LLN-G1 Details

After many years of successful operation in mortars, battle tanks and armoured personnel carriers, LLN-G1 received a new gyro unit (FOG-IMU) as well as additional interfaces to display and control devices as well as guidance systems. While retaining logistical compatibility, the current generation comes with MILBUS, RS-422, CAN-BUS or Ethernet interfaces to the avionics.

LLN-G1 supports standard NATO GPS receivers as well as several commercial GPS receivers. The combination of gyro unit with an external GPS receiver constitutes a cost-effective solution for the life cycle of a vehicle navigation system in military use. With an anticipated service life of more than 20 years, the logistical replacement of the GPS component (e.g. to M-code GPS) must be possible with minimum conversion effort. The inertial component (FOG-IMU) is retained when the GPS receiver is replaced, and this assures a reliable navigation solution even if the enemy is using jammers.

In standard mode, LLN-G1 provides a hybrid navigation solution, i.e. optimum positioning and heading information calculated from the sum total of sensor data. All LITEF navigation systems are developed, acceptance tested, produced and supplied right around the world in and from Freiburg. Since the sensor solution as well as the navigation algorithms are all from a single source, LITEF Land Navigators (LLN) provide a hitherto unachieved level of system integrity upon which the driver, commander and the higher-level guidance system can depend.
