December 2, 2019-CBS takes a look at the United States Air Force's military and civilian global positioning system (GPS) program, including how the Air Force protects against GPS jammers, and touches on the capabilities of Lockheed Martin's GPS III system that will be online soon. Two of the GPS III satellites are currently in orbit.
GPS III has three times better accuracy and up to eight times improved anti-jamming capabilities. Spacecraft life will extend to 15 years, 25 percent longer than any of the GPS satellites on-orbit today. GPS III's new L1C civil signal will also make it the first GPS satellite broadcasting a compatible signal with other international global navigation satellite systems, like Europe's Galileo, improving connectivity for civilian users.
