[Editor’s Note: This article was written and submitted by Mark Crews and John Betz.]

With the launch of the first next-generation GPS III satellite, GPS III Space Vehicle 01 (GPS III SV01), on December 23, 2018, the Global Positioning System (GPS) took a major step in modernizing technology and capability. The U.S. Air Force has continually improved GPS since the launch of the first GPS Block I satellite in 1978, and this ongoing modernization has provided new signals, greater accuracy, and increased robustness for civil and military users.
