SMC-02 Datasheet (255 KB)
SMC manufactures the SMC-02 range which is a small lightweight and compact available solution ready for a for seamless integration into third-party systems. The SMC-02 range is equipped with our SMC MRU firmware that has both standard and custom communication protocols, making it highly adaptable for use in a wide variety of applications within the Marine, Dynamic Positioning, Offshore, and Hydrographic industries.
Our compact SMC-02 Motion Reference Unit is designed to provide highly accurate motion measurement data and reliable performance in dynamic environments in all areas from small vessels to large rigs in all weather conditions.
The MRU is supplied with a windows-based Configuration Software. Connection using an Ethernet connection allows configuration from the built-in webserver using a standard Web browser. The supplied SMC Configuration software allows for easy configuration via Ethernet and Serial.

Each motion sensor is calibrated individually and the readings from the accelerometers and angular rate gyroscopes are adjusted for offsets, alignment, linearity and temperature variations, to ensure they meet the performance specifications.
We thoroughly test the SMC MRUs in our facilities during the calibration process with the use of a rate table with a controlled temperature chamber prior to delivery. The calibration is performed in a 2-axis rate table with a temperature-controlled chamber in a fully automated process.
