===============
1. After building the code, you will find the ```gnss-sdr``` executable file at gnss-sdr/install. You can make it available everywhere else by ```sudo make install```.
1. After building the code, you will find the ```gnss-sdr``` executable file at gnss-sdr/install. You can make it available everywhere else by ```sudo make install```. Run the profilers ```volk_profile``` and ```volk_gnsssdr_profile``` for testing all available VOLK kernerls for each architecture supported by your processor. This only has to be done the first time.
2. In post-processing mode, you have to provide a captured GNSS signal file.
1. The signal file can be easily recorded using the GNU Radio file sink in ```gr_complex<float>``` mode.
2. You will need a GPS active antenna, a [USRP](http://www.ettus.com/product) and a suitable USRP daughter board to receive GPS L1 C/A signals. GNSS-SDR require to have at least 2 MHz of bandwidth in 1.57542 GHz. (remember to enable the DC bias with the daughter board jumper).
