GPS was originally developed for the U.S. military, but is now provided as a public service for people all over the world by the U.S. government.
Deployment of the GPS system began on 22 February 1978 with the launch of the first Block I Navstar GPS satellite. Initial Operating Capability was declared in December of 1993 with 24 operational GPS satellites in orbit. Full Operational Capability was declared in June of 1995.
GPS was developed by the U.S. military to help soldiers locate their positions. Civilian access to the GPS system was guaranteed by President Reagan as a response to the communist Chinese shooting down of Korean Airline Flight KAL-007. President Reagan hoped that GPS technology would help to prevent such a tragedy from happening again.
