Quantum Navigation Market Size & Share 2026-2035

Quantum Navigation Market Size

The global quantum navigation market was valued at USD 1 billion in 2025. The market is expected to grow from USD 1.3 billion in 2026 to USD 3.5 billion in 2031 & USD 7.3 billion in 2035, at a CAGR of 21.6% during the forecast period according to the latest report published by Global Market Insights Inc.

The growth of the quantum navigation market is attributed to the increased dependence on GPS/GNSS-independent navigation solutions in the face of widespread jamming and spoofing in current environments, the increasing expenditure by defense organizations on resistant position, navigation, and timing (PNT) systems, continuous advancements in quantum magnetometers and atom-based inertial sensors, the potential for applications in aviation and maritime as well as robotic and autonomous platforms and the significant increase in public investment in quantum and other science and technology programs to develop next-generation navigation systems.

The quantum navigation market is significantly driven by the increased demand for GPS/GNSS independent navigation due to vulnerability of current PNT systems as they are vulnerable to electronic warfare. Jamming & spoofing systems are making conventional satellite-PNT systems insecure. For instance, the U.S. department of energy has already identified such issues, a heavy reliance on GPS has emerged as a serious security vulnerability to modern day warfare, development spurring research in quantum sensing PNT as alternatives to the technology. In such efforts, the development has stressed a focus on the need to anticipate GPS denied or electronic warfare (EW) situations and to that end defense agencies have begun expediting investment in atomic clocks, accelerometers, magnetometers, gravimeters, and other quantum sensors.^{[1]US department of energy, osti.gov}

Additionally, the market is growing due to the rise of government and defense investment in hardened quantum-based positioning, navigation and timing systems that allow nations to secure positioning capabilities during any satellite interruption to navigate. For instance, the Australian government announced that four Australian-developed quantum clocks had been successfully trailed in the United States under AUKUS pillar II following a USD 2.7 million government investment. The clocks were evaluated under different environmental conditions for potential defence applications including navigation and communications, with the government highlighting their ability to support GPS spoofing and jamming detection and reliable PNT in contested environments.^{[2]Australia defense ministry, defense.gov.au}

The quantum navigation market increased steadily from USD 603.3 million in 2022 and reached USD 836.7 million in 2024, driven by increased demand for a GPS/GNSS free navigation system and increasing investment from governments in developing protected positioning, navigation and timing (PNT) systems that are immune to interference. There was also increasing paranoia of GPS spoofing & jamming for which quantum-assisted devices are the best defense, contributing to more substantial gains. Enhanced capabilities of quantum inertial sensors, atomic clocks, and atomic magnetometers, increased utilization of quantum-sensing technologies across aviation and defense platforms and increased government spending on the advancement of technologies also fueled substantial market penetration.
