Top 10 Companies in Hemispherical Resonator Gyroscope (HRG) Market: Outlook (2025

Market Overview

Hemispherical Resonator Gyroscopes (HRGs) are highly precise sensors that utilize the Coriolis effect to detect angular velocity. These sensors feature a hemispherical resonator that vibrates at specific frequencies; during rotation, Coriolis forces alter these vibrations, allowing measurement of rotational movement.

HRGs are known for their reliability, mechanical simplicity, and long operational life. They are widely applied in aerospace, defense, marine, and emerging autonomous systems. In 2023, global HRG market was valued at USD 148.59 million and is expected to reach USD 186.44 million by 2030, growing at a CAGR of 3.12% from 2024 to 2030.
