries where they would remain in a hibernative state and collect energy through solar cells. Once they recieved a signal, they would power up and attempt to contact the rest of the Wraith, informing them that the world contained plentiful prey for culling.

These marker satellites were armed with weapons which open up like a flower blossoming and were capable of destroying a Puddle Jumper. They possessed some level of automation as evidenced by them capable of engaging in limited evasive manevuers.

The planet Halcyon had a marker satellite over it that remained dormant until activated by the Wraith known as Scar. The satellite was destroyed by Colonel John Sheppard who used his puddle jumpers Drone weapons to destroy it before it could notify the other Wraith Hives about the planet.
