Claim Text:
1. A method performed by a powerline network server, the method comprising: receiving, from at least a first navigation satellite of a plurality of navigation satellites, a satellite navigation signal at the powerline network server of a powerline network, wherein the satellite navigation signal includes navigation data for a navigation device to determine position information associated with the navigation device; selecting a carrier frequency that is coherent with the satellite navigation signal and that does not interfere with a powerline signal frequency associated with a powerline signal; processing the satellite navigation signal, at the powerline network server, for transmission via a navigation carrier signal at the carrier frequency; and transmitting the navigation carrier signal and the powerline signal to the navigation device via the powerline network, wherein the powerline signal provides power to the navigation device, and wherein the powerline signal frequency provides a stable frequency reference that enables the navigation device to calculate an operational frequency of the plurality of navigation satellites using a pre-determined multiplier.
