GNSS Embedded INS
Field-proven Inertial Navigation Systems (INS-GNSS) engineered for mission-critical applications where precision, reliability, and real-time performance are essential. Our inertial navigation systems combine high-performance MEMS and Fibre Optic Gyro (FOG) technologies with intelligent sensor fusion algorithms to deliver accurate position, velocity, attitude, and heading information in GNSS-denied environments. Aeron's INS solutions are deployed across land, airborne, unmanned, robotics, and marine applications worldwide.
The INS systems offer GNSS-denied accuracies ranging from 0.1% of distance travelled or under 3 meters in a minute to 1% of distance travelled, depending on the variant. The performance of our INS systems is demonstrated repeatedly over hundreds of thousands of miles — choose from the smallest SWaP (Pollux 3) to one of the most qualified INS systems on the market (Octantis) for your application.
How Every Aeron INS Works
Octantis 2, Octantis 3, and Aldebaran all follow the same sensor-fusion approach — only the sensor grade and configuration change between them.
