Abstract
Global Navigation Satellite System (GNSS) accuracy improvement for GNSS-equipped mobile end user devices using error corrections calculated from the location information of other GNSS-equipped mobile end user devices. An algorithm in which GNSS signal data received by a network of GNSS-equipped mobile end user devices is collected and sent to a GNSS location correction engine, which calculates an ensemble error correction for the network and transmits the error correction to the GNSS-equipped mobile end user devices in the network. Implementations of the system and method may include selection of subsets of devices for inclusion in the calculations based on device location, time, hardware, and other factors.
