Septentrio, a leader in high-precision GNSS positioning solutions, has launched Open Service Navigation Message Authentication (OSNMA) on its high-end PolaRx5 reference receiver series.

OSNMA offers end-to-end authentication on Galileo’s civilian signals, protecting receivers from GNSS spoofing attacks. OSNMA adds another layer of security to Septentrio’s existing AIM+ anti-jamming and anti-spoofing technology.

This high level of resilience is especially important for reference receivers in applications that require assured PNT as well as in stationary critical infrastructure, which is especially vulnerable to GPS spoofing.


The Septentrio PolaRx5 receiver with OSNMA technology will be showcased in booth 220 at the ION Joint Navigation Conference, taking place June 6-9 in San Diego.


“We are excited to offer OSNMA anti-spoofing technology now in our scientific and reference GNSS receivers,” said François Freulon, head of product management at Septentrio. “The addition of OSNMA to Septentrio’s already strong anti-jamming and anti-spoofing technology takes our receivers to a new level as resilient positioning and timing solutions for industrial applications and critical infrastructure.”

Septentrio has also updated the PolaRx5 product range with the latest RINEX format to support version 3.05 as well as version 4.0. With these updates, PolaRx5 becomes a leading scientific and reference receiver family supporting all of the new GNSS technologies introduced in 2022, Freulon said.

The OSNMA authentication mechanism is also available on the mosaic GNSS module family and on Septentrio’s latest OEM boards.
