Certus Evo is an AI-based MEMS 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. Certus Evo is compatible with our post-processing kinematic (PPK) software Kinematica.
