FOG Inertial Measurement Unit (FMU)
The FOG Inertial measurement unit (FMU) is an integral component of flight control systems. It consists of three fiber-optic gyroscopes (FOGs) and three high-performance accelerometers. The FOG-P and IMU-Kernel are temperature-calibrated within the operational range. These units are a cost-effective ITAR-free solution. The Inertial Labs FOG units use extensive calibration techniques and are able to compete with any FOG unit on the market today.
FOG-IMU-based systems are available in two configurations, 0.5 deg/hr and 1.0 deg/hr. They are subject to Export Administration Regulation. They are suitable for military, commercial, and industrial applications. The U181 offers low-noise performance and is available in an aluminium housing. Its advantages are similar to those of FOG-based systems. iFOG-IMU-1 is suitable for most aircraft and is manufactured in Germany.
The FOG-IMU-1A combines three fiber optical gyros with three servo-accelerometers in closed-loop technology. This sensor has high reliability, is larger and requires more power than the MEMS version. Because of its low power consumption and small size, it is the preferred choice in demanding high-temperature and high-vibration environments. On the other hand, the MEMS-based FOG-IMU-1B features the same core sensors but is smaller. Both types are shock-mounted and triggerable.
The LN-200CY is a compact, highly reliable FOG-based IMU. The device has three MEMS accelerometers and a VG-1703-like gyroscope. The digital output of the FOG-200C is the incremental velocity and angle, which is sent via a serial data bus to the user equipment. The LN-200C and LN-200 IMU are intended to be interchangeable. The differences between them are performance-related.
The FOG-based Inertial Measurement Unit is an IMU that incorporates three MEMS accelerometers and three VG1703-like gyros. The FOG-based IMU is more expensive and requires more power than the MEMS-based units. However, FOG-based IMUs are ideal for high-temperature and high-vibration environments. The accuracy of navigation systems is significantly improved after calibration.
The FOG-based IMU combines three MEMS accelerometers with a VG1703-like gyroscope. Its low power consumption and instant initialization make it a popular choice for multispectral day/night observation. The U181 offers excellent accuracy and is compatible with a variety of other AVMS. The iFOG-IMU-1 is a reliable and affordable option.
The EN-300 is a high-performance Fiber Optic Gyro-based IMU. Its dual-channel design enables it to be used with a wide range of applications, including GNSS-denied navigation. The EN-300 is ideal for line-of-sight stabilization and precision targeting. It is a form-compatible FOG inertial measurement unit. It also supports multiple GNSS-enabled devices.
