M2300
The M2300 is a MEMS-based inertial sensing system that is available as a GNSS-aided INS or as an MRU, providing three-dimensional data output that can be used for precision navigation and attitude control of small- and medium-sized crewed and uncrewed vessels as well as offshore equipment. High-performance processors and Extended Kalman Filters mitigate the effects of interference and inertial drift under highly dynamic conditions.
The compact and cost-effective unit is easy to install and is available in two different performance variants. Data can be output via serial RS-232/RS-422/RS-485 or via CAN.
