To mitigate ionospheric errors affecting positioning accuracy, an alternative approach involves operating directly in the position and clock domains. This method requires a Central Processing Facility (CPF) equipped with specialized software. Users would initially provide approximate device coordinates. Using this data, corrections would be computed for the device's vicinity across various potential positions, upcoming time epochs, and different sets of visible satellites. Results would then be relayed back to users to refine their positions. Initial tests indicate a notable 30-50% enhancement in accuracy, particularly in regions with significant ionospheric variations at low latitudes. This innovation could swiftly gain traction in areas lacking Satellite Based Augmentation Systems (SBAS). The advancement extends benefits to mainstream GPS and GLONASS chipsets, like those embedded in current smartphones, and is poised to encompass forthcoming GNSS chipsets that support multiple constellations (e.g., Beidou, Galileo) on a single frequency.
