Abstract
GPS receivers obtain GPS navigation data from acquired GPS satellites and determine a position of the GPS receiver. However, the GPS receivers may not always be in view of the GPS satellites or may receive GPS signals that are too weak to decode. Moreover, assisted GPS techniques rely on the ability of the GPS receivers to connect to auxiliary channels to receive navigation data, which might not always be possible. Functionality for powerline-aided GPS can be implemented to provide the navigation data, with varying levels of accuracy via a powerline network, when the GPS satellites are not in view of the GPS receiver. Moreover, the GPS receiver can use the navigation data to determine the position of the GPS receiver and/or to synchronize a local clock in the GPS receiver. Receiving the navigation data can ensure that the GPS receiver has a fast time to first fix.
