【 摘 要 】
This article presents experimental data on temporal changes in the level and phase of GPS signals as well as the results of their statistical processing. For the first time, correlations between the time correlation interval of the received radio signal level, flicker index and the time of its observation are reflected. For the first time, it has been shown experimentally that there is an inverse relationship between the correlation interval and the scintillation index. In addition, the frequency of changes in the signal level with oscillation frequencies on the order of hertz fractions is indicated. This information complements the results of the static processing of recommendations ITU-R P.531-13 and can be used to improve the efficiency of quasi-coherent processing of satellite signals.
