𝐽∕𝑁 profile estimated for the second test conducted on the GPS/Galileo L1 frequencies. In the box: spectrograms of collected samples at the beginning of the test and after 500s. The zero frequency corresponds to 1575.42 MHz. After about 500 seconds from the start of the test, front-end saturation occurs, and the estimated 𝐽∕𝑁 starts flattening out.
