GPS, traditionally, refers to the North American global positioning system, or satellite positioning system. This is how we can access locations. If there is any interference with the signal, it affects the location and information sent.
GNSS is a term that refers to the International Multi-Constellation Satellite System. This means that there is now access to more than just the GPS satellite, but other information that bases the data on more than just satellites.
