Freiburg, Germany - Northrop Grumman has been awarded a contract by Korean military systems and vehicle manufacturer Doosan DST Co., Ltd. to deliver inertial navigation units for the Republic of Korea's K21 infantry fighting vehicle (IFV). The LLN-G1 units will be built by the company's German navigation systems subsidiary, Northrop Grumman LITEF.
The LLN-G1 is a hybrid land navigation system based on fibre optic gyros and micro-electromechanical system (MEMS) accelerometers developed and manufactured by Northrop Grumman LITEF in Freiburg. The system combines inertial sensors with an odometer and GPS data to provide three-dimensional position and attitude data for vehicle commanders and crews.
"Unjammable situational awareness in combination with gyro-compassing is exactly what the commander of a modern IFV like the K21 needs to effectively carry out his mission. Normally found in high-end inertial reference systems, the gyro compassing capability enables the LLN-G1 to establish precise heading without the use of a magnetic compass," explained Norbert Sandner, director of marketing and sales for Northrop Grumman LITEF.
