Helmet Mounted Display System 
  • Helmet Mounted Display System  is meant for determination of angular co-ordinates of visually observable target, as per movement of pilot head.
  • System panel is intended for data reception, entry, processing and display of information as well as for selection of mode. 
Sigma Inertial Navigation System (INGPS)Inertial Navigation and Global Positioning System (INGPS) 
  • Inertial navigation is a process which allows a vehicle to locate itself in space (position, speed and attitude). INGPS is based on “strap-down” navigation systems. In such systems, all output values are calculated based on information delivered by the angular rotation (Ring Laser gyros) and linear acceleration (accelerometers) detectors. GPS Information is used to compensate the effect of inertial parameters drift, in order to compute optimal navigation data. The INS/GPS (Inertial Navigation System/ Global Positioning System) SIGMA 95 is a Strap down Inertial Navigation Unit (INU) based on Ring Laser Gyro, accelerometers and GPS receiver. It is licensed from M/s Sagem France now M/s Safran Defence & Electronics, France.
