Certus & Certus Evo

Certus and Certus Evo are low-SWaP GNSS-aided INS and AHRS modules that use temperature-calibrated accelerometers, gyroscopes, magnetometers and a pressure sensor, combined with sophisticated AI-based sensor fusion, to deliver high-accuracy output data for navigation and positioning at sea. The versatile units provide a range of interface options including Ethernet, CAN, serial RS232/RS422 and GPIO.

Incorporating dual-antenna moving baseline RTK GNSS and supporting all current and future GNSS constellations, the modules are ideal for marine surveying, platform stabilization, and ship motion monitoring.
