CM3-MR Direct Firing Sight and SIGMA 30N navigation system
Why in news?
India Optel Limited (IOL), a Mini Navratna Defence PSU, signed a collaboration agreement with France's Safran Electronics & Defense on December 22, 2025, for local production of the CM3-MR Direct Firing Sight and SIGMA 30N navigation system. These combat-proven systems enhance artillery precision and operate independently of GPS signals, aligning with India's Make in India initiative for defence self-reliance.​
CM3-MR Direct Firing Sight
- The CM3-MR supports direct-fire targeting for artillery guns and anti-drone operations, improving accuracy, reaction time, and battlefield survivability.
- IOL handles manufacturing, assembly, testing, quality control, and lifecycle support to meet Indian Army needs.​
SIGMA 30N Navigation System
- This digital ring laser gyro inertial system equips artillery, air defence, missiles, and radars for precise positioning in GPS-denied environments like electronic warfare.
- It enables autonomous engagement by detecting enemy firing locations rapidly.​
Significnce
- Operational Independence: Inertial navigation ensures forces can operate even if GPS is denied.
- Enhanced Accuracy: Direct firing sights improve hit probability against fast-moving or small targets like drones.
- Defense Diplomacy: Strengthens India–France defense ties, adding to earlier collaborations like the Rafale jets and HAMMER precision weapons.
Challenges & Considerations
- Technology Transfer: Ensuring full absorption of advanced tech into Indian manufacturing.
- Cost & Maintenance: High-precision systems require significant investment and upkeep.
- Integration: Seamless deployment across diverse platforms (artillery, missiles, drones) is critical.
