Certus Evo is an AI-based GNSS-aided INS that provides extremely accurate position, velocity, acceleration, and orientation under the most demanding conditions. It offers FOG-like performance combined with the reliability and affordability of MEMS sensors. It features low SWaP-C (Size, Weight, Power, and Cost), internal data logging, and multiple communication interfaces for easy integration. Certus Evo is available in both OEM and rugged packages and comes standard with license-free 1 cm RTK position accuracy.

Ultra-High Accuracy MEMS

Certus Evo features some of the highest accuracy MEMS accelerometers and gyroscopes currently available. Certus Evo’s inertial performance exceeds some FOG IMUs and is up to 100x smaller and 10x cheaper. Certus Evo is put through Advanced Navigation’s intensive calibration process to provide consistently accurate data over an extended temperature range of -40°C to 85°C.

AI-Based Algorithm

Certus Evo features Advanced Navigation's revolutionary AI neural network sensor fusion algorithm. This provides accuracy of up to 10 times that of a traditional kalman filter. It was designed for control applications and has a high level of health monitoring and instability prevention to ensure stable and reliable data.

Dual Antenna RTK GNSS

Certus Evo contains a dual frequency RTK GNSS receiver that provides up to 1 cm accuracy positioning and supports all of the current and future satellite navigation systems, including GPS, GLONASS, GALILEO, BeiDou and QZSS. Dual antenna heading provides high accuracy heading that is not impacted by magnetic interference and has no motion requirements.

Time Synchronisation

Certus Evo contains a GNSS disciplined oscillator that can act as the primary time source within a distributed time system, enabling access to ultra-accurate system time using PTP or NTP network time sync. Certus also has a high-accuracy 1PPS and frequency output.

Multi Protocol Support

Certus Evo features multiple interfaces including Ethernet, CAN, RS232, RS422 and GPIOs. Certus supports all the industry standard protocols including NMEA 0183, NMEA 2000, TSS, PASHR, Simrad as well as a wide variety of proprietary protocols. It feaures a rich web UI and 256GB of internal logging.
