Abstract: Accuracy of Global Navigation Satellite System (GNSS) for GNSS devices is improved using a GNSS positioning system that leverages networked optimization for enhanced accuracy. GNSS measurements from multiple devices form the foundation for a massive pairwise optimization approach. This fuels a self-reinforcing cycle, wherein Real Time Kinematic (RTK) pairwise optimizations support Precise Point Positioning (PPP) analysis. Improved PPP calculations in turn refine RTK optimization, rapidly iterating towards convergence. The PPP-RTK feedback loop refines positions iteratively, culminating in more accurate user locations.

Abstract: A system and method for Global Navigation Satellite System (GNSS) accuracy improvement for GNSS devices using error corrections calculated from the location information of other GNSS devices. The system and method comprise use of an algorithm wherein GNSS signal data received by a network of GNSS 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 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.
