Smoothing pseudo ranges with ionosphere-free combinations of phase ranges can be useful for long rang positioning, since this new smoothing process can significantly remove the effect of ionosphere delays in positioning applications.

If the low frequency noise components and the hardware biases in pseudo ranges are reduced, the positioning performance with the smoothed pseudo ranges may be promising. In future GNSS receivers, both the noises and the hardware biases in pseudo ranges will be significantly reduced. Then, the positioning based on the proposed algorithm will be very useful.
