Abstract
This article describes a method for measuring the delay of the modulation signal in the active antennas of the consumer’s navigation equipment. The influence of bandpass filter on the group time and the delay of the modulated signal was been analyzed. The model of the influence of anechoic chamber on the results of the delay measurements was been built. The delay measurement in an anechoic chamber was been made and the difference of signal delay in the active GNSS antenna using the modulated signals at the GDT was been shown.
