In this paper, the authors present a measurement of Signal-to Noise Ratio (SNR) for some global navigation systems, and making a comparison between such ratios. This ratio is an important measure to the quality of the signal as SNR increases the quality increases and vice versa. A new ratio is developed here, that is (Noise-to Signal Ration) NSR, it is found that as the value of NSR increases the quality decreases. The effects of both bit time and bit error rate on both SNR and NSR is studied. Both bit time and bit error rate effects on SNR, as such quantities increases SNR decreases.
