A method is provided for receiving, at a processing system, and from a plurality of Global Navigation Satellite Systems (GNSS) stations, navigation data corresponding to computed positions of the plurality of GNSS stations. The method can further include determining, based at least in part on received navigation data and received GNSS transmitter information, ionosphere and atmosphere refractivity corresponding to intersections of two or more GNSS signals. The method can include calculating, based on the determined 3D density states, data fields of a model representing the three-3D density states. The method can include transmitting position adjustment data to calibrate a navigation position of at least one of the plurality of the GNSS stations based at least in part on the calculated data fields of the model."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for improved atmospheric monitoring and GPS positioning utilizing GNSS tomographic refractivity","description":"The disclosed technology relates to systems and methods for determining three-dimensional atmospheric and ionospheric density using refraction of electromagnetic waves.
