Certus combines temperature calibrated accelerometers, gyroscopes, magnetometers, and a pressure sensor with a dual antenna GNSS receiver. These are coupled in an AI-based fusion algorithm to deliver accurate and reliable navigation data. It features low SWaP-C (Size, Weight, Power, and Cost), internal data logging, and multiple communication interfaces for easy integration. Certus is available in both OEM and rugged packages and comes standard with license-free 1 cm RTK position accuracy. Certus Dual Antenna GNSS/INS is compatible with our post-processing kinematic (PPK) software Kinematica.

Features

AI Navigation Algorithm

Certus features Advanced Navigation’s revolutionary AI neural network sensor fusion algorithm. This provides an 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.

High-Performance MEMS

Certus contains high performance MEMS sensors that are put through Advanced Navigation's intensive 8 hour temperature calibration process. This provides the highest accuracy possible from this sensor class and outputs consistent accuracy over the full temperature range from -40°C to 85°C.

Dual Antenna RTK GNSS

Certus 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 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 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.
