Abstract EN

High-precision GNSS application requires the exact phase center calibration of antenna.

Various methods are published to determine the locations of the phase center.

In the outfield, when the phase errors that arose by multipath exceed the phase center variations (PCV) tolerance, the calibration values may be not useful.

The objective of this paper is thus to evaluate the phase errors that arose by multipath signals.

An improved model of antenna receiving signal is presented.

The model consists of three main components: (1) an antenna model created by combination of right hand circular polarization (RHCP) and left hand circular polarization (LHCP), (2) a multipath signals model including amplitude, phase, and polarization, and (3) a ground reflection model applying to circular polarization signals.

Based on the model, two kinds of novel up-to-down (U/D) ratios are presented.

The performance of the model is assessed against the impact of up-to-down ratio of antenna on phase errors.
