Abstract :
A possible correlation among GPS errors due to the effect of the ionospheric equatorial anomaly and HF measurements is investigated in this paper. HF measurements in a 1500 km long radio link, between Cuiaba (19.02S; 57.65W) and Rio de Janeiro (22.88; 43.28W), were carried out simultaneously with GPS signals measured in a station located near the middle point of this path in Presidente Prudente (22.12S; 51.37W). The preliminary analysis of the acquired data was shown to be promising enough. The result of this analysis could be the starting point for the development of a method for correcting errors observed in GPS stations set in equatorial areas.
