Le Bourget, France
Indian aircraft manufacturer Hindustan Aeronautics Ltd (HAL) has ordered 107 Sigma 95 navigation systems kits from Sagem (Safran) for the Indian Air Force’s combat aircrafts.
Developed and produced by Sagem, Sigma 95 is an autonomous hybrid inertial navigation system combining laser gyros and GPS/Glonass satellite navigation. It ensures high-precision navigation and broad operational flexibility for both combat and special-mission aircraft.
Two-thirds of the systems in this order will be manufacturered in India by HAL, further cementing the partnership agreeement on navigation systems signed by Sagem and Hindustan Aeronautics Ltd.
Sagem is a leading supplier of inertial navigation systems for Indian combat aircraft, warships and weapon systems. Nearly 500 combat aircraft deployed by the Indian air force and navy are now fitted with Sagem equipment. The systems in this latest order will join the Sigma 95 systems already in service on India’s combat aircraft.
Produced in Sagem’s Montluçon plant in the Auvergne region of south-central France, Sagem’s navigation systems are deployed on some of the world’s latest miliary aircraft,including the Dassault Rafale fighter, A400M military transport, NH90 helicopter and EC725 Caracal helicopters used by special forces.
GPS (Global Positioning System) and Glonass (GLObal’naya NAvigatsionnaya Sputnikovaya Sistema) are respectively the American and Russian satellite positioning systems.
Hindustan Aeronautics Ltd (HAL) has also entered into a contract with SAGEM for setting up of manufacturing and depot level maintenance facilities for Automatic Flight Control System (AFCS) LRUs (Line Replacement Units) including sensor at HAL facility at Hyderabad.
The Transfer of Technology (ToT) will enable HAL-Hyderabad to in-house manufacture and depot level maintenance of AFCS LRUs for ALH Dhruv helicopter, IJT trainer jet platforms. The possibility of fitting AFCS LRUs on the under development Light Combat Helicopter and Light Utility Helicopter platforms is also being explored
The automatic flight control system(AFCS) in an aircraft is coupled to the guidance outputs from an inertial navigation system (INS).
Sagem supplies flight control system for the HAL built ALH Dhruv helicopter. In addition, it makes Sigma laser gyro navigation systems,hundreds of which have been acquired for India’s Hawk trainers, Jaguar, MiG-27, MiG-29K, Sukhoi-30 MKI and LCA Tejas combat aircraft.
The Sigma 95N INS is based upon three highly accurate 32cm digital laser gyroscopes. It is equipped with a GPS or GPS/Glonass receiver and makes use of a powerful multimode Kalman filter to optimize performance by hybridizing inertial and satellite data.
