The US Department of Defense developed the satellite-based Global Positioning System (GPS) between 1973 and 1994. Accurate signals are sent by orbiting satellites to any receiver on the Earth's surface that is in their line-of-sight. With information from 4 or more satellites, the location of the receiver can be precisely determined.
Roger L. Easton is the principal inventor and designer of the GPS.
The Global Positioning System (GPS) was invented by the United States Department of Defense and became fully operational in 1995. It was developed to provide accurate navigation and positioning capabilities for military and civilian use around the world.

There were no electronics of any kind in the mid 1800s. For that matter, GPS was not invented until the early 1970s.
GPS was not invented for forty years after WWII ended. GPS depends on satellites orbiting the earth. The satellites get there by rocket. The first satellite did not orbit the earth until 1957.
