To change the bandwidth, enter an even decimation factor (256 or lower down to 4) into the "Decim" field. Explain the results. It can be tricky to capture GNSS signals, or any low-power satellite signal for that matter, because GNSS uses low-power spread-spectrum signals that are covered by the RF noise floor. Of course, it helps to had a scope or spectrum analyzer to see the result. Unfortunately, it is not possible save the data for later analysis. Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits. (See "Software-Defined Radios Help Explore RF Spectrum," July 11, 2012). In this specific scenario, the spectrum monitoring, the goal is to estimate the transmission power and direction of transmission of a directive source as in Figure 15.
