El repte/The challenge
Positioning performance in mass-market GNSS receivers embedded in mobile devices cannot be compared to that in professional GNSS receivers. Nowadays, one of the main limiting factors for that is the inability to access the raw GNSS data. This problem impedes to properly correct any predominant source of range error (specially ionosphere) affecting the user position.
This could be overcome by the use of more accurate corrections, such as from newer ionospheric GNSS models that are fed with big data and with more powerful computation strategies. In particular, the broadcast ionospheric model is too simple and typically corrects only the 50-70% of the ionospheric delay, with a remaining ionospheric error which can reach the level of few tens of meters, compromising seriously the objective of a positioning error at few meters level, specially for GNSS users at mid-low or low latitudes, and a further potential reduction up to the level of few decimeters at mid latitudes.
