A Brief History of GPS
In the 1970s the U. S. Department of Defense (DoD) conceived the idea of GPS out of a need to accurately determine the position of ballistic missile submarines prior to launching missiles. All the old methods of determining position had their flaws. Those methods were affected by atmospheric conditions, limited in range, subject to enemy jamming, or degraded by interference. See more on how GPS works.
GPS became common for commercial use in the mid 1980s for the surveying industry. For an in-depth history of GPS, click here.
