Review—Basic and Advanced Inertial Navigation Fluid-Based Technology

The article reviews most published inertial sensor technologies, including dynamically tuned, optical, MEMS vibratory, mechanical, solid-state, and fluid-based. working principles of the technologies are elaborated. Also, advantages disadvantages those sensors laid out. Owing to its excellent overall performance, such as simple structure, low cost, large measurement range, etc, current review focuses on state-of-the-art fluid-based technology accelerometers gyroscopes. sensing elements that used in accelerometer gyroscope explained. Moreover, a comparison analysis presented. shows thermal resistor has five orders magnitude which is highest dynamic range. However, porous transducer higher bandwidth almost 120 Hz. Furthermore, particle imaging velocimetry (PIVG) reviewed. PIVG an innovative measure angular rate where fluid proof mass. low-cost drift-free. Additionally, compared commercially available gyroscopes, provides superior signal-to-noise ratio (SNR).
