Military satellite embarks on inaugural national security mission with the assistance of the Vulcan Centaur rocket (video)
The United Launch Alliance (ULA) has successfully launched its most powerful Vulcan Centaur rocket yet, marking a significant milestone in the development of next-generation navigation technology. The mission, which took place from Space Launch Complex 41 (SLC-41) at Cape Canaveral Space Force Station in Florida on August 12, sent the payload directly into geosynchronous orbit, a seven-hour journey that spans over 22,000 miles (35,000 kilometers).
The satellite, identified publicly only as Navigation Technology Satellite-3 (NTS-3), is a position, navigation, and timing (PNT) craft, similar to the GPS system. It features a phased array antenna that allows it to focus powerful beams to ground forces, combating jamming environments. This is a game-changing capability, according to Andrew Builta with L3Harris Technologies.
The satellite's advanced antenna allows it to direct energy precisely, enhancing the strength and resilience of GPS signals to mitigate interference from jamming attempts. This is part of next-generation navigation technology meant to operate effectively even in contested electromagnetic environments.
The experimental technologies tested on the Vulcan Centaur launch for navigation satellites primarily involve beam-focusing antennas to counter jamming. This forms part of the evolving suite of military GPS improvements targeting spoofing and jamming threats.
The first flight of Vulcan Centaur took place in January 2021, with Astrobotic's Peregrine lunar lander as the payload. However, the mission suffered an anomaly, and the lander fell back to Earth. An anomaly also occurred during the second flight of Vulcan Centaur, this time on the rocket's end, caused by a manufacturing defect on a nozzle of one of the solid side boosters. The U.S. Space Force certified Vulcan Centaur for national security launches following the successful overcoming of the anomaly during the second flight.
The Vulcan Centaur rocket launched with four side-mounted solid rocket boosters. It is worth noting that SpaceX is the other launch provider certified to launch military and spy satellites. Vulcan Centaur can launch from both Cape Canaveral and Vandenberg Space Force Base in California.
The launch of the NTS-3 satellite comes at a time when GPS jamming has become an increasingly worrisome problem for both the U.S. military and commercial satellite operators. The satellite marks the U.S. military's first experimental navigation satellite to be launched in 48 years.
The latest generation GPS satellites (GPS III and future GPS III Follow-On or IIIF) are already improving military GPS technology. They broadcast encrypted signals known as M-Code, designed to be both more powerful and harder to spoof. The IIIF generation will also feature regional military protection (RMP), focusing M-Code signals over smaller areas with much stronger intensity to resist jamming.
In summary, the experimental technologies tested on the Vulcan Centaur launch for navigation satellites primarily involved beam-focusing antennas to counter jamming and form part of the evolving suite of military GPS improvements targeting spoofing and jamming threats. The successful launch of the NTS-3 satellite marks a significant step forward in the development of next-generation navigation technology.
