Fiber Optic Gyro IMU

 FIMU63 fiber optic inertial measurement unit FIMU63 fiber optic inertial measurement unit product is a highly cost-effective inertial measurement equipment, and with broadband, high resolution, small zero drift, high linearity, short start-up time, strong impact resistant and anti vibration ability, small volume, low cost characteristics, is Lipton company in the United States LN-200S fiber optic IMU domestic ideal substitute.A number of key technical indicators Habitat domestic leading level in the same type of products. Using integrated optical fiber polarization technology, crosstalk suppression circuit technology, full temperature （-40°C~+60°C）dynamic error compensation, realize the gyro in the entire temperature range of zero bias stability 1°/h ; adopting high precision closed loop demodulation algorithm, gyro has high scale factor linearity and lower random walk; Using gyroscope and accelerometer/circuit integrated design technology, system has small volume, weight and power consumption; using phase tracking technique, gyro dynamic measurement range up 2000 °/s, broadband is better than 200Hz.It can adapt to bad environment, also can be used in a variety of work in the military field. Using harsh environment adaptability design technology to ensure products in the complicated mild mechanical environment of stable and reliable work and maintain measurement accuracy; adopts a fully sealed design, can be adapted to high humidity / water and other work environment, and ensure the long-term stability of inertial device; follow a strict manufacturing process, manufactured products were fully tested and stress screening test and Products with an average failure free time of up to 50000 hours.Rich expansion capability, good user experience. The use of multi-core high performance CPU, can achieve 1s information output, 2000Hz inertial instrument data acquisition and error compensation; with wide voltage, single power supply mode, reducing the requirements on the power input; rich interface, it can be applied to RS-422/232 interface,etc; broadband systems, the data update rate, the baud rate can be adjustment, the user can make the optimal allocation according to the application field; system can be upgraded to the strapdown inertial navigation system / vertical gyro under the condition of the same hardware resources, and can be connected to the GPS/ magnetic /DVL/ mileage meter / altimeter and other kinds of transmission expansion as a combination of navigation system. Fiber Optic GyroscopeElectrical/Mechanical InterfaceMeasurement Range (max)±2000 °/sPower Supply8V~16VBias Stability1°/hPower8W(max）5W(tipical）Bias3°/hRun-up Time1sScale Factor   Nonlinearity50ppmCommunication InterfaceRS-422,RS-232Broadband>1000HzUpdate Rate1Hz~2000HzAngle Random Walk0.02°/ √ HzDimensionØ63×92（mm）AccelerometerWeight<0.6kgInput Range(max)±20gOperating EnvironmentBias1mgOperating Temperature-40 ° C~+60 ° CBias Stability1mgStorage Temperature-55 ° C~+70 °  CScale Factor Nonlinearity500ppmVibration6.06g(RMS)Shock9g/11ms
