MISSILE SYSTEM

Home – Missile System

Missile systems are a cornerstone of modern defense, providing precise, long- and short-range capabilities to neutralize threats across air, land, and sea. At Sigma, we design and develop advanced missile systems that combine cutting-edge technology with unmatched reliability. Our solutions are tailored to meet the strategic needs of military forces, ensuring precision, optimal performance in the most demanding environments.

End Game Package

  • On-board module used in a guided missile triggers the detonation pulse based on commands from OBP and LPF
  • Using the 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

Electronic Delay Unit & Receiver Unit - Konkurs Missile

  • Integral component of the KONKURS-M system, designed to engage both stationary and moving armoured targets (Tanks)
  • Guides the direction of the missile
  • Communicates between the Control Drive Unit and BMP-II
  • Connects the control loop with the transducer of the gyro coordinator
  • Delays the time between pre-cursor charge warhead and main charge warhead
  • Delay time: 300 msec

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
  • QDAC communicates with the Missile Flight Control Computer (MFCC) via MIL-STD-1553 bus
  • The system operates on 28V DC supplied by the missile’s onboard battery
  • MFCC acts as the Bus Controller (BC), sending commands and receiving feedback every 10 milliseconds
