What was Gladys west achievements?
Gladys West is a mathematician whose calculations and computer programming helped construct a geoid (a mathematical model of the earth’s shape). West’s modeling directly contributed to the ubiquitous use of the global positioning system (GPS) today.
When did GPS come out for civilians?
When GPS service was first made available for civilians in 1983, for national security reasons, the U.S. military decided to scramble the signal, making it a little too inaccurate to be reliable.
