Republic of Korea to receive land navigation systems for K21 IFV from Northrop Grumman

Northrop Grumman Corporation 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 new K21 infantry fighting vehicle (IFV), announced Northrop Grumman Corporation. 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 state-of-the-art fibre optic gyros and micro-electromechanical system (MEMS) accelerometers developed and manufactured by Northrop Grumman LITEF in Freiburg, Germany. Combining inertial sensors with an odometer and GPS data, the LLN-G1 provides accurate and uninterrupted 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," said Norbert Sandner, director of marketing and sales for Northrop Grumman LITEF. "This new contract for the series production phase of the K21 IFV is the second LLN-G1 order for the K21 vehicle, and we are pleased that our systems have again been chosen as an integral part of one of the most advanced IFVs currently available".
