Northrop Grumman has announced that it will be delivering inertial navigation units for the Republic of Korea’s new K21 infantry fighting vehicle (IFV).

The LLN-G1 is a hybrid land navigation system based on state-of-the-art fibre optic gyros and micro-electromechanical system (MEMS) accelerometers. 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.

Director of marketing and sales for Northrop Grumman LITEF Norbert Sandner said that un-jammable situational awareness in combination with gyro-compassing was exactly what the new vehicle needed.

“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 Sandner

“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.”

The contract was awarded by Korean military systems and vehicle manufacturer Doosan DST Co., Ltd. The LLN-G1 units will be built by the company’s German navigation systems subsidiary, Northrop Grumman LITEF.
