Septentrio launches OSNMA
June 2022 by Marc Jacob
Septentrio launches OSNMA (Open Service Navigation Message Authentication) on their high-end PolaRx5 reference receiver series. OSNMA offers end-to-end authentication on Galileo’s civilian signals, protecting receivers from GNSS spoofing attacks. Spoofing is a malicious form of radio interference, where faulty positioning information is sent into the receiver. OSNMA adds another layer of security to the existing AIM+ anti-jamming* and anti-spoofing technology that Septentrio receivers are known for. Such high level of resilience is especially important for reference receivers in applications which require assured PNT as well as in stationary critical infrastructure, which is especially vulnerable to GPS spoofing.
OSNMA authentication mechanism is also available on the mosaic™ GNSS module family and on Septentrio’s latest OEM boards. PolaRx5 receivers with OSNMA technology will be showcased by Septentrio at the ION JNC conference in San Diego, United States from 6-9 June, in booth 220. For more information about Septentrio receivers contact the Septentrio team.
* 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.
