Precision Guided Munitions

Why do you need Inertial Navigation System for Precision Guided Munitions?

Inertial Navigation Systems (INS) play a role in Precision Guided Munitions (PGMs) ensuring that munitions are accurately delivered to their intended targets. Here are a few reasons why Inertial Navigation Systems are crucial for the success of Precision Guided Munitions;
  • Independent Navigation - PGMs operate independently once launched and Inertial Navigation Systems allow them to navigate autonomously towards their designated targets. This independence is essential for ensuring the effectiveness of PGMs in scenarios.
  • GPS Challenges - Inertial Navigation Systems become especially important when PGMs operate in environments where Global Positioning System (GPS) signals may be disrupted or jammed. INS provides a navigation solution when GPS is unavailable or unreliable.
  • Continuous Guidance - INS provides real time guidance throughout the flight of the munition ensuring navigation information even in dynamic and rapidly changing environments.
  • Pinpoint Accuracy - PGMs are designed to deliver munitions with precision, minimizing damage and maximizing strike effectiveness. Inertial Navigation Systems contribute significantly to achieving this level of accuracy by providing positioning, velocity and orientation data.
  • Redundancy and Reliability - INS often works alongside guidance systems like GPS or laser guidance adding redundancy and enhancing reliability.

Inertial Navigation Systems offer capabilities that enable Precision Guided Munitions to navigate and overcome GPS challenges, provide continuous guidance, achieve pinpoint accuracy and ensure redundancy for reliable operation. This redundancy improves the reliability of the guidance system ensuring that the Precision Guided Munition (PGM) can maintain accuracy even if one component of the system fails or is compromised.


  • Mid flight Adjustments - Inertial Navigation Systems (INS) allow for adjustments to be made during the flight of the PGM. This capability enables the munition to adapt its trajectory based on real-time information increasing the chances of hitting a moving target or compensating for factors.
  • Navigation, in Complex Environments - PGMs may be deployed in environments, such as areas or regions with diverse terrains. Inertial Navigation Systems enhance the ability of PGMs to navigate accurately in environments avoiding obstacles and following a desired path.
  • Quick Maneuvering - By utilizing Inertial Navigation Systems, PGMs can perform precise maneuvers. This allows them to quickly respond to changes in the target's location or avoid obstacles effectively. Such capability enhances their versatility and effectiveness.
  • Reduced Dependence on External Signals - PGMs equipped with INS rely less on signals or guidance from ground based sources. This is essential for ensuring that these munitions can operate independently and maintain accuracy across scenarios.
  • Global Deployment - Inertial Navigation Systems provide flexibility for deployment of PGMs since they function independently without relying on ground based infrastructure. This enables the utilization of PGMs in geographical areas and operational environments. In essence, Inertial Navigation Systems have an impact on the accuracy and effectiveness of Precision Guided Munitions. They enhance the autonomy, dependability and precision of these munitions ensuring their ability to navigate and hit their intended targets with precision.
