Overview
Septentrio designs and manufactures multi-frequency GNSS receiver boards and modules that original equipment manufacturers integrate into their own systems. The company was incorporated in Leuven in January 2000 by Peter Grognard to commercialise satellite navigation know-how developed at the Interuniversity Micro Electronics Center (IMEC), where he had spent 18 months. Grognard led the company as CEO for 14 years and later moved to Thales Alenia Space. Products include the AsteRx1 Galileo-compatible receiver, multi-antenna GPS receivers for attitude determination and the AsteRx-m3 ProBase. The company received the Trends Gazelle award in 2007 and GPS World Products Leadership Awards in 2013 and 2018. Septentrio is headquartered in Leuven with offices in Espoo, Los Angeles, Shanghai, Yokohama and Seoul, and employs approximately 150 people. Revenue for 2024 exceeded EUR 50 million, with 20% year-over-year growth. Antoon De Proft is CEO. Septentrio operates within Hexagon's Autonomous Solutions division and keeps its own brand and operational independence.

- No tricks. Just reliable positioning. Halloween may be about surprises, but mission-critical operations are not. From autonomous systems and robotics to defence and industrial applications, reliable positioning matters when GNSS signals face interference, obstruction, or other challenges. Because confidence in your position shouldn't disappear when conditions become uncertain. #GNSS #Positioning #APNT #resilience #Autonomy
- This must be the greatest feature that Fugro AtomiChron® adds to the High Accuracy service! With the latest Septentrio mosaic-T FW 4.16.0 released this morning, you can now get real-time offsets to UTC(PTB), UTC(NIST), UTC(SG), UTC(JV) and UTC(IENG)! After careful calibration, this allows you to synchronize any integration that includes the mosaic-T to reach sub-ns level accuracy, real-time to these UTC(k) realizations! 🎉
- Work hard – play hard. By day, we solve positioning challenges. For Halloween, our Septentrio colleagues brought the spooky precision. 🎃👻 Check out the team’s Halloween faces! The vibes are right on target. 📡🕸️ #halloween #salesweek #oneteam #playhard

Join Septentrio and our panelists from Xona, European Space Agency - ESA and #Armada International for a discussion of the #JammerTest 2026 results and what real-world jamming and spoofing reveal about GNSS resilience. 📅 Tuesday, 8 December 2026 🕔 17:00 CET | 11:00 EST | 08:00 PST Register here: https://lnkd.in/ecrMa_HH #Septentrio #JammerTest2026 #GNSS #ResilientPNT
- GNSS talk? Put it on airplane mode. 📡✈️ Our Commercial team has been getting together in smaller groups for cosy dinners, good food and even better chats. No slides, no signal talk—just colleagues, connection and a little fine dining. 🍽️✨ Turns out, we have plenty to talk about beyond satellites. 😉 #TeamSeptentrio #cosydinner #GoodFoodGoodCompany
- AIM+ #Ultimate protects #mosaic-G5 P8 receiver from #spoofing at the Jammertest in Norway. https://ow.ly/aEal5101kVq A receiver without spoofing mitigation is spoofed into writing the word “Jammertest” across the Norwegian landscape. Competitor 1’s receiver shows positioning errors of hundreds of metres, while Competitor 2’s receiver shows errors of several tens of metres. The mosaic-G5 P8 module is not spoofed.
