Location Corrections Through Differential Networks System

In recent years, the development and use of internet enabled mobile devices with built in GPS receivers (e.g. cell phones, tablet computers) have seen substantial increases. Correspondingly, the quantity and variety of applications using the GPS capabilities of these devices have also increased. However, one limiting factor for some desired uses, such as establishing drop zones for package delivery, is that these devices typically have limited precise positioning capabilities due to minimizing Size, Weight, Power and Cost (SWaP-C) for their GPS antennas and chip sets. Research suggests that the expected positional accuracy for a typical mobile device (cell phone or tablet computer) is around 3-10 meters, which is prohibitive for applications that require higher precision.
