DefenceTalkGPS interferences have intensified in places as far away as Finland, the Mediterranean and Iraq since Russia invaded Ukraine, forcing aircraft to reroute or change destination, according to European aviation authorities. Disruptions to Global Navigation Satellite Systems (GNSS), which include GPS, are caused by the “jamming” or “spoofing” of satellite signals. Since the war erupted […]https://www.defencetalk.com/ukraine-war-disrupts-gps-in-finland-mediterranean-78448/

DefenceTalkAir Force Research Laboratory researchers Drs. Robert Bedford, Luke Bissell, Chandriker Dass and Michael Slocum are finding practical applications for the curious phenomena that occur in quantum materials. Until the late 1990s, the properties – or even the existence – of such materials seemed little more than theoretical. But, what is a quantum material? Once […]https://www.defencetalk.com/us-air-force-investigates-using-quantum-materials-in-new-navigation-tool-75437/

GPS III brings higher-power, more accurate and harder-to-jam signals to the GPS constellation The nation’s third next-generation GPS III satellite – and the first delivered by Lockheed Martin (NYSE:LMT) to the new U.S. Space Force — has arrived in Florida for an expected April launch. On Feb. 5, the third Lockheed Martin-built GPS III space […]

The 2nd Space Operations Squadron decommissioned Satellite Vehicle Number-36, the second to last Block IIA satellite, Jan. 27. Capt. Collin Dart, 2nd SOPS assistant flight commander of GPS mission engineering, said the disposal of SVN-36 will allow for newer vehicles to take it’s place. “The main reason it was decommissioned was because, at this time, […]

As well as providing global navigation services, Europe’s Galileo satellite constellation is contributing to saving more than 2000 lives annually by relaying SOS messages to first responders. And from now on the satellites will reply to these messages, assuring people in danger that help is on the way. This ESA-design ‘return link’ system, unique to […]

Lockheed Martin received a $25 million initial contract award for engineering and manufacturing development (EMD) for the GPS Spatial Temporal Anti-Jam Receiver (GSTAR) system that will be integrated into the F-35 as part of its modernization phase, also known as Block 4. The GSTAR system will replace the current Antenna Electronics Unit (AEU) and will […]
