In yet another embodiment, the orbital satellite 152 or other satellites may provide other functions such as global positioning and providing the network sign with location information or estimations of location information of the network sign directly without needing to pass information to the network 101. The location information or estimation of location information is known in the art. The network sign may also utilize use geolocation methods, e.g., global position system (GPS) techniques to determine location as known in the art, measuring and analyzing signal strength, using the multiple base stations to determine location without needing to pass information to the network 101. In an embodiment, the global positioning functionality of the orbital satellite 152 may use a separate interface than the communication functionality of the orbital satellite 152 (e.g., the global position functionality uses a separate interface, hardware, software, or other components of the network device 113 than the communication functionality) and the like. In another embodiment, the orbital satellite with the global position functionality is a physically separate satellite from the orbital satellite with communication functionality
