Global Positioning System (GPS) technology powers navigation across military, aviation, maritime, and civilian sectors but remains vulnerable to jamming, spoofing, and signal interference. These threats, increasingly common in modern warfare, can compromise weapons accuracy, troop movements, and logistics.
To address these risks, India is developing a Quantum-based Magnetic Navigation System (QMNS) capable of delivering precise location data without relying on satellites.
By using quantum sensors to detect variations in the Earth’s magnetic field, QMNS creates unique magnetic signature maps for reliable positioning.
Unlike GPS, which depends on potentially compromised satellite signals, QMNS is self-contained and resistant to interference.
This enables accurate navigation in environments such as deep underwater, tunnels, or areas affected by electronic warfare.
The technology has critical defense applications.
Fighter jets, drones, and missiles can maintain targeting accuracy in GPS-denied zones, while submarines and AUVs can navigate stealthily without surfacing.
Ground forces can also operate effectively in dense terrain or underground facilities.
Beyond defense, QMNS offers potential in civil aviation, maritime shipping, and disaster recovery where GPS disruptions pose risks.
Challenges include miniaturizing hardware, building detailed magnetic maps, and scaling domestic manufacturing.
Aligned with Atmanirbhar Bharat, QMNS positions India to join global leaders in quantum navigation, enhancing both security and strategic autonomy.
