Abstract: The precision of the GPS navigation solution is affected by several types of error factors, in which the GPS signal delay by the ionosphere is the greatest after the omission of selective availability. This delay can be approximated by using one of the Ionospheric error correction models i.e. Klobuchar Algorithm, which estimate ionospheric time delay up to 50% or more, on a Root Mean Square (RMS) basis which is crutial to give the appropriate user position for single frequency GPS receivers. By using the Klobuchar algorithm, ionospheric range delay, the ionospheric time delay and Total Electron Content of ionosphere are estimated.In this paper the estimation of different ionospheric delay errors are presented after a systematic study of different parameters involved in this estimation.
