To be able to measure all the figures of merits mentioned in the end of subsection 2. State of the art on signal analysis, we will implement our program on LabView. First, we will see how we can compute all the results we need. Then we will check if this implementation works correctly with simulated signals. Up to now, the program works without the USRP and no real satellite signals can be received. That is why the last subsection deals with the modifications brought to the Labview code to include the USRP acting as an RF front end to receive real satellite signals.
