Septentrio showcases its latest anti-jamming and anti-spoofing GPS/GNSS tech at JNC



At ION JNC in San Diego Septentrio will demonstrate how simple it is to spoof or jam unprotected GPS receivers and how Septentrio’s resilient technology makes a difference for overall PNT security and availability.

Leuven, Belgium – May 31, 2022 -  Septentrio, a leader in high-precision GPS/GNSS* positioning solutions, will be showcasing at JNC (Joint Navigation Conference) how GPS jamming and spoofing** affect high-accuracy GPS receivers and the latest protection technology against such threats. A GPS spoofing demo will take a place as well as a detailed comparison of jamming solutions from various high-end receivers. The integration of the latest anti-spoofing authentication mechanism, called OSNMA will also be shown.

“With our growing dependence on GPS technology, resilience of PNT is an important point of attention especially for mission-critical applications, tactical ground or aerial vehicles as well as autonomous systems,” stated Gustavo Lopez, Market Access Manager from Septentrio. “Since the number of malicious jamming and spoofing attacks is on the rise, it is crucial to understand how various GPS receivers can be affected. We are pleased to explain and display this with specific examples at JNC this year.”

Advanced Interference Mitigation or AIM+, is an interconnected set of anti-jamming and anti-spoofing technology components comprising a robust defense system against various forms of GPS/GNSS interference. Such resilience to jamming combined with anti-spoofing measures ensures safety of autonomous machines, improves security of GNSS-based infrastructure and increases efficiency with extended PNT availability. OSNMA anti-spoofing authentication from Galileo is available on Septentrio receivers such as the mosaic module as well as the recently released AsteRx-U3 boxed receiver. Other products such as AsteRx-SBi3 also add inertial sensors for increase protection against spoofing. For more information about highly resilient PNT solutions and other Septentrio products please contact the Septentrio team. JNC conference takes place from 6 to 9 of June in San Diego, United States with Septentrio displaying their technology in booth 220.


* Global Navigation Satellite System including the American GPS, European Galileo, Russian GLONASS, Chinese BeiDou, Japan’s QZSS and India’s NavIC. These satellite constellations broadcast positioning information to receivers which use it to calculate their absolute position.

** Jamming is a form of radio interference which occurs when GPS frequency is overpowered by other radio waves. The result can be a loss of positioning accuracy or event total loss of position. Spoofing is a malicious form of radio interference, where misleading signals are sent into the receiver, resulting in faulty coordinates, which lead the target away from its predefined track.
