The Inertial Labs has developed Motion Reference Units (MRU) to meet requirements from marine and hydrographic applications. MRU is enhanced, high-performance strapdown Motion Sensor, that determines Pitch & Roll, Heave, Sway, Surge, Ac celerations, Angular rates, Heading, Velocity and Positions for any device on which it is mounted. The Inertial Labs Motion Reference Units utilizes solid state 3-axes each of precision accelerometers, magnetometers, gyroscopes and barometric sensors to provide accurate Heave, Sway, Surge, Pitch and Roll of the device under measure.
Integration of very low noise gyroscopes output provides high frequency, real-time measurement of the Vessel, Ships, Helidecs, ROV, Marine antennas, Cranes rotation about all three rotational axes.
Through a combination of proven sector expertise and a continued investment in technological innovation, Inertial Labs delivers the optimum balance of price and performance ratio solutions for its customers.
Our MRUs featuring developed few micro g Bias in-run stability Micro Electro Mechanical System (MEMS)-based accelerometers. New generation of Inertial Labs 1 deg/hr Bias in-run stability MEMS-based gyroscopes are an ideal solution for demanding marine applications, with their electronic nature negating the problems associated with expensive mechanical gyro solutions, as well as those based on fiber optic (FOG) technology.
Inertial Labs MEMS gyroscopes set the standard for the industry, with our high-end MRUs featuring gyros that enable sector-leading accuracy and reliability standards.
