摘　　要：对于单频GPS接收用户,电离层时延是重要的测距误差.K lobuchar模型是一种计算方便、实用可靠、能够有效改正GPS单频接收机的电离层延时误差的方法.展示模型的演绎分析和具体解算方法,对GPS单频机解算程序编写有一定帮助.For single-frequency GPS receiver users, ionospheric delay is an important location error. Klobuchar model is U.S. scientists Klobuchar in 1987 by the application of single-frequency GPS receivers in the ionosphere delay correction methods. After years of observation verified, Klobuchar model is widely considered a more convenient terms, practical and reliable ionospheric delay the effective correction algorithms, and the model for the United States, China and Europe and other mid-latitude countries is particularly applicable. In this paper, Klobuehar model application of the practical value and model interpretations of reconciliation steps to be made a detailed analysis. Through the display of model analysis and interpretation of specific solution method, single-frequency GPS hope that the counting procedures for the preparation of a certain help.
