The LN-200 inertial family of fiber-optic gyros (FOG) offers the lowest accel/gyro bias, lowest random walk and the highest mean time between failures (MTBF).
The LN-200 is a small, light weight, 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 25,000 units produced.
LN-200 applications
The LN-200 is available in 0.5, 1.0 and 3.0 deg/hr gyro bias classes of performance.
Any LN-200 can be installed with variations of software, including:
- Attitude and Heading Reference System (AHRS)
- Motion Compensation
- Electro-optical/FLIR / Camera / Radar Stabilization
- Guidance
- Fly-By-Wire (FBW) Flight Controls
- ACMI/TSPI (Air Combat Maneuvering Instrumentation/ Time, Space, Position)
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 IMU class.
