Various embodiments of the present invention provide systems, methods, and computer program products for providing improved augmentation for GPS calculations. In general, various embodiments of the invention involve using a plurality of GPS devices associated with stationary objects associated with a common carrier's delivery network and the common carrier's delivery fleet to calculate error corrections and to communicate these error corrections to a number of GPS enable devices to be used by these devices to augment GPS calculations to correct errors associated with GPS signals. Further, various embodiments of the invention involve collecting GPS data for a plurality of delivery routes traveled by the common carrier's delivery fleet. In particular embodiments, this collected data may be used to provide more accurate address information for locations along these delivery routes and more accurate renderings of various landscapes along these delivery routes.
