Key Developments

• Navigation System: A digital ring laser gyro–based inertial navigation system used in artillery, missiles and air defence platforms. It enables accurate positioning and targeting without dependence on satellite signals, crucial in electronic warfare conditions.
• Direct Firing Sight: An advanced sighting system for artillery and counter-drone roles, improving precision, reaction time and battlefield survivability.
• India Optel Limited will handle manufacturing, testing, quality control and life-cycle support in India.

Why It Matters

• Supports self-reliance in defence manufacturing and reduces import dependence.
• Reflects the shift in India–France defence ties from buyer–seller to technology collaboration.
• Enhances combat readiness in signal-denied warfare environments.

Q. Which of the following best explains the advantage of inertial navigation systems in modern warfare?

A. They rely on satellite-based positioning
B. They function independently of external signals
C. They are used only for civilian navigation
D. They are effective only in peacetime
