MEMS gyroscopes have become indispensable in marine technology, especially in autonomous systems like Uncrewed Surface Vehicles (USVs) and Autonomous Underwater Vehicles (AUVs). By enabling accurate motion sensing and inertial navigation, these advanced gyroscopic devices play a crucial role in ensuring the precision and stability required for modern marine operations.
Micro-Electro-Mechanical Systems (MEMS) gyroscopes are compact sensors designed to measure angular velocity, a critical parameter for determining rotational motion. These devices leverage the gyroscopic effect to detect changes in orientation and movement, making them ideal for use in dynamic environments. MEMS technology combines mechanical and electronic components on a microscale, offering high performance and reliability for a wide range of applications.
When integrated into marine systems, MEMS gyroscopes excel at tracking angular speed and maintaining stability in harsh underwater and surface conditions. Their ability to deliver precise motion sensing ensures that Uncrewed Surface Vehicles (USVs) and Autonomous Underwater Vehicles (AUVs) can perform complex maneuvers with minimal error.
The operation of MEMS gyroscopes is based on the principle of Coriolis force. When a device rotates, tiny vibrating structures within the MEMS gyroscope detect shifts caused by rotational motion. These shifts are converted into electrical signals, which are then processed to determine angular velocity.
