Marine Inertial Navigation Systems Market Report 2025

The marine inertial navigation systems market size has grown strongly in recent years. It will grow from $1.6 billion in 2024 to $1.73 billion in 2025 at a compound annual growth rate (CAGR) of 8.3%. The growth during the historic period can be credited to rising naval defense budgets, heightened demand for submarine navigation, the expansion of offshore oil and gas exploration, the growth of maritime trade routes, and the increasing use of autonomous underwater vehicles.

The marine inertial navigation systems market size is expected to see strong growth in the next few years. It will grow to $2.36 billion in 2029 at a compound annual growth rate (CAGR) of 8%. The expected growth in the forecast period can be attributed to increasing investments in marine automation, rising demand for accurate underwater navigation, expanded use of unmanned surface vehicles, growing applications in deep-sea research, and enhanced integration with satellite navigation systems. Key trends during this period include progress in micro-electro-mechanical systems technology, innovations in fiber optic gyroscopes, the development of compact navigation units, ongoing research in autonomous marine navigation, and the incorporation of artificial intelligence into inertial navigation systems.

The growing demand for offshore oil and gas exploration is expected to drive the expansion of the marine inertial navigation systems market in the coming years. Offshore oil and gas exploration involves searching for and extracting hydrocarbons beneath the ocean floor using specialized drilling and seismic technologies. This increasing demand is fueled by the need for energy resources that require advanced technologies to efficiently access untapped underwater reserves while maintaining safety and environmental standards. Marine inertial navigation systems play a crucial role in offshore oil and gas exploration by providing accurate vessel positioning and motion tracking in remote marine areas where satellite signals may be unreliable. For example, in December 2024, the Energy Information Administration (EIA), a U.S.-based government agency, reported that U.S. oil production rose from 12.2 million barrels per day in 2022 to 13.3 million barrels per day in 2023, while natural gas output increased from 121.1 to 128.8 billion cubic feet per day during the same period. Therefore, the rising demand for offshore oil and gas exploration is propelling the growth of the marine inertial navigation systems market.

Leading companies in the marine inertial navigation systems market are focusing on the development of advanced technologies such as GNSS-aided inertial navigation systems to improve precision and reliability in marine positioning and navigation. A GNSS-aided inertial navigation system combines global navigation satellite system (GNSS) signals with inertial sensors to deliver accurate and stable navigation information, even under challenging marine conditions. For instance, in March 2024, Kongsberg Discovery AS, a Norway-based technology firm specializing in ocean exploration, introduced Seapath 385, a cutting-edge marine inertial navigation system that integrates advanced sensors, multi-frequency satellite signals, and sophisticated algorithms for precise hydrographic surveying. This modular system provides reliable, high-frequency data and accurate vessel positioning in demanding marine environments.

In August 2022, EMCORE Corporation, a U.S.-based provider of advanced inertial navigation products, acquired the Fiber Optic Gyroscope (FOG) and Inertial Navigation Systems business segment of KVH Industries Inc. for an undisclosed amount. This acquisition allows EMCORE to enhance its standing in the inertial navigation market by incorporating advanced fiber optic gyroscope technology, expanding its manufacturing capabilities, and reaching new customers within the defense and industrial sectors. KVH Industries Inc. is a U.S.-based manufacturer specializing in high-performance sensors and integrated inertial systems for both defense and commercial applications.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sharp hike in U.S. tariffs and the associated trade disputes in spring 2025 are notably impacting the aerospace and defense sector by raising costs for titanium, carbon fiber composites, and avionics materials largely sourced from global suppliers. Defense contractors, locked into fixed-price government contracts, absorb these added costs, while commercial aerospace firms face airline pushback on higher aircraft prices. Delays in component shipments due to customs bottlenecks further disrupt tight production schedules for jets and satellites. The industry is responding by stockpiling critical materials, seeking waivers for defense-related imports, and collaborating with allied nations to diversify supply chain.

Marine inertial navigation systems are sophisticated onboard technologies that calculate a vessel’s position, speed, and orientation by detecting movement through internal sensors like accelerometers and gyroscopes. These systems are particularly crucial for underwater or remote maritime operations where GPS signals are unavailable, ensuring reliable and continuous navigation.

The primary types of marine inertial navigation systems include ring laser gyroscopes (RLG), fiber optic gyroscopes (FOG), micro-electro-mechanical systems (MEMS), quantum inertial navigation systems, and accelerometer-based systems. A ring laser gyroscope (RLG) uses laser beams traveling in opposite directions to sense rotation, offering high precision and dependable navigation. System variants include standalone, integrated, high-accuracy, and low-cost models. These systems find applications in aerospace, marine, land, submersibles, and missile guidance, serving end users such as shipbuilders, commercial shipping firms, defense agencies, research organizations, and offshore drilling companies.
