Lockheed Martin has announced that the first of the U.S. Air Force’s advanced new, higher-power, harder-to-jam GPS III satellites is making its way to the launch pad.

According to the company’s statement, on August 20, Lockheed Martin (NYSE: LMT) shipped the U.S. Air Force’s first GPS III space vehicle to Cape Canaveralfor its expected launch in December. Designed and built at Lockheed Martin’s GPS III Processing Facility near Denver, the satellite was shipped from Buckley Air Force Base, Colorado, to the Cape on a massive Air Force C-17 aircraft.

GPS III will be the most powerful and resilient GPS satellite ever put on orbit. Developed with an entirely new design for U.S. and allied forces, it will have three times greater accuracy and up to eight times improved anti-jamming capabilities over the previous GPS II satellite design block, which makes up today’s GPS constellation.

GPS III also will be the first GPS satellite to broadcast the new L1C civil signal. Shared by other international global navigation satellite systems, like Galileo, the L1C signal will improve future connectivity worldwide for commercial and civilian users.

“Once on orbit, the advanced technology of this first GPS III space vehicle will begin playing a major role in the Air Force’s plan to modernize the GPS satellite constellation,” said Johnathon Caldwell, Lockheed Martin’s program manager for Navigation Systems. “We are excited to start bringing GPS III’s new capabilities to the world and proud to continue to serve as a valued partner for the Air Force’s positioning, navigation and timing mission systems.”

GPS III SV01 is the first of ten new GPS III satellites under contract and in full production at Lockheed Martin.

In April, the company submitted a proposal to the government to build up to 22 additional GPS III Follow On (GPS IIIF) satellites which would bring even further enhanced capabilities to the GPS constellation’s more than four billion users.

Lockheed Martin’s GPS III satellites will have three times better accuracy and up to eight times improved anti-jamming capabilities. Spacecraft life will extend to 15 years, 25 percent longer than the newest GPS satellites on-orbit today. GPS III’s new L1C civil signal also will make it the first GPS satellite broadcasting a compatible signal with other international global navigation satellite systems, like Galileo, improving connectivity for civilian users.
