New Technology from the United States will make Russian "muffins" drones in Ukraine (video)

The suppression of satellite navigation underlies many radio electronic fighting systems that are actively used against drones in the war in Ukraine. To cope with this, ONENAV offers an unconventional solution: double the power of the latest GPS signal known as L5. This is a civil standard designed to work in the frequency range reserved for aviation services, in addition to available L1 and L2.

The L5 range is broadcast by part of the GPS constellation and other global navigation satellite systems such as European Galileo, Chinese Beidou and Japanese QzSS. ONENAV engineers have developed a L5 Direct receiver, originally intended for commercial use in smartphones and internet devices (IOT), but can be useful for drones.

According to the CEO of the company Steve Poyzer, the receiver directly accepts the signals of the L5 range without first fixing on the old signals of L1, which makes it resistant to the attempts of muffling. In April 2024, the equipment was successfully tested with high -electronic obstacles, in particular at the border of Ukraine and Poland, as well as in Israel, where the war is also underway. ONENAV specialists have compared the performance of L1 and L5 signals where GPS often does not work.

"While the researchers watched the large -scale muffling of L1 throughout the region, from Finland to Turkey, signals that directly received the L5 range were unacceptable to obstacle attempts," the company manager said. Steve Poiser added that the military can already use L5 receivers in drones, high -precision weapons, mobile radios and tracking systems for troops.

However, despite its high potential, the L5 signal has not yet become widespread because it is transmitted only 17 of the 31 GPS satellites in the Earth orbit. Full operation readiness with 24 L5 satellites is expected not earlier than 2027. The L5 signal is part of the GPS modernization plan, which will be implemented gradually as the constellation updates. Onenav recognizes that the L5 signal is not fully certified for critical applications and is still considered "pre -operational".

Most GPS receivers are not equipped for using L5 signals. Another problem was the introduction of the next generation of GPS operational management, known as OCX, which is lagging behind the schedule for several years, and without it it is impossible to use the capabilities of L5 to the maximum. Pentagon made several initiatives to reduce its addiction on GPS and vulnerability in the case of suppression of its signals.

For example, US space forces seek to use commercial innovations in PNT technologies (positioning, navigation and synchronization). "It is a smart government policy - to invest in a wide range of ways to get the exact time and location in real time. However, GPS/GNSS is the only global solution that uses the available infrastructure that is available today to civilians and the military today," Pyzner emphasized.

In a comment to Newsweek, the head of the company added that the use of L5-Direct receivers can significantly change the course of fighting in Ukraine, where GPS suppression affects everything from drones and missiles to critical infrastructure. "The transfer of critical technologies for war to use the latest GPS signal greatly contributes to the overcoming of Russian muffins," he assured.
