It will grow from $9.44 billion in 2025 to $10.02 billion in 2026 at a compound annual growth rate (CAGR) of 6.1%. The growth in the historic period can be attributed to increasing deployment of submarines and autonomous underwater vehicles, rising need for accurate navigation in gps-denied maritime environments, technological advancements in gyroscopes and accelerometers improving system precision, growth in naval modernization programs globally, expanding use of inertial measurement units in commercial and research marine vessels.

The marine inertial navigation systems market size is expected to see strong growth in the next few years. It will grow to $12.6 billion in 2030 at a compound annual growth rate (CAGR) of 5.9%. The growth in the forecast period can be attributed to growing adoption of hybrid navigation systems integrating inertial and satellite technologies, rising demand for high-accuracy navigation for autonomous and remotely operated maritime platforms, increasing investments in deep-sea exploration and offshore surveying, continuous enhancements in miniaturized and low-drift inertial sensors, expanding service requirements for calibration, software upgrades, and lifecycle maintenance. Major trends in the forecast period include advancements in high-precision gyroscope and imu technology, increasing adoption of compact and low-power marine ins for unmanned platforms, rising demand for hybrid navigation systems integrating ins with sonar and dvl, growth in aftermarket services including calibration, maintenance, and software upgrades, expansion of ruggedized marine ins for deep-sea and harsh-environment operations.

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.
