According to Fortune Business Insights™, the global ring laser gyroscope market size was valued at USD 4.92 billion in 2024 and is projected to grow from USD 5.29 billion in 2025 to USD 10.01 billion by 2032, exhibiting a CAGR of 9.5% during the forecast period. North America dominated the market with a 38.82% share in 2024, driven by robust aerospace and defense investments, technological innovation, and a high concentration of industry-leading players.
A Ring Laser Gyroscope (RLG) is a highly precise optical sensor used to measure angular rotation based on the Sagnac effect. It employs two counter-propagating laser beams within a closed-loop cavity. When the system rotates, a phase shift occurs, which is proportional to the rate of rotation. Unlike mechanical gyroscopes, RLGs have no moving parts, making them more durable, accurate, and resistant to drift. These features make RLGs ideal for inertial navigation systems (INS) in aircraft, spacecraft, missiles, submarines, and autonomous vehicles.

The ring laser gyroscope market is segmented into airborne, ground, maritime, and space platforms. The airborne segment held the largest share in 2024, driven by increasing aircraft production and global air traffic. RLGs are critical for ensuring flight control, stability, and accurate navigation, especially in GPS-denied environments. Rising defense investments and the growing use of Unmanned Aerial Vehicles (UAVs) further bolster demand for airborne RLG systems.
