Abstract Zero value measurement is an important measurement of navigation receivers. The non-ideal characteristic of actual receiver channel, including the amplitude-frequency response and the phase-frequency response, has different influence on zero value estimate. Now, there is not a universal and quantificational analytic method for this problem. This thesis analyzes the impact of any non-ideal characteristic on zero value measurement quantificationally; then, verifies the analysis conclusion for a software receiver, the result agrees well with the analysis conclusion. The analytic model and method in this paper can be extended to analyze the impact of channel non-ideal characteristic on the zero value of carrier phase.
