Global Inertial Navigation System Market Expands with Growing GPS-Denied Applications

According to the latest market research study published by P&S Intelligence, the global inertial navigation system market was valued at USD 12.1 billion in 2024 and is projected to reach USD 17.5 billion by 2032, expanding at a CAGR of 4.9% from 2025 to 2032. This steady growth is fueled by the rising demand for highly accurate navigation solutions across defense, aerospace, and autonomous vehicle sectors. The increasing complexity of modern warfare, coupled with heightened geopolitical tensions, has made assured positioning, navigation, and timing (PNT) systems a national security imperative.

Government initiatives, such as the inclusion of PNT in the White House’s 2024 list of Critical and Emerging Technologies, underline the strategic significance of inertial navigation systems. Moreover, advancements in MEMS and fiber-optic gyroscope technologies are enabling more compact, efficient, and cost-effective solutions. These innovations are expanding the application scope beyond traditional aerospace uses, into industrial automation and autonomous systems—sectors demanding reliable, GPS-independent navigation.
