Ionospheric biases correction for coordinates derived from GPS single point positioning

Most GPS users employ low cost receivers. These receivers do not allow users to record the pseudorange that
they observe, but the computed coordinates. This work presents an original and simple method to correct ionospheric
biases introduced in GPS signals. The originality of this method is based on the fact that no pseudorange
is needed to correct the biases, only the calculated coordinates are used. This distinguishes this method from other
classic alternatives. This paper evaluates the efficiency of the method with the use of real data.
