Atlans 3 is a lightweight all-in-one positioning and orientation system for land and air applications. It combines a unique MEMS-FOG hybrid technology and a high-quality dual-antenna RTK GNSS receiver within the same housing. As a very compact device, Atlans 3 is a real game changer as it can provide outstanding heading and position performance in the most challenging GNSS-restricted environments despite its small size. It provides continuous, accurate, and real-time navigation data that can be improved with Delph INS post-processing software.
