By Inside GNSSThis follow-up to a 2007 Inside GNSS article looking at the potential future role for C-band in navigation details how, nearly 20 years later, it’s moved from an interesting idea to critical for resilient position, navigation and timing (PNT).
By Inside GNSSLocata’s radio based ranging and enhanced time synchronization algorithms are significantly enhancing timing stability—providing a resilient solution that complements GNSS and offers fiber-levels of performance without requiring the fiber.
By Inside GNSSBeginning in September, Controlled Reception Pattern Antennas (CRPA), a highly effective anti-jam technique, will no longer fall under stringent International Traffic in Arms Regulations (ITAR)—finally opening the market to U.S. manufacturers and expanding use of the technology.
By Renee KnightThe U.S. Space Force transferred Satellite Control Authority of the Global Positioning System (GPS) III Space Vehicle 07, to the 2nd Navigation Warfare Squadron, Mission Delta 31, operating at Schriever Space Force Base, Colo., on Jan. 8, 2025.
By Inside GNSSThe Lunar GNSS Receiver Experiment (LuGRE) will demonstrate GNSS-based spacecraft navigation in transit to the Moon and on the lunar surface. This will open the door to operational use of existing Earth-based GNSS signals for real-time onboard positioning, navigation, and timing (PNT) around the Moon, increasing mission capability while reducing reliance on ground networks for PNT.
By Inside GNSSAfter delays due to weather, on 16 December, U.S. Space Force’s Space Systems Command and Space Operations Command executed an accelerated timeline to meet a specific warfighter need through a Rapid Response Trailblazer launch.
By Inside GNSSSet to launch in late 2024, the NTS-3 satellite system developed by L3Harris together with the Air Force Research Lab (AFRL) is the Department of Defense’s first experimental, integrated navigation satellite system in 50 years.
By Richard ThomasEurope’s Galileo navigation system has taken a significant leap forward with the completion of a major upgrade to its Galileo Ground Segment. As one of the most complex ground segments ever developed in Europe, the challenge lay in seamlessly upgrading a system that serves more than four billion users globally—without disrupting service.
By Inside GNSSGovernment agencies and private industry worldwide are advancing toward a sustained presence on the Moon. In response, NASA, ESA and JAXA are collaborating to develop LunaNet—a network of cooperating networks designed to provide robust and interoperable lunar communications and PNT services.
