CROWDSOURCING ATMOSPHERIC CORRECTION DATA

A system and method crowdsources atmospheric data from one or more rovers. The rovers calculate an estimated ionosphere delay value that indicates an adverse effect of ionospheric activity on signals received from the GNSS satellite. The values and identifiers may be transmitted to a server. The server utilizes the received information to generate an ionosphere map that reflects the magnitude of ionospheric delay at different locations. The ionosphere map is transmitted to one or more rovers. The rover determines if a pierce point associated with a selected GNSS satellite in view of the rover falls within the boundaries of the ionosphere map. If so, a corresponding ionosphere delay value is obtained utilizing the ionosphere map and then applied as a correction to account for ionospheric activity. In addition, the central server and/or rover may transmit the estimated ionosphere delay values and identifiers to other rovers.
