Paper Abstract

This paper presents a precise expression to describe the RMS code tracking error of navigation receivers, which is deduced under the following assumptions: the receiver code discriminator use coherent early-late algorithm or early-late power algorithm; the additive noise with arbitrary spectrum is gauss distributed and is independent of signal; the code tracking error is small enough to use the linear model. The theory is not restricted by bandwidth or ripple of receiver front end. The simplified expressions are also presented in case of white noise only. Comparison between theoretically predicted RMS code tracking error and simulation results are illustrated and validate the theoretical analysis result.
