What is the difference between GIS and GPS?
You can think of GPS as a tool for collecting location data. That would be "walked" for later use: your smartphone using the location to recommend a restaurant, a migratory animal registrar recording their journey, or tracking a vehicle displaying a new roundabout in your area that you will later see on Google Maps.
After collecting data using GPS or any other method, the spatial data is then likely to end up in a spatially resolved database where it can be managed, accessed and analyzed by the GIS: for example, by adding topology, connections and directions for a roundabout, or timing and animal migration distances.

GPS . A global positioning system is a network of satellites that orbits the earth, allowing a receiver device to determine its location, speed, direction, and time. The receiver (commonly referred to as "GPS") must be connected to at least 4 satellites in order to determine its location and therefore its speed, direction and time. GPS is a US system and it is the only fully implemented global navigation satellite system. There are other GNSSs such as Russian GLONASS , COMPASS , and Indian IRNSS . GPS devices are now widely used as well as being integrated into other devices such as cars, smartphones and cameras.
A Geographic Information System (GIS) is a database implementation for spatial data. If a database can have text, numbers, dates, and photographs, it can have maps. It is not only a location, but also a location request and analysis of that location in relation to other locations. This is exactly the same as querying and analyzing tabular data. The only difference is that if a picture is worth a thousand words, a map is worth a thousand photographs.
GIS is a mixture of science (geography), information systems and modern software technologies.
