Laser Inertial Measurement Unit

ER-1D Laser Inertial measurement unitER-1D Laser Inertial measurement unit is composed of three Miniaturization of laser gyro, Mounting support and Absorber. According to user’s requirement, user can choose if accelerometer, secondary electric power supply, computer board are needed. With the unit, we can get accurate measurement information carrier which relative to the angular motion of the inertial space. The output data form is Angle increment form. It can be used in products’ develop and research of Inertial integrated navigation, positioning direction, attitude position measurement etc. Features:l   Can set compensation model, high precision, long time working stabilityl   Many kinds of interface, can be customizedl   Small volume, light weight, high environment adaptation Application:l   Airborne integrated navigation system integrationl   Stationary positioning directional system integrationl   Mobile measurement system of heading attitude accurate measurementl   High-speed rail measurement systeml   High precision servo control application Specifications: No.ItemIndexRemarkA levelB level1Angular rate measurement dynamic range≤±300°/S2Bias≤±0.5°/h≤±0.5°/h3Bias stability≤±0.015°/h≤±0.020°/h1σ4Bias repeatability≤±0.015°/h≤±0.020°/h1σ5Acceleration range±30g±30gCustomized6Acceleration Bias stability0.05mg0.1mg7Acceleration Bias Repeatability0.05m0.05m8Starting time＜20S9Temperature-40℃~70℃10Impact15g/30g11Volume212mm*195mm*175mm12Weight≤17Kg13PowerAccelerometer: +5V1, +5V2, -5V,   ±15VGyroscope: ±5V, +12V, -12V1,   -12V214InterfaceRS42215Data refresh400Hz16Baud rate230400bps
