Missile Systems

We engineer and manufacture missile systems that sit at the heart of India’s most critical guided weapons programmes. Every component is qualified, fielded, and built to perform where there is no margin for error.

End Game Package

  • On-board module used in a guided missile that triggers the detonation pulse based on commands from OBP and LPF
  • Using predefined internal logic, initiates the detonation pulse for the time delay
  • Accepts commands and inputs from On Board Processor (OBP) and Laser Proximity Fuse (LPF)
  • Computes time delay using internal logic and algorithm to issue detonation pulse for maximum impact

Amplifier for INVAR Missile

  • Integral component of the INVAR Missile system, designed to engage both stationary and moving armoured targets (Tanks)
  • Connects the control loop with the transducer of the gyro coordinator
  • Carries out on-board signal processing

Quad Digital Actuator Controller (QDAC)

  • Missile flight control system uses a cruciform fin configuration
  • Four (4) fins, each controlled by a linear electro-mechanical actuator
  • Actuator consists of a BLDC motor driving a ball screw/nut mechanism
  • Linear motion is converted to rotary motion using a crank arm
  • Position feedback is provided by a contactless potentiometer
  • Single enclosure houses four (4) Digital Actuator Controllers (DACs)
  • Each DAC controls one actuator
  • DAC drives the BLDC motor using PWM through a hex MOSFET bridge
