Systems, methods, devices and subassemblies for creating and delivering crowd-sourced GNSS models

摘要

Systems, methods, devices and subassemblies for creating and delivering crowd-sourced GNSS models include receiving at one or more navigation receivers first signals transmitted by one or more navigation beacons, determining by the navigation receivers first navigation observables based on the received first signals, receiving at an augmentation server information associated with the first navigation observables, determining by the augmentation server augmentation information based on at least the received information associated with the first navigation observables and computational models, transmitting the augmentation information to the navigation receivers, receiving by the navigation receivers the augmentation information, receiving by the navigation receivers second signals transmitted by the one or more navigation beacon, determining by the navigation receivers second navigation observables based on the received second signals and determining by the navigation receivers a respective high-precision position, velocity, and time (PVT) solution based on the received augmentation information and the second navigation observables.

1. A method comprising:
determining first navigation observables by a navigation device from signals of one or more navigation beacons, the first navigation observables including information for determining a position, velocity and time (PVT) solution; submitting the first navigation observables from the navigation device to a navigation server; receiving crowd-sourced augmentation information by the navigation device from the navigation server in response, the augmentation information including corrections for perturbations in the first navigation observables that may reduce precision of the PVT solution, the crowd-sourced augmentation information being generated by the navigation server based on PVT solutions submitted by a plurality of navigation devices; and determining, by the navigation device, the PVT solution using second navigation observables and the augmentation information, including correcting the perturbations in the second navigation observables according to the augmentation information.
