No, there was no GPS in 1918. Neither the concepts on which GPS operates had occurred to anyone nor was the primitive electronics of the time able to support its requirements had anyone thought of it. Also in 1918 it was not possible to put satellites in orbit.
The first satellite put in orbit was in 1957.
The concepts on which GPS operates were not worked out until the late 1960s.
The first launch of a GPS satellite was on February 1978; 39 years ago.
The GPS requires 24 operating satellites and 6 functional spare satellites in orbit to operate.
Early GPS receivers (available only to the military and large companies) cost tens of thousands of dollars and weighed from 20 to 100 pounds. This was all that was available until the very late 1980s.
One Hundred Years Ago was created on 1911-05-08.
