MRU - Motion Reference Units

Product Name:MRU - Motion Reference Units
Product Description:Affordable price: less than $4K for Heave or Pitch & Roll sensor and less than $7K for full motion sensor (5cm Heave & 0.05 deg Pitch & Roll dynamic accuracy). Qualification report is in attachment. The Inertial Labs has developed high precision and affordable 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, Accelerations, Angular rates, Heading, Velocity and Positions for any device on which it is mounted. Our MRUs featuring developed few micro g Bias in-run stability Advanced Micro Electro Mechanical System (AMEMS) -based accelerometers. New generation of Inertial Labs 1 deg/hr Bias in-run stability Advanced 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 Advanced MEMS gyroscopes set the standard for the industry, with our high-end MRUs featuring gyros that enable sector-leading accuracy and reliability standards. Qualification test report, made by Norwegian Motion Laboratory - attached.
