How Galileo benefits high-precision RTK

August 9, 2017 - By , and

What to Expect with the Current Constellation This article demonstrates the benefits of Galileo integration for high-precision real-time kinematic (RTK) through representative case studies, considering baseline length, multipath impact and tree canopy. The results confirm usability of the current Galileo constellation in high-precision RTK applications and show improved availability, accuracy, reliability and time-to-fix in difficult measuring environments. Plus, Galileo-only RTK... read more

Harris delivers navigation payload for third GPS III satellite

August 9, 2017 - By

Harris Corporation has delivered the third of 10 advanced navigation payloads to Lockheed Martin, which will increase accuracy, signal power and jamming resistance for U.S. Air Force GPS III satellites. The advanced navigation payloads feature a Mission Data Unit (MDU) with a unique 70-percent digital design that links atomic clocks, radiation-hardened computers and powerful transmitters — enabling signals three times more... read more

Army pseudolites: What, why and how?

August 9, 2017 - By

In the battle for reliable positioning and timing, the U.S. Army is engaged in a multitude of activities, including mounted and dismounted A-PNT (assured position, navigation and timing) systems, anti-jam technology and pseudolites. The idea is simple: Take some GPS satellites, and put them on or near the ground. Now you have a navigation system where you have full control... read more

Expert Opinion: Spoofing attack reveals GPS vulnerability

August 8, 2017 - By

An apparent mass GPS spoofing attack in June involved more than 20 vessels in the Black Sea and suggests that Russia may be aggressively experimenting with signal disruption and spurious substitution. On June 22, a vessel reported to the U.S. Coast Guard Navigation Center: “GPS equipment unable to obtain GPS signal intermittently since nearing coast of Novorossiysk, Russia. Now displays... read more

Draper equips UAVs with vision for GPS-denied navigation

August 7, 2017 - By

A team from Draper and the Massachusetts Institute of Technology (MIT) has developed advanced vision-aided navigation techniques for UAVs that do not rely on external infrastructure, such as GPS, detailed maps of the environment or motion capture systems. When a firefighter, first responder or soldier operates a small, lightweight flight vehicle inside a building, in urban canyons, underground or under... read more
