| Summary: | The analytical relations determining the dependence between the accuracy of positioning objects-subscribers on the GNSS signals and the accuracy of pseudorange measurements were obtained. Based on these relationships, the relationship between positioning accuracy and the distribution of power radiated by the antennas into the space is revealed, which allows us to estimate the error of pointing the antenna beams in space. The correlations are based on the assumption of a Rayleigh channel for GNSS signal propagation. It is shown that the positioning accuracy of objects at the pseudo range error of 1 m and a beam width error of 2 degrees determines the average reduction in signal power in the radio channel, due to errors in positioning objects, not more than 0,25 dB, the normalized value of the standard deviation is equal to 13,5 dB. Due to positioning errors it is possible to reduce the signal strength in the radio channel by up to 1 dB. |
