Certus Mini combines temperature-calibrated accelerometers, gyroscopes, pressure sensor and magnetometers with an advanced single antenna GNSS receiver. These are coupled in an AI-based fusion algorithm to deliver accurate and reliable navigation data. The Certus Mini features low SWaP-C (Size, Weight, Power and Cost) and multiple communication interfaces for easy integration. It is available in both rugged and OEM packages and includes license-free L1/L5 multi-constellation GNSS.

Certus Mini D is also available with a dual antenna GNSS receiver.
