LN-200 FOG Family Advanced Airborne

LN-200 offers the lowest accel/gyro bias, lowest random walk and the highest mean time between failures (MTBF)

The LN-200 is a small, lightweight, highly reliable, state-of-the art, fiber-optic, all-altitude, strap down Inertial Measurement Unit (IMU). The LN-200 has three solid-state fiber-optic gyros and three solid-state silicon Micro Electro-Mechanical System (MEMS) accelerometers in a compact package that measures velocity and angle changes in a coordinate system fixed relative to its case. Digital output data of incremental velocity and incremental angle are provided to user equipment over a digital serial data bus. The LN-200 is hermetically sealed and contains no moving parts, ensuring low noise, long usage and shelf life. The LN-200 has been in high rate production since 1994 with over 40,000 units produced.

LN-200 Applications

The LN-200 is available in 0.5 and 1.0 deg/hr gyro bias classes of performance.

Any LN-200 can be installed with variations of software, including:

Attitude and Heading Reference System (AHRS)
Pipeline Inspection and operation in GPS denied environments
Electro-optical/FLIR / Camera / Radar Stabilization
Guidance
Fly-By-Wire (FBW) Flight Controls
ACMI/TSPI (Air Combat Maneuvering Instrumentation/ Time, Space, Position)
Motion Compensation

The AHRS version of the LN-200 is certifiable to DO-178B Level A.

LN-200 Advantages

The LN-200 FOG family is a hermetically sealed non-dithered, low-voltage inertial sensor, ensuring long, reliable usage life. It has the lowest gyro and accelerometer white noise and highest MTBF in the medium accuracy, tactical grade IMU class.

Advantages of LN-200C

The LN-200C fiber-optic gyro (FOG) inertial measurement unit (IMU) for commercial, aerospace and industrial applications gives customers from around the world greater flexibility and ease of use since it is only subject to Export Administration Regulation (EAR) for export control.

The commercial-off-the-shelf LN-200C is a small, lightweight and highly reliable FOG IMU. This compact unit consists of three solid-state fiber-optic gyros and three solid-state silicon Micro Electro-Mechanical System (MEMS) accelerometers that measure velocity and angle changes in a coordinate system fixed relative to its case. Digital output data of incremental velocity and angle are provided to user equipment over a digital serial data bus. The LN-200C is designed to be Form and Fit interchangeable with the LN-200 IMU. Performance differences are noted in the available brochure.
