LORD APPLICATION NOTE Inertial Sensing for Underwater ROVs and UUVs Precise Control, Stabilization, and Pointing with Best-in-Class Miniature Sensors The Challenge Underwater Remotely Operated Vehicles (ROVs) and Unmanned Underwater Vehicles (UUVs) operate in extremely demanding environments that require precise and reliable feedback. Inertial navigation solutions must be very accurate as well as small, lightweight, low power, and easy to integrate. The Solution LORD Sensing MicroStrain® inertial sensors provide high performance in a very small package. MEMS technologies, including very low-noise gyroscopes, combined with sophisticated Kalman filtering offer accurate data quantities to provide precise control, stabilization, and pointing at the best value.
Benefits Small, light, and easy-to-integrate on new and existing platforms Best-in-class industrial and tactical MEMS inertial systems Reduced development cost and rapid deployment Precise information for control, navigation, and geo-referencing is delivered via fusion of inertial data with information from DVL, GPS, depth, and sound velocity sensors Forward-compatible MIP™ communication protocol with flexible path to swap models with little or no rewriting of code Best performance vs. cost available
