A GNSS receiver in general is an electronic device that receives and digitally processes the signals from a navigation satellite constellation in order to provide position velocity and time of the receiver. The result of the two programs is your current GPS coordinates which can be plotted on a map. A software GNSS receiver is a Global Navigation Satellite System GNSS receiver that has been designed and implemented using software-defined radio.
It includes a number of signal processing modules such as a High Performance ADS-B Decoder A Fast Sweeping SDR Spectrum Analyzer and a Radio Astronomy Utility for Hydrogen Line Spectroscopy.
The RTL-SDR is an ultra cheap software defined radio based on DVB-T TV tuners with RTL2832U chips. Software defined radio SDR is often described as a radio whose functionality is defined in software 1. On the software side he uses GNSS-SDRLIB and RTKLIB to decode the GPS signal. Unfortunately in the video Tech Minds was unable to get the Google Maps display to work but you can easily type the coordinates into Google maps yourself.
